A total of 66 actinomycetes isolates were isolated from mangroves of Andhra Pradesh, India, using various enrichment techniques and pre-treatments. The samples were collected from Coringa mangrove ecosystem and pre-treated by enrichment with CaCO3, sodium dodecyl sulphate and phenol, plated on the media supplemented with cycloheximide (50mg/mL), nystatin (25mg/mL) and nalidixic acid (50mg/mL). The population count of actinomycetes fluctuated from 19x104 to 80x104 g soil-1. Out of the isolated 66 actinomycetes, 8 isolates possessing plant growth promoting potential were further studied and characterized by physiological, biochemical traits and identified by 16S rRNA gene sequencing as different species of Streptomycetes genera.
