The results showed that 67%, 56%, 49%, 39% and 25% of the endophytic fungi could produce lipase, cellulase, pectinase, protease and amylase enzymes, respectively (Table 2). The production of ligninolytic enzymes from various microbial sources has been well known and documented. Secondary Screening of Microorganisms: Primary screening helps in the detection and isolation of microorganisms from the natural substrates that can be used for industrial fermentations for the production of compounds of human utility, but it cannot give the details of production potential or yield of the organism. The aim of this work was to evaluate protease production by different bacterial isolated from marine. known lignin degrading enzymes have been classified from fungi, typically form those belonging to white-rot basidiomycetes. The enzymes produced by such microorganisms mainly include lignin peroxidase (LiP), manganese peroxidase (MnP) and laccases (Gassara et al., 2010). (Plants, Animals, Fingi, Bacteria and Viruses). The amount and range of enzymes produced varied with … Microorganisms elaborate a large array of proteases, which are intracellular and/or A total of 13 Actinomycete strains were isolated from 70 soil samples collected from five locations across the Jeddah Province, while the other two locations located in Baljurashi The saprophytic fungi make these enzymes to break down the lignin polymer. Colonies growing on the surface of a solid medium capable of extracellular enzyme synthesis are identified by reacting the enzyme or enzyme product surrounding each cology with an analytically indicatable reagent which does not adversely effect the viability of said colonies. Similarly, bacteria can be screened for protease production. ey words: Protease, extracellular, enzyme, screening, isolations. investigated for phytase production in submerged fermentation. Production conditions were optimized (temperature, pH) to achieve high enzyme production and better enzyme activity. 3.1 Isolation and screening of lipase producing bacteria: A total of 158 colonies were selected and isolated from the 11 samples.
