Bushnell Haas medium (BHM) was used for isolation of cellulose hydrolytic bacteria after amendment with carboxymethylcellulose (CMC) as the sole carbon source. 2.3. Isolation and screening of cellulases producing bacteria. Ten grams of each soil or ward poultry sample were diluted with 90 ml saline solution in Erlenmeyer flasks. This method was first described by Hungate in 1947 and is still extensively used today, and widely regarded as the best method for the isolation of obligate anaerobic cellulose-degrading bacteria and fungi that cannot be cultivated on solid medium in Petri dishes. The use of microorganisms for the production of enzymes offers a promising approach for its large scale production and as a possible food supplement or in pharmaceutical industry. Key words: Cellulase producing bacteria, Cellulase, Coir wastes, Saw dust, Cow dung, Partial purification [I] INTRODUCTION Cellulose is the most abundant biomass on the This study presents the production of bacterial cellulose (BC) by a bacterium isolated from a rotten fruit and its process optimization. Here, isolation and screening of potent cellulose producers were carried out from different natural sources, viz., soil, rotten fruits, and vegetables and vinegar. Cellulose feeding organisms like termite, caterpillar, bookworm, and snail were collected for isolation of cellulose-degrading bacteria from woody habitats. Guts of the collected organism were separately crushed in 0.9% saline solution under sterile condition.

Microbial cellulose, an exopolysaccharide produced by bacteria, has unique structural and mechanical properties and is highly pure compared to plant cellulose. Present study represents isolation, identification, and screening of cellulose producing

Isolation and screening of cellulases producing bacteria. Ten grams of each soil or ward poultry sample were diluted with 90 ml saline solution in Erlenmeyer flasks. Cellulose producing bacterial strain was isolated from citrus fruit juice fungus. The isolated strain was identified as Gluconacetobacter sp. gel_SEA623-2 based on several morphological characteristics, biochemical tests, and 16S rRNA conducted. Culture conditions for bacterial cellulose production by SEA623-2 were screened in static trays. inking of paper [6]. Cellulase producing bacteria has the potential to convert cellulose into glucose. The isolation and characterization of cellulase producing bacteria will be an important aspect of biofuel research, biodegradation and bioremediation. For this project purpose, cellulose degrading bacteria was isolated from soil samples of garden, Volume 5, Issue 6 (Mar. – Apr. 2013), PP 80-89 www.iosrjournals.org “Isolation and Biochemical Characterization of Antibiotic Producing Microorganism from Waste Soil Samples of Certain Industrial areas of India” Atul Pratap Singh and Sanjay Mishra School of Biotechnology, IFTM University, Lodhipur Rajput, Delhi Road (NH-24), Moradabad But the Arising from this study, a positive correlation was observ- fact that not all the lactic acid bacteria strains in this study ed between the efficacy of bacteriocin and cellulose had inhibitory qualities against pathogenic bacteria production or bacteria growth. 1. Introduction. Plant cellulose, a major component of plant cell walls, is the most abundant and cost efficient renewable energy source, with the maximum annual output .Plant dry weight includes 35–50% cellulose, 20–35% hemicellulose, and 5–30% lignin .Cellulose has a water-insoluble highly crystalline structure, and it is surrounded by a tough lignin layer.

I. INTRODUCTION Cellulose is the primary structural component of the plant cell wall and the main product of photosynthesis in terrestrial plants [1]. Cellulose is the most abundant and common natural renewable biopolymer available on Earth [2]. A cellulase-producing bacterium was isolated from soil and identified as Cellulomonas sp. YJ5. Maximal cellulase activity was obtained after 48 h of incubation at 30 °C in a medium containing 1.0% carboxymethyl cellulose (CMC), 1.0% algae powder, 1.0% peptone, 0.24% (NH4)2SO4, 0.20% K2HPO4, and 0.03% MgSO4·7H2O. The cellulase was purified after Sephacryl S-100 chromatography twice with a are capable of degrading cellulose only few microorganisms produce significant amount of cell free enzymes capable of hydrolyzing crystalline cellulose in vitro. Among to this fungi are the main cellulose producing microorganism. Recently some bacteria and actinomycetes have also been found producing cellulases. In the present study, cellulose degrading bacteria was isolated from sheep rumen. Screening of cellulose degrading bacteria was carried out based on CMC (carboxyl methyl Cellulose) hydrolytic test which was seen as clear zone around colony as well as whatsman filter paper degradation test.

Cold-active acetyl xylan esterases allow for reduced bioreactor heating costs in bioenergy production. Here, we isolated and characterized a cold-active acetyl xylan esterase (PbAcE) from the psychrophilic soil microbe Paenibacillus sp. Alkaline saline soils, known also as “soda solonchaks”, represent a natural soda habitat which differs from soda lake sediments by higher aeration and lower humidity. The microbiology of soda soils, in contrast to the more intensively… For instance, cloning and sequencing of the various cellulolytic genes could economize the cellulase production process. Apart from that, metabolic engineering and genomics approaches have great potential for enhancing our understanding of… Technical Manual - Free download as PDF File (.pdf), Text File (.txt) or read online for free.
