ANTIMICROBIAL AND ANTICANCER ACTIVITY OF SILVER NANOPARTICLES FROM EDIBLE MUSHROOM: A REVIEW

ABSTRACTBiologically inspired nanoparticle synthesis is currently a rapid expanding area of research in nanotechnology. Nanoparticle synthesis utilizing thebioresources such as plants and microbes appears to be a viable, low-cost, and eco-friendly approach. Especially mushrooms can be used for largescalesynthesis of silver nanoparticles as mushroom produces many proteins that reduce the silver nitrate during the biosynthesis. Silver nanoparticlescan be characterized using ultraviolet-visible (UV-VIS) spectroscopy, fourier transform infrared spectroscopy, X-ray diffraction, scanning electronmicroscopy, energy dispersive X-ray, and transmission electron microscope. Silver nanoparticles possess high antibacterial activity since silver indifferent forms has been extensively used as a medicine for curing diseases and promote wound healing. Silver nanoparticles have high surfacespecific area, which will lead to excellent antimicrobial activity as compared with bulk metallic silver. Further, the silver nanoparticles show anticanceractivity against various cell lines such as human epidermoid larynx carcinoma (HEP-2), colon adenocarcinoma (HCT-116), breast adenocarcinoma(MCF-7), liver carcinoma (Hep-G2), and intestinal adenocarcinoma (Caco2) were well documented. This review intends to present green synthesis ofsilver nanoparticles and their application as antimicrobial and anticancer agents.Keywords: Silver nanoparticles, Bioresources, Mushroom, Antimicrobial activity, Anticancer property

Growth Performance of Staphylococcus spp. in Chromium Effluent with Various Environmental Conditions

Microorganisms and microbial products can be highly efficient to bioaccumulations of metals, especially from dilute external solutions. The emerging technologies employing microbes provides as alternative to conventional techniques towards metal removal from diverged ecosystem. Hence in the present study an attempt was made to investigate the growth pattern of metal resistant Staphylococcus spp in chromium electroplating effluent with various environmental conditions. Metal resistant Staphylococcus spp was isolated from electroplating effluent soil sediments and the strain was confirmed by morphological and biochemical characteristics. Further, the study characterized the growth of Staphylococcus spp in chromium containing electroplating effluents with various concentration (15%, 20% & 25%) and with different pH (pH 5, pH 7 & pH 9), and various temperature (20°C, 30°C & 40°C) conditions, the results revealed that Staphylococcus spp shown the better growth in 20% chromium containing electroplating effluents with pH 7 at 30°C.
