    The rhizosphere is the most active region of soil where plants and microorganisms live in close association and exhibit complex interactions. In the present study, rhizospheric soil samples were collected from bamboo and banana growing well in University of North Bengal campus. Cellulolytic and amylolytic bacteria were isolated from these samples through serial dilution technique and were identified on the basis of morphological and biochemical characteristics. The study showed presence of four isolates mostly from genera Bacillus sp. from rhizosphere of bamboo capable of degrading cellulose while five isolates (Rummeliibacillus sp., Lysinibacillus, Brevibacillus, and Bacillus) from rhizosphere of banana and degrade starch respectively. The study although preliminary but will prove valuable for the extraction of these enzymes from these rhizospheric isolates and will be highly appreciated for their application in biotechnology sector.

    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.
