Is Human Pheromone Spray Really Effective? 

Human pheromones in their natural sense have been identified as being the silent attractant between men and women but can they prove useful in an artificial sense? Is it possible to use a pheromone spray and create that invisible magic leaving your competition "wallowing in your wake."

We have used clear and concise words in this article on pheromone cologne for women to avoid any misunderstandings and confusions that can be caused due to difficult words.

Most of these signals can be used both subtly and effectively in almost any setting. Licking a dollop of whipped cream could be perfectly acceptable in a Starbucks or bookstore cafe. Playing with your hair and looking a man in the eyes would be perfectly natural as you walk out of your favorite salon.

There are things that you can do to be instantly more attractive to men. Some of these secrets involve the way you dress and apply your makeup, some involve the type of scent that you use and how you apply it and some involve more in depth seduction techniques and body language.

a) Among these 17 producers strain 6 strains were isolated from Hypnea musiformis. 6 from Gracillaria edulis, 4 from Ulva lactuca & 1 from Sediment.

MATERIALS AND METHODS: SAMPLE COLLECTION: Seaweed samples were collected from Gulf of Mannar Marine Biosphere Reserve and identified up to species level by using CMFRI bulletin (14) as follows:

Attracting a man is never as difficult as we make it out to be. You are born with the knowledge of how to give off the right signals. Let go of your shyness, practice and suddenly you will realize how natural flirting and attracting men can be.

c) The normal 20 bacterial strains isolated from 20 algal species were crossed with terrestrial bacteria such as E-coli, Staphylococcus aureus separately

Studies seem to prove conclusively that odorless compounds have a certain effect on human bevaviour. You've only got to do a search for Dr. Winifred Cutler online who has led the way in human pheromone research during the past three decades to realise this is not a subject where claims are baseless. Amazingly, it's also being suggested that pheromones are gender specific; that is only a human pheromone can generate a human response and even more enlightning; heterosexual to heterosexual and homosexual to homosexual. Is it possible?

ABSTRACT Bacterial biofilms are sessile communities with high cell density that are ubiquitous in natural, medical, and engineering environments; they are fascinating since they are primitive tissues with an advanced chemical communications network. Currently, there is an explosive amount of biofilm research, most of it with the ultimate aims of biofilm prevention, control, or eradication.The present investigation was aimed to study the cell signaling principle among seaweed epibiotic bacterial organisms , totally 54 bacterial isolates were made out of 20 seaweed species. Among 54 bacterial isolates 17 of them producer, another 17 of them inducer strains rest of 20 isolates were normal that have not showing any signs of activity. The 17 producers and 17 inducer strains were subjected to the cross species induction by quorum sensing principle and found that only 3 of them have responded to the cross species induction in production of antibacterial compound against the respective inducer strains. All the 3 producers and inducer were identified by biochemical analysis and surprisingly that all the 3 producer strain belongs to Genus Pseudomonas and inducer strains were belongs to Genus Vibrio. The supernatant obtain from mixed culture of Pseudomonas & Vibrio shows the antibiotic activity against the various Vibrio species which were isolated from other sources. Such as Vibrio from primary film, Vibrio from sediment Vibrio from seaweeds epibiotics. The obtain results clearly shows the particular Pseudomonas from seaweed epibionts has the capability of producing potential antibiotic compound against wide range of Vibrio species through quorum sensing.

Every creature on this planet gives off attraction signals. We are no exception. Some are blatant and some are unconscious. We are all born with the ability to physically attract others. Some of us have just cultivated this gift.

EXPERIMENT NUMBER 2 In this experiment, culture supernatant was obtained as per the procedure given in the experiment 1. 50ml of supernatant was mixed with equal volume of 80% methanol and 1% acetic acid mixture and it was shaked thoroughly in a separating funnel. Finally the methanol and acetic acid fractions were collected and concentrated by evaporation using water bath at 55??C. The viscous colloidal residues were resuspended in 600 microlitre of 50% methanol and it was used for antibacterial assay against different test organism.

Human Pheromones And Business

You're a businessperson who has an appointment with a client today and the deal is worth a lot of money. Gaining the confidence of that client from the outset is your first task. How can you get him or her to take an instant liking to you? Can a simple shot of pheromone spray be the difference between closing or losing the deal? I'm only surmising here and it sounds a little like science fiction but ask yourself if you are in business… just what if? It's interesting food for thought.

