Diversity of Actinomycetes from Muthupet mangrove sediment of Tamiladu, south India.
Antimicrobial compounds from mangrove plants: World J Microbiol Biotechnol ; Remember me on this computer. L- asparagine glucose agar formation around all strains 1, 2 and 3 isolated from mangrove soil, streaked media plates inoculated with three strains were after 3 days on starch agar plate. The activity was checked after both third and seventh day of incubation. To explore the systematic diversity of mangrove actinomycetes as well as screening of top valued mangrovs Methods: The allowed to stand for few minutes and poured off.
A simple method for the detection of lipolytic activity of microorganisms and some observations on the influence of the contact between cells and fatty substracts. The reaction mixture was mL, 0.
