    Understanding the functional attributes of different microbial enzymes in bioremediation
    (University of North Bengal, 2020-03) Malakar, Neha; Mitra, Sreya; Toppo, Prabha; Mathur, Piyush
    Bioremediation uses biological organisms and their metabolic processes in order to degrade contaminants present in water, soil etc. Microbes have the vast potential are the major resource for bioprocess of using microbial enzymes reduces the toxicity of pollutants caused by the waste materials like pesticides, insecticides, plastics, other hydrocarbon-containing substances and obtain novel useful substances for mankind and the environment. Enzymes produced by bacteria, fungi, plants play a key role in the biodegradation of toxic organic compounds. The purpose of bioremediation processes that will an eco-friendly and cost-effective mechanism. The aim is to develop an advanced technique in bioprocesses that will help to minimize toxin risk and thereby acquire new, usable substances. Some of the bioremediation-related compounds like oxidoreductases hydrolases, dioxygenase, peroxidases, and laccase are most widely considered. The aim of the review is to express the role of microbial enzymes on the bioremediation of toxic, hazardous environmental pollutants.

    Bioprospecting for microbial endophytes and their natural products
    (University of North Bengal, 2015-03) Jha, D.K.
    Endophytes are microorganisms that reside asymptomatically in internal tissues of all higher plants. There is growing interest amongst the researches about this group of organisms because these are promising sources of biologically active agents. They are potential sources of novel natural products for scope of utilization in the pharmaceutical industry, agriculture, and in environmental applications. Many researches have proven that endophyte in new and potential source of novel natural products for exploitation in modern medicine, agriculture and industry. So far, a great number of novel natural products possessing antimicrobial activities have been isolated from endophytes. It is believed that screening for antimicrobial compounds from endophytes is a promising way to overcome the increasing threat of drug resistant strains of human and plant pathogen. Antimicrobial metabolites isolated from endophytes belong to diverse structural classes, including: alkaloids, peptides, steroids, terpenoids, phenols, quinones, and flavonoids. These would provide the opportunity to utilize endophytes as a new source for production of antibiotics.
