Production of fumaric acid from xylo-oligosaccharides manufacturing waste residue (XOR) by Rhizopus oryzae CICC 40351 was investigated in a simultaneous saccharification and fermentation (SSF) process. The fermentation conditions for SSF were optimized by an orthogonal design method to maximize the fumaric acid concentration. The highest fumaric acid concentration (12.54 g/L) was reached with a...

Lignocellulosic biomass is a promising feedstock for added value compound production in biotechnological processes such as solid-state fermentation (SSF). Although these solid materials can be directly used substrates fermentations state, pretreatment often required, especially if the microorganism selected unable to produce lignocellulosic enzymes. In present work, several strategies were appl...

Carbon, hydrogen and nitrogen analyses of banana leaf and pseudostem biomass revealed their potentiality as substrates for microorganisms. Infra-red (IR) spectra of both biomass show presence of cellulose, xylan and lignin. IR spectra of leaf and pseudostem biomass degraded in solid state fermentation (SSF) by two Pleurotus species (P. sajor-caju and P. ostreatus) for 40 days showed the utiliza...

Polygalacturonase (PG) production by Fomes sclerodermeus using solid-state fermentation (SSF) was carried out. Maximal PG activity (26 U/gdw) was obtained between days 11 and 13 at the end of exponential growth. PG activity in the crude extract was more stable at pH 5-6 and 30 degrees C and had optimum activity at pH 5 and 50 degrees C. Optimal conditions for PG extraction were: one time extrac...

This study evaluated batch fermentation modes, namely, separate hydrolysis and fermentation (SHF), Quasi-simultaneous saccharification and fermentation (Q-SSF), and simultaneous saccharification and fermentation (SSF), and fermentation conditions, i.e., enzyme and yeast loadings, nutrient supplementation and sterilization, on high titer bioethanol production from SPORL-pretreated Douglas-fir fo...

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...

context:in this review, we discuss empirical and stoichiometric models, which have been developed recently in ssf processes and the influence of environmental conditions on the variables of these models. additionally, new studies on modeling of product formation are also mentioned. evidence acquisition:solid-state fermentation (ssf) is recognized as a cheap process for producing many valuable p...

Abstract The effect of temperature, moisture content and pH during solid-state fermentation (SSF) MD2 pineapple peel with Rhizopus oryzae (MUCL 28168) was evaluated on the release bioactive compounds antioxidant capacity. Applying a central composite design, it found that temperature had significant (p < 0.05) total phenolic DPPH activity while for ABTS radical elimination activity, factor p...

Exoglucanase was produced using coffee husk, the by-product of coffee processing industries, as the sole carbon source using economical fermentation strategies like solid-state fermentation (SSF). The effects of process parameters such as pH, moisture and fermentation duration on exoglucanase synthesis was investigated using response surface methodology (RSM) based on three factors and five lev...
