Volatile oils are one of the groups of secondary metabolites produced by some plants. Their probable users against burn microbes have received little attention. Burn swabs obtained from ten burned patients at Government hospital, led to the isolation of bacteria using standard methods, the microorganisms were isolated. Then chloroform, methanol and aqueous extract of volatile of Ixora Cocciniea against S.aureus, E.coli, Pseudomonas aeruginosa, P.vulgaris and K.pnemoniae exhibited antibacterial were found efficacious respectively.

Fatty acid (UFA) biosynthesis is essential for the maintenance of membrane structure and function in many groups of anaerobic bacteria. In this study isolation of cellular fatty acid distributed in unknown rhizobial strains collected from five different soil samples by pour plate method using YEMA medium. The five soil sample are namely Klt 1, Alg 2,Bdl 3, Rf 4 and Mdk 5.The isolated rhizobial sample was identified based on morphological and biochemical characterization. Then the purified culture was mass multiplied and used for isolation of fatty acid. The fatty acid profile of five different rhizobial isolates were identified by GC and the result of fatty acid was totally seven fatty acids from Rhizobial isolates. Among them the Myrestic acid (C:14) were present all the isolates respectively.

In this study, the nutritional values of dietary mushrooms-Pleurotus indica that are very popular among the cultivated mushrooms in India have been determined. P.indica is widely cultivated as it is rich in nutrients and its component. P.indica is useful in biomass production in commercial level as it contains proteins and minerals. In this study the value added biochemical compounds in P.indica were analyzed from cultures. The amount of total carotenoids, protein, vitamin, pigments and phenolic compounds were examined. P.indica extracts possessed great potential antibacterial activities against four bacterial strains with inhibition zones ranged 8-15mm and MICs values ranges from 25-40ɥg/mL. Thus, it could be suggested that the P.indica is useful biosystem for production of biochemical compounds possess an antimicrobial principles.

In this study six fungal species were isolated from soil samples. Among the six species Glomus fasiculatum and Gigaspora marigarita noted in dominant level. So both are used as bioinoculant and were mass multiplied in onion plant by pot culture. After pot culture, biochemical and antibacterial activity were analysed from the treated plant Solanum surattense. In the phytochemical analysis falvonoids, tannins , terpenoids, cardiac glycosides and saponins were noted. Antibacterial activity of ethanolic extract of Solanum surattense against clinical isolates were analyzed and show the more activity noted in K.pneumoniae when compared with Bacillus subtilis, Streptococcus pyogens, E.coli respectively.
