Biosurfactant and Heavy Metal Resistance Activity of Streptomyces spp. Isolated from Saltpan Soil
並列摘要
Actinomycetes were isolated from the marine soil samples collected at the Ennore saltpan and were screened for biosurfactant and heavy metal resistance activity. Biosurfactant activity was evaluated by haemolysis, drop collapsing test and lipase production. Similarly heavy metal resistance was determined by tube method and agar diffusion method. Among them, two actinomycetes isolates VITDDK1 and VITDDK2 exhibited significant biosurfactant and heavy metal resistance activity. Based on the Hideo Nonomura's key for classification of actinomycetes, the isolate VITDDK1 was similar to Streptomyces orientalis and VITDDK2 to Streptomyces aureomonopodiales. However molecular phylogeny based on neighbour-joining method showed 99% similarity of VITDDK1 with Streptomyces sp. A403Ydz-QZ and 93% similarity of VITDDK2 with Streptomyces sp. strain 346.
