In the present investigation, an attempt was made to isolate endophytic fungi from rice plant (Oryza sativa L.). A total of 48 fungi were isolated from 288 segments, from 4 varieties (Gitanjali, Hiranyamayee, Khandagiri and Lalat) of rice plant (Oryza sativa L). The coloniczation frequency of the endophytic fungi were observed to be 16.87% and 16.40% in leaf and stem respectively.

The process parameters influencing the production of extracellular laccases by Streptomyces lavendulae were optimized in submerged fermentation. It was made to screen, enhance and production of laccase enzyme produced by the consortium of laccase producing Streptomyces lavendulae. To date, laccases connect mostly been independently and characterized from flora and fauna of fungi and unaided fungal laccases are used currently in biotechnological applications

Production and optimization of endoglucanase by Aspergillus sp., Trichoderma sp. and Penicillium sp.
Endoglucanase is one of the most important industrial enzymes. In the present study, three different fungi Aspergillus sp., Trichoderma sp. and Penicillium sp. were isolation for endoglucanase production from soil samples on PDA plate. All three fungus processed by submerged fermentation and solid state fermentation for its enzymatic activity. Aspergillus sp., showed highest enzymatic activity in both type of fermentation.

Twenty Five lignolytic fungi were isolated from decaying wood samples and were screened for the laccase production using guaiacol and ABTS as indicator compounds. The positive isolates were confirmed for the presence of laccase using Azure B and quantitative enzyme assay in presence of catalase using ABTS as substrate. Further laccase producing capacity of fungus was estimated in seven different media where Czapex Dox medium showed highest enzymatic activity of 17.2 U/ml.

The objective of this research was to determine the significant parameters for the production of α-L-rhamnosidase by Aspergillus flavus in submerged fermentation. Five factors Viz. inducer concentration (naringin), incubation days, temperature, pH and metal ion at two levels were selected with orthogonal array layout of L16 (25 ). The experimental result indicate that inducer concentration (0.5% naringin), incubation days (7), temperature (28 0C), and pH (6.

In the current context of eco-pollution, the substitute of conventional plastics with bioplastics is a big confront. On account of that, a non-growth associated PHB production study was conducted using Zobellella species under submerged fermentation process. As a result, Zobellella species showed the ability to accumulate 2.2g/L of PHB at pH 8. 0, temperature 37oC, salt concentration 2% in modified growth medium containing vitamins. Then, primary structural characterization of extracted polymer was conducted by FTIR analysis. The high intense peak was obtained at 1720.
