Fungal strains are cultivated in tissue culture plates containing 14C-ring-labeled dehydrogenation polymerizate (DHP) (synthetic lignin). MATERIAL AND METHODS Collection of sample: The sediment samples were collected from Marak-kanam saltpan environments (Latitude 120 14’.12” N, Longitude 0790 56’.28” E). The aim of this work was to evaluate protease production by different bacterial isolated from marine. And P1 were characterized as Gram-negative, rod shaped bacteria, motile, Screening of Metabolites for Isolation of Microorganisms: The microorganisms can be tested directly for the product formation, and isolated. The screenings and assays basically rely on color changes of substrates, visible substrate degradation, genetic complementation, and growth dependency or on morphology studies. In modern biotechnology, enzymes or other valuable biomolecules from microbes are essential because of their applicability in challenging reactions and most often, they provide many benefits compared with conventional chemical production processes concerning enantiomeric purity, environmental sustainability, and saving of expenses. Hence the present study will be carried out to screen and produce protease enzyme by venturing into marine ecosystem In the world market, pectinases accounts for about 10% of total enzyme production.. Soils microorganisms have recently emerged as a rich source for the production of industrial enzymes so many efforts have been made to isolate pectinase producing microbes from soil. The first enzyme produced industrially was the fungal amylase Takadiastase which was employed as a pharmaceutical agent for digestive disorders. fermentation production medium, the date recorded the highest extracellular protease enzyme reached to (243 U/ml) by isolate No. The present study aimed to screening of filamentous fungi strains and growing them in batch cultures to compare their abilities in production of β-Fructofuranosidase (β-FFase) using sole carbon source as sucrose. The collected sample were Presently, work is aimed at screening and isolating cellulolytic fungi from … In fact, the water or soil samples can be directly used or suitably diluted for metabolite screening. 1.2 LITERATURE REVIEW. The production of enzymes is central to the modern biotechnology industry. C43 isolate was found to produce significantly (P<0.05) high phytase activity and was identified based on preliminary morphological and biochemical tests as Bacillus sp. In our previous studies, a total of 89 microorganisms, including Protease production is an inherent capacity of all microorganisms and a large number of microbes belonging to bacteria, fungi, yeast and actinomycete are known to produce proteases.

Chitosan has immense potential especially in the field of agriculture, food and pharmaceuticals. BACKGROUND: The use of agroindustrial residues as substrate for inulinase bio‐production is a good choice to reduce production costs, since enzyme activity will be improved and the downstream step of the process will be viable technically and economically. Although a large number of microorganisms are capable of degrading cellulose, only a few of these microorganisms produce significant quantities of cell-free enzymes capable of completely hydrolysing crystalline cellulose in vitro. Isolation and screening of actinomycetes from marine samples for enzyme production Lekshmi, M., Ayona Jayadev and Navami, S.S* Abstract- Many of the ecological factors of the marine environment were helpful in developing a strategy for discovering useful bioactive agents from marine microorganisms. Sp The plate was made up of fibrinogen solution (2.5 ml of 1.2% fibrinogen) in 0.1 M sodium phosphate buffer, pH 7.4), 10 U thrombin and 1% agarose. During primary and secondary screening iodine solution, Nutrient Agar Medium, Starch Agar Medium were used. This enzyme hydrolyses acetamido groups of N-acetyl glucosamine in chitin. Alginate lyase is a biocatalyst that degrades alginate to produce oligosaccharides, which have many bioactive functions and could be used as renewable biofuels. Microorganisms have been exposed to a myriad of substrates and environmental conditions throughout evolution resulting in countless metabolites and enzymatic activities. Fungi are the best puissant basis of lignin-degrading enzymes. enzymes, accounting for more than 65% of the industrial enzyme market [1,2,7] of these; alkaline protease accounts for 30% of the world’s total enzyme production and applications in detergent formulations alone make up to 89% of total sales. Enzymes produced by indigenous yeasts associated with grapes and juice might be harnessed to catalyse desired biotransformations during wine fermentation. ... Optimization of enzyme production Agar plates can be used for screening metabolites formed from the microorganisms. In fact, only a few hundred species are important for industrial use. For the screening of microorganisms producing β-galactosidase, lactose medium (0.5% lactose, 0.5% peptone, 0.3% beef extract, agar 1.5%, pH 6.5) was used. Agar plates are treated with casein - a protein that makes it cloudy. 1.2 LITERATURE REVIEW. Production conditions were optimized (temperature, pH) to achieve high enzyme production and better enzyme activity. The saprophytic fungi make these enzymes to break down the lignin polymer. The production of the enzyme protein can be conducted using such organisms due to the possibility of mass cultivation, mild fermentation conditions as well as the easy elaboration of optimized production systems.
