“…The results are also in conformity with those of earlier study report [12] that is highest enzyme activity (1845U/g) on wheat bran when used mutant strain A.niger GCBMX-45 for enhanced xylanase production. Similar earlier work [13] was conducted to find out the potential of A. niger A3 for the production of xylanase in solid state fermentation. condition for xylanase production [7].…”

In the present study an attempt was made to optimize the cultural conditions using agricultural substrate for xylanase production by Aspergillus flavus in solid state fermentation process. The optimization of cultural conditions such as optimal temperature, pH and inoculam size was studied and best choice for agricultural substrate among wheat bran, wheat bran, and soya bran substrates in solid state fermentation for xylanase production has been investigated. Among three different agricultural substrates rice bran shows the maximum enzyme activity of 162.0±3.0 unit /ml. The enzyme assay was carried out at different temperatures and pH which shows maximum enzyme activity of 172.0±4.1 units /ml in wheat bran at 32 0 C and pH 8 produce the maximum enzyme activity in soya bran 183.0±5.1 units /ml respectively. Optimization of inoculum size for xylanase production shows 140 spores/ ml that is 184.0±2.8 units /ml in wheat bran used as the substrate.With this studies the optimized culture medium for the production of the enzyme and to get the maximum enzymatic activity with the optimized temperature32°C, pH 8, substrate wheat bran and the inoculmn size of 140 spores/ml shows the maximum enzyme activity of 190±3.1units /ml.

Abstract:The robustness of A. awamori and A. oryzae as enzyme producers is exploited in fungal fermentation on agricultural solid waste. High-level production of extracellular glucoamylase, protease, cellulase and xylanase has been achieved. Three different types of 'waste' solids (wheat bran, soybean hulls and rapeseed meal) have been used in studies of solid state fermentation (SSF). The enzymes could be produced in significant levels by continuously supplying oxygen (O 2 ) through the tray system known as "closed" and "opened" tray systems. A perforated tray system was developed in this study that permits direct access to O 2 . Testing the tray system with different perforated mesh aperture sizes in this study did not yield different results in growth performance of A. awamori and A. oryzae. A. awamori and A. oryzae can be very versatile in producing various enzymes with different substrates with different starch, protein, hemicellulose and cellulose contents. These studies indicate that A. awamori is more suitable for the efficient production of multiple enzymes in the closed system including xylanase and cellulase, while the production of glucoamylase and protease is superior in the opened system. A. oryzae is more suitable for the efficient production of protease and cellulase in the closed system, while the production of protease is more favourable the opened system. A. awamori efficiently consumed starch in wheat bran medium and produced very high glucoamylase activity, and after that, the fungus efficiently produced other enzymes to degrade other complex nutrients such as protein, hemicellulose and cellulose. Meanwhile, A. oryzae efficiently consumed protein in rapeseed meal and produced very high protease activity. The ability of both filamentous fungi, to convert biomass through SSF bioconversion will have a great impact on food and agro-industry in every aspect of life from food and medicine to fuel.

“…This is an important way, in developed countries, of dietary changes for the partial substitution of animal protein with plant protein. Fermentation with Aspergillus niger, a filamentous fungi, have been studied for citric acid 4 , xylanolytic enzyme 5,6 , pectolytic enzyme 7,8 , β-glucosidase 9,10 , alpha and gluco-amylase 11,12,13 , and nucleic acid related substances productions 14 . The study of fungal growth in SSF shows advantages over submerged cultures, because this is a natural environment for filamentous fungi 15 .…”

Recebido em 4/1/00; aceito em 11/10/00Agricultural wastes from cactus Cereus peruvianus and Opuntia ficus indica were investigated for protein production by solid substrate fermentation. Firstly, the polyelectrolytes were extracted and used in water cleaning as auxiliary of flocculation and coagulation. The remaining fibrous material and peels were used as substrate for fermentation with Aspergillus niger. Glucoamylase and cellulase were the main enzymes produced. Amino acids were determined by HPLC and protein by Lowry's method. After 120 hours of fermentation the protein increased by 12.8%. Aspartic acid (1.27%), threonine (0.97%), glutamic acid (0.88%), valine (0.70%), serine (0.68%), arginine (0.82%), and phenylalanine (0.51%) were the principal amino acids produced.
