Solid-state fermentation conditions were investigated for cellulase production by marine Aspergillus ZJUBE-1 using crop straw as the main material. When Aspergillus ZJUBE-1 was grown under the condition: ratio of rice straw to wheat bran was 1:1, the ratio of material to liquid was 1:2, the ratio of nitrogen and carbon was 5.6%, NaCl was 2.4~4.0%, temperature at 37 °C, the maximum CMCase activi...

The rising demand for bioethanol, the most common alternative to petroleum-derived fuel used worldwide, has encouraged a feedstock shift to non-food crops to reduce the competition for resources between food and energy production. Sweet sorghum has become one of the most promising non-food energy crops because of its high output and strong adaptive ability. However, the means by which sweet sor...

Dai X.-J., Liu M.-Q., Jin H.-X., Jing M.-Y. (2011): Optimisation of solid-state fermentation of Aspergillus niger JL-15 for xylanase production and xylooligosaccharides preparation. Czech J. Food Sci., 29: 557–567. The production of xylanase (XylA) by Aspergillus niger JL-15 in solid-state fermentation (SSF) on orange peel was optimised by the response surface methodology (RSM). The results rev...

Modified solid-state fermentation (MSSF) of tannin-rich substrates for production of tannase and gallic acid was carried out using fungal co-cultures. Tannin acyl hydrolase or tannase is an enzyme produced extracellularly in solid state fermentation by various fungi. The solid-state fermentation offers a number of advantages over submerged and liquid conventional fermentation for the enzyme pro...

BACKGROUND: An inexpensive and readily available agroindustrial substrate such as rice bran can be used to produce cheap commercial enzymes by solid-state fermentation. This work investigates the production of food-grade proteases by solid-state fermentation using readily available Thai rice bran. RESULTS: A local strain of Aspergillus oryzae (Ozykat-1) was used to produce proteases. Rice bran ...

Introduction Acetobacter pasteurianus is among the major bacteria responsible for acetic fermentation and gives the characteristic taste of vinegar, can be found as a contaminant of wine production industry. In industrial fermentation is frequent contamination by lactic acid bacteria such as Lactobacillus fermentum that competes with the yeast for nutrients and inhibiting their growth, slow the...

The potential role of a new energy efficient fermentation technology has been receiving growing attention in past 4 decades. Carboxylic acids such as propionic acid, lactic acid, citric acid, tartaric acid, itaconic acid, butyric acid and nicotinic acid etc. have been used as the most efficient fermentation chemicals. This paper presents a state-of-art review on the development of the separatio...

Functional properties and antioxidative activity of a protein hydrolysate prepared from Acanthogobius hasta processing by-product protein during solid-state fermentation with Aspergillus oryzae were investigated. Overall, protease activity increased with the degree of hydrolysis (DH) decreased during solid-state fermentation. All the protein hydrolysate had excellent solubility, possessed inter...

Cellulase and xylanase production from rice straw using M.thermophila SH1 was assessed. The waste was dried, grinded to mesh size of 2.0mm and microwave pretreated. The powdered waste was than used as a substrate. Fermentation was carried out in flasks containing pretreated and untreated rice straw, vogel;s medium, cultured at 50C initially for 8 days to verify cellulase production and for 5 da...

Fermentation has been widely used for the production of a wide variety of substances that are highly beneficial to individuals and industry. Over the years, fermentation techniques have gained immense importance due to their economic and environmental advantages. Ancient techniques have been further modified and refined to maximize productivity. This has also involved the development of new mac...
