The aim of the present study was to isolate and screen actinomycetes from the mangrove sediments of Nizampatnam that are potent to produce L-asparaginase, an enzyme that catalyses the hydrolysis of asparagine. A total of 31 actinomycetes strains were isolated, of which 6 strains were positive for L-asparaginase. Several physico-chemical parameters were(More)
Tuberculosis (TB), the second most deadly disease in the world is caused by Mycobacterium tuberculosis (Mtb). In the present work a unique enzyme of Mtb orotidine 5′ monophosphate decarboxylase (Mtb-OMP Decase) is selected as drug target due to its indispensible role in biosynthesis of pyrimidines. The present work is focused on understanding the structural(More)
The strain VUK-A was isolated from a sediment sample of the Coringa mangrove ecosystem was identified as Streptomyces cheonanensis based on morphological, physiological, biochemical and molecular properties. Chemical investigation of the secondary metabolites of the strain Streptomyces cheonanensis VUK-A has led to the segregation of two bioactive(More)
Chemical investigation of the actinobacterial isolate Pseudonocardia endophytica VUK-10 has led to the segregation of two known bioactive compounds, namely 4-(2-acetamidoethyl) phenyl acetate and 4-((1, 4-dioxooctahydropyrrolo [1, 2-a] pyrazin-3-yl) methyl) phenyl acetate. The strain was isolated from a sediment sample of the Nizampatnam mangrove ecosystem,(More)
Response surface methodology-based central composite design on five variables incubation time, pH, temperature, sucrose concentration, and soya peptone concentration was employed for optimization of the production of bioactive compounds by Nocardiopsis litoralis strain VSM 8. The main quadratic effects and interactions of the five variables on the(More)
Cancer is a lethal disease or a destructive phenomenon arises in human beings because of genetic factors or exposure to toxic chemicals or viral infections etc. Radio therapy is very promising in the treatment of cancer compared to other treatments. However normal cells are also destroyed along with tumor cells in this treatment. Application of nanomedicine(More)
Deep sea sediment samples of Bay of Bengal (Visakhapatnam) have been analyzed for actinomycetes as an elite source to screen for the production of bioactive metabolites. The actinomycetes strain VSM-30 has an exciting bioactivity profile and was isolated during our systemic screening of marine actinomycetes. It was identified as Streptomyces sparsus based(More)
The present study was aimed to isolate novel bioactive compounds from actinomycetes species isolated from mangrove habitats. With this connection, Pseudonocardia endophytica (VUK-10) was isolated using dilution plate technique and was examined for its secondary metabolite profiling. After successive purification and spectroscopic characterization viz.,(More)
Article history: Received on: 12/03/2016 Revised on: 14/05/2016 Accepted on: 11/06/2016 Available online: 28/07/2016 A rapid method for Pullulan-stabilized silver nanoparticles (PuAgNPs) synthesis has been developed. Different concentrations of Pullulan and Silver nitrate and effects of reaction time, pH was used to investigate the synthesis of silver(More)
The objective of this study was to determine the influence of natural biowaste substrates such as banana peel powder and coir powder at varying environmental parameters of pH (4-9) and temperature (20-50 degrees C) on the cellulase enzyme production by Aspergillus niger. The cellulase enzyme production was analyzed by measuring the amount of glucose(More)
