Bioprospecting of Neem for Antimicrobial Activity against Soil Microbes

The Present studies was carried to evaluate the antimicrobial activity against soil microbes which causes corrosion on buried metal in acidic mediated soil by agar well diffusion using aqueous and ethanol extract of Neem leaves. These plants were subjected to solvent extraction with water and ethanol on increasing the polarity to identify and isolate the antimicrobial active materials. Crude aqueous extract of Neem is significantly inhibited the important microbes which causing corrosion such as S. aureus, Streptococcus, B. subitilis, Lactobacillus, Proteus, Cornybacterium, Pseudomonas, A.niger, Mucor and Desulphovibro sp. Results of the present studies investigation suggests that Neem are important effective plant for further work on isolating and characterizing of antimicrobial active materials.