Seaweeds itself secretes secondary metabolites to prevent fouling and grazing. In addition to that epibiotic bacteria on macro algae can also produce antifouling compounds that work in concert with the seaweed derived compounds to protect the seaweed surface. Recent studies have highlighted important roles of epibiotic bacteria colonizing the surface of seaweeds and releasing antifouling compounds. For the past 50 years antibiotics have revolutionized medicine by providing cures for formerly life threatening diseases. However, strains of bacteria have recently emerged that are virtually unresponsive to antibiotics such multidrug resistance, arising mainly through antibiotic misuse, is now recognized as a global health problem. In this situation, it is clear that new classes of antibiotics are urgently needed. Many marine bacteria have been shown to produce secondary metabolites that display antibacterial properties. The first antibiotic from a marine bacterium was identified and characterized in 1966. In addition, bacteria in biofilm on the surface of marine organisms have been documented to contain a higher proportion of antibiotic producing bacteria than some other marine environments (Burgess, et al., 1999). Marine epibiotic bacteria, associated with nutrient-rich algal surfaces have also been shown to produce antibacterial secondary metabolites which inhibit the settlement of potential competitors. Recently a lot new novel antibiotics such as Phenazine, thiomarinol, phenazine-1-carboxylic acid, 1-hydroxyphenazine 2-n-heptylquinol-4-one, 2-n-nonylquinol-4-one pyolipic, loloatins, agrochelin, sesbanimides, pelagiomicins, indomycione and indomycione have been identified from various marine epibiotic bacterial organisms. In particular, some species of the genus Pseudomonas produce both antibiotics and several other bioactive substances. For example, Pseudoalteromonas rubra and Pseudoalteromonas aurantia have been reported to be antibiotic producing bacteria. The phenomenon of higher organisms utilizing their associated microflora for the production of beneficial secondary metabolites is common in the marine environment (Yotsu, et al., 1987). A study of bacteria isolated from marine algae surfaces indicated that the incidence of antibiotic producing strains from this habitat was 20% whereas that from sea water was only a few percent. In addition, some bacteria that previously did not produce any active compounds have been found to be producing such metabolites when they are exposed to other bacterial species or extra cellular chemical from other bacteria. Bacteria may also produce antimicrobial compounds when they sense the presence of competing organisms. However, few attempts have been made to study such chemical communication between different bacterial species or how this might affect. The secretion of antimicrobial compounds (Mearns-Spragg, et al., 1998). Bacterial communication by the chemical signals for specific function is simply known as Quorum sensing. In which a bacterial population receives input from the environment and elicits an appropriate response (Hiroaki and Kristina. 2003). The term "quorum sensing" describes the ability of a microorganism to perceive and response to diffusible signal molecules. Bacterial cells sense their population density through a sophisticated cell to cell communication system and trigger expression of particular genes. Tne first system of density-dependent regulation was studied in detail with the luminescence of Photobacterium fischeri (formerly known as Vibrio fischeri) by Bassler et al., 1997. Eventually, they discovered that 3-oxo-N-(tetrahydro-2-oxo-3-furanyl) hexanamid or N-3-(oxohexanoyl) homoserine lactone (OHHL) was responsible the agent in the broth that induced luminescence. Followed by this many researchers have confirmed that in Gram negative bacteria acyl-homoserine lactone is responsible for the cell to cell communication system.

In concluding this discussion, the quorum sensing is wider spread among bacterial population then was previously thought, (In Gram positive, Gram negative bacterial communication). Current assays for antimicrobial activities are inadequate because some antibiotic producing bacteria may require the presence of another bacterial species. These findings have important implication for the discovery of novel antimicrobial compounds from marine bacteria and may allow the development of new methods for screening novel compounds active against multidrug resistant bacteria.

Quorum sensing usually focused on the bacteria growing in homogeneous environment. However few studies have attempted to a study this principle in heterogeneous environment also. In this present investigation we have attempted to study both homogeneous as well as heterogeneous environment. In former one we have isolated producer strain in seaweed eipbionts and it shows inhibitory activity against the inducer organism at the same seaweed epibionts. Later producer strains from seaweed epibionts, were treated with various Vibrio organisms from different environment. The obtain result of this study shows that the producer strain are capable of secreting antibiotic compounds not only to their natural competitors in its own habitate but also to the pathogen inhabiting in a distant related environment.

In the present investigation, it was aimed to produce the antibiotics from the seaweed epibionts through quorum sensing principle. The bacterial isolates of seaweed epibionts were identified as species of Pseudomonas and Vibrio from seaweeds Hypnea musiformis and Gracillaria edulis. In this study the Pseudomonas acts as a producer strain and Vibrio as inducer strain. The recent finding says that the seaweed epibionts having potential to control the metabolic activity of competitor organisms. Allison et al., 1998 reported that many bacterial strains up on attaching to a surface produce exopolysaccharides or exopolypeptides. In addition, it has been postulated that exopolysaccharides could mediate the attachment of the bacteria to the surface and induce metabolic changes.

The collected seaweed samples were thoroughly washed with sterile seawater to removes the loosely attached bacteria/particles. Seaweed fronds were scrubbed with sterile cotton swabs to obtain epiphytic bacteria. Epiphytic bacterial organism in the swab were inoculated in sterile peptone broth (50% sea water) and incubated at 28??C in an incubated shaker (220 rpm / min) for overnight. After the incubation period the enriched cultures were serially diluted up to 10-8 concentration and 200 microlitre of each diluted samples were transferred into the nutrient agar plate (50% sea water). The plates were incubated at 28??C for 5 days and the plates with crowded colonies were selected. In the crowded plates those colonies, which showed the sign of inhibition zone around its margin to the neighboring colony, were selected and considered as producer strain. The neighboring sensitive colonies were treated as inducer strain. Both producer and inducer strains were streaked repeatedly until to get pure culture. The pure culture were properly labeled and subjected to the quorum sensing analysis.

This experiment does not showed any inhibition zones Bacterial identification The 3 producer and 3 inducer strains which were responded the quorum sensing principles alone were subjected to biochemical analysis for identification. The obtained results revealed that all the producer strains showed sings of Pseudomonas sps and the inducer strains showed signs of Vibrio sps. So, based on the obtained result all the producer strains seems to be a Pseudomonas sps where as all the Inducer strain belongs to the genus vibrio.

Attracting and seducing men is not as difficult as many of us make it out to be. As women, we naturally send out signals. The key is to know when to send them out and which ones to use. Watch any movie and the woman will show her interest in her man in several ways - meeting his eyes, leaning in to hear what he is saying, licking her lips, crossing her legs, twirling her hair around her finger, etc.. We do this naturally, even unconsciously.

Pheromones are odorless and are sensed by an organ located in the nasal passage called a VNO (vomeronasal organ). It's described as a type of "sixth sense." The question of whether human pheromones can be produced in fragrance form has long been debated but it hasn't stopped the marketing of such products available today. Pheromone spray is real and has opened up a lucrative market for those savvy enough to recognize the power of this concept. The problem is identifying which products are genuine and which are just out there to make a buck. There is a simple way of determining which pheromone sprays you should consider.
