av G Eriksson · Citerat av 6 — Since heat and electricity production using the hydrolysis/fermentation One enzymatic process is simultaneous saccharification and fermentation (SSF).

The SSF of 10.0% (w/v) H2O2-MnSO4 treated straw yielded maximum ethanol (2.9%, w/v) after 72 h at 40 degrees C. As a consequence of the well-balanced cellulase production by mixed fungal culture, the supplementation of cellobiase or xylanase was not necessary in the simultaneous saccharification and fermentation process. PMID: 7620815

Bioethanol fermentation in SSF mode was faster than SHF process providing the best results: ethanol concentration 18.7 g L(-1), fermentation efficiency of 66.6% and a yield of 26.6g ethanol/100 g CSEOH or 10.1 g ethanol/100 g untreated cardoon. preparations were introduced into the market. There is also a progress in fermentation technology observed. One of the most important innovations was a simultaneous sac-charification and fermentation (SSF) what allows to reduce investment costs, simplify technological operation, shorten fermentation process and increase mash gravity [Roy Production of lactic acid from paper sludge has been performed by simultaneous saccharification and fermentation (SSF).

MOFs … The saccharification was increased to 94.88% by removal of the hydrolysate after 24h by using a two-step hydrolysis. Significant lactic acid production (27.8mg/mL) was obtained by separate saccharification and fermentation after 72h of incubation. But, was minimized when saccharification and conversion of non-edible lignocellulosic biomass fermentation processes are employed constituted by cellulose (40-50%), hemicelluloses simultaneously using co-culture of Aspergillus (20-30%), and lignin (20-30%) into ethanol is more niger or Aspergillus oryzae and yeast 10, 15.

Simultaneous saccharification and fermentation SSF is a process in which sugars from the liquefied substrates are saccharified and fermented in a single fermenter using enzyme and yeast. The drawback of SSF of cellulose using enzymes is feedback inhibition by the product. The bioconversion of cellulosic wastes into high-value bio-products by saccharification and fermentation processes is an important step that can reduce the environmental pollution caused by agricultural wastes. Saccharification of biomass to fermentable sugar is a major constraint for bioethanol production due to high cost of enzyme production and complications associated with the removal of hearse acid, alkali and salts formed after neutralization. Separate saccharification and fermentation (SSF), simultaneous enzymatic hydrolysis and fermentation (SEHF), and consolidated bioprocessing (CBP) are the common approaches for ethanol fermentation. In SSF, optimized temperature can be used in the saccharification process to maximize the enzymatic activity, thereby effectively producing simple sugars. Here, Metal-Organic Frameworks (MOFs) coupling simultaneous saccharification and fermentation for butyric acid production using rice straw was constructed.

This research shows the effect of dilute acid pretreatment with various sulfuric acid concentrations (0.5–2.0% [wt/vol]) on enzymatic saccharification and fermentation yield of rye straw. After pretreatment, solids of rye straw were suspended in Na citrate buffer or post‐pretreatment liquids (prehydrolysates) containing sugars liberated after hemicellulose hydrolysis.
