Isolation of endophytic actinomycetes from Syzygium cumini and their antimicrobial activity against human pathogens
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 1
Abstract
Isolation of endophytic actinomycetes is an important step to screen antimicrobial compounds to curb the threat of drug-resistant strains of human pathogens. Out of the 50 endophytic actinomycetes obtained from surface sterilized root, stem and leaf tissues of Syzygium cumini, 50 isolates (30%) exhibited antimicrobial activity. Antistaphylococcal activity was displayed by most of the isolates, with maximum percent inhibition by J-10 (Mean of Inhibition Factor=12.12 mm2). A total of 8 isolates (4 each) were able to hydrolyse protein (proteinase activity) and solubilize chitin (chitinase activity). Results of thin layer chromatography confirm the production of chloramphenicol family |antibiotic by the isolate J-5. This is the first report providing an insight into untapped endophytic actinomycete milieu of Syzygium cumini yet to be explored which might be a promising source for novel antimicrobial agents.
