scrutinizing the applications of mangrove actinomycetes mediated biosynthesized copper nanoparticles

Recently, there has been an increase in research interest in metal nanoparticles and their synthesis becauseof their various applications in different industrial areas. the current study deals with the actinomycetesmediatedsynthesis of copper nanoparticles (cunps) isolated from mangrove soil and to further access itsapplication in different fields. eight different soil samples were collected from three different mangrovesites located in mumbai. a total of 15 different actinomycetes isolates were obtained from soil samplesand studied in the present investigation and were screened for metal tolerance. it was found that out of15 isolates, only 3 were able to tolerate the highest metal salt concentration i.e. 10-1m. the synthesizedcunps were further investigated with various characterizations such as uv-vis spectroscopy, ftir, and xrd.the identification of isolate grc1 was done as per bergey’s manual of systematic bacteriology volume5 for preliminary identification of actinomycetes and was identified as streptomyces sp. this isolate wasfurther characterized by vitek ms and it was identified as streptomyces verticillus. the inhibition zoneby biosynthesized cunps was significantly greater when compared with standard antibiotics and cuso4.the calculated degradation efficiency after 5hrs of incubation was 59.67% and 96.26% for red m8b andreactive green, respectively. prevention of biofilm formation by cunps was confirmed by microscopictechnique and significant inhibition of biofilm was observed. thus, the mangrove actinomycetes mediatedbio-fabrication of cunps should gain much attention because of their unique properties like antimicrobial,anticancer, catalytic activity, wound healing, and antifouling.
