High rosmarinic acid (RA) productivity has been achieved by applying jasmonic acid and yeast extract elicitors to the in vitro sprout culture of Orthosiphon aritatus (IOSC). The highest RA accumulation from three solvents was detected in IOSC after treatment with yeast extract (5 g/L). HPLC analysis clearly confirmed a drastic increase in RA subjected to yeast extract elicitation. Therefore, th...

The effect of glucose and other soluble sugars (xylose, fructose, maltose, cellobiose and lactose) in the production of amylases by Aspergillus tamarii was studied in solid state fermentation (SSF). Wheat bran solid state cultures were resistant to catabolite repression even at high concentration of glucose (10%). Results show the potential of solid state systems to overcome the adverse effects...

Lignocellulosic biomass is an economical and renewable feedstock for microbial production of bulk chemicals such as lactic acid. In many cases, simultaneous saccharification and fermentation (SSF) can achieve lower cost and higher productivity than the classical double step fermentation. Thus, in the present study, bagasse sulfite pulp was directly employed to produce lactic acid by SSF, using ...

Abstract Solid-state fermentation (SSF) may be a suitable bioprocess to produce protein-vegetal ingredients with increased nutritional and functional value. This study assessed changes in phenol content, antinutrient biomass production protein resulting from the metabolic activity of Pleurotus ostreatus , an edible fungus, lentils quinoa over 14 days SSF. The impact particle size on these param...

A major challenge to economically produce ethanol from lignocellulosic biomass is to achieve industrially relevant ethanol titers (>50 g L) to control operating and capital costs for downstream ethanol operations while maintaining high ethanol yields. However, due to reduced fermentation effectiveness at high biomass solids loadings, excessive amounts of enzymes are typically required to obtain...

Five fungal isolates were screened for the production of "-amylase using both solid-state and submerged fermentations. The best amylase producer among them, Aspergillus niger JGI 24, was selected for enzyme production by solid-state fermentation (SSF) on wheat bran. Different carbon and nitrogen supplements were used to enhance enzyme production and maximum amount of enzyme was obtained when SS...

ABSTRACT: Our target is to evaluate recent literature on chitinase production from different sources via solid-state fermentation and analyze several strategies improve fermentation. Plant pathogen biocontrol, sequential transformation of chitin into bioactive molecules such as chito-oligosaccharides N-acetylglucosamine, protoplast synthesis filamentous fungi, single-cell protein are some the a...

Mustard bran is enriched with bioactive phenolic compounds and glucosinolates, yet it underutilized as a low-value processing by-product. Here, we investigate the effects of solid-state fermentation (SSF) using various food-grade microorganisms (Aspergillus spp., Rhizopus Bacillus subtilis, Saccharomyces cerevisiae) on phytochemical composition antioxidant activities oriental mustard yellow bra...

This study evaluated steam (SE) explosion on the saccharification and simultaneous saccharification and fermentation (SSF) of waste copier paper. SE resulted in a colouration, a reduction in fibre thickness and increased water absorption. Changes in chemical composition were evident at severities greater than 4.24 resulting in a loss of xylose and the production of breakdown products known to i...

Four promising woody crops (Populus maximowiczii x nigra (NE388), P. trichocarpa x deltoides (Nll), P. tremuloides, and Sweetgum Liquidambar styraciflua) were pretreated by dilute sulfuric acid and evaluated in the simultaneous saccharification and fermentation (SSF) process for ethanol production. The yeast Saccharomyces cerevisiae was used in the fermentations alone, and in mixed cultures wit...
