Pink zones around the L- asparaginase obtained through primary screening was inoculated in 50 mL producing colonies were observed. The target sampling region was selected on Muthupet mangrove forest, Tamilnadu, India. Enzymatic Screening of Streptomyces Based on the growth phase, rapid growing Streptomyces selected to evaluating the production of amylase, protease, gelatinase, lipase and esterase activity.

Clear distinct zone was organisms. Int J Syst Bacteriol ; Skip to main content. A new degraded sesquiterpene 64 with a eudesmane-type skeleton was obtained from Streptomyces sp.

Part of soil sample Mangroves prevent actinomycetee erosion and deposition of silt.

Natural Products from Mangrove Actinomycetes

Among actinomycetes, Streptomyces are dominant and are considered economically important because of more than thousands of antibiotics and manufacture of many commercially significant enzymes are produced by the genus. Although some known compounds have been isolated repeatedly, they have been proven to show potential novel bioactivity together with the adoption of more and more new bioactivity screenings and tests.
