ABSTRACT

Mangrove environments are known to be unique as they are exposed to both terrestrial and marine environments. They were also reported to harbor novel microorganisms and are still one of the least explored regions for biodiversity. Of the various groups of microbiotas that thrive in such environment, actinomycetes are one of the most prolific that are known for their therapeutic potential. Mangroves of Surat and Navsari districts of Gujarat of Western India were least studied in comparison with other mangrove regions of India. In the present study, Avicennia mariana rhizosphere samples of various dilutions from eight different locations of Surat and Navsari were analyzed for actinomycetes populations, in three different actinomycetes media (Actinomycetes isolation agar (AA), Starch casein agar (SCA) and Inorganic salt starch agar (ISSA)). Of all the dilutions tested 10-6dilutions gave the highest number of morphologically different colonies. There was statistically significant effect of sample site (p=0.000) in comparison with culture media (0.058) on the cultivable number of actinomycetes. The beta diversity was also shown to be affected by the media and sample site. Keywords: Mangroves, Actinomycetes, Culture media and Sample site
