Forskningsoutput: Tidskriftsbidrag av R Koppram · 2014 · Citerat av 71 — Combined substrate, enzyme and yeast feed in simultaneous saccharification and fermentation allow bioethanol production from pretreated spruce biomass at Multifeed simultaneous saccharification and fermentation enables high gravity submerged fermentation of lignocellulose. Konferensbidrag (offentliggjort, men ej A novel method of bioethanol production from lignocellulosic biomass “Simultaneous Saccharification Filtration and Fermentation (SSFF)” was developed and (SSF), non-isothermal simultaneous saccharification and fermentation (NSSF), Enzymatic hydrolysis, Ethanol, Fermentation, Lignocellulosic materials The simultaneous saccharification and fermentation (SSF) of sweet sorghum carbohydrates to ethanol by Fusarium oxysporum F3 alone or in mixed culture with Simultaneous saccharification and co-fermentation (SSCF) has been recognized as a feasible option for ethanol production from xylose-rich lignocellulosic materials. A combination of enzyme and substrate feeding was shown to enhance xylose uptake by yeast and increase overall ethanol yield in SSCF.

This process is based on the use of an enzymatic complex to hydrolyze cellulose and obtain sugars. The liquefied mash then goes into the saccharification and fermentation step. Saccharification breaks down shorter glucose chains (dextrins) into fermentable sugars. A glucoamylase enzyme is used to hydrolyze liquified starch to single glucose molecules, where yeast then converts glucose to ethanol and CO2 during fermentation. Background: Simultaneous saccharification and fermentation (SSF) is a promising process for bioconversion of lignocellulosic biomass.
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.
Simultaneous Saccharification, Filtration and Fermentation
2016-09-05 The combination of saccharification and fermentation can decrease the number of vessels needed and thereby reduce the initial costs. Using the SSF process eliminates the inhibition of saccharifying enzyme by sugars because the resulting sugars are immediately converted to ethanol by fermentation microorganisms (see Box 10.1 ).

After pretreatment, solids of rye straw were suspended in Na citrate buffer or post‐pretreatment liquids (prehydrolysates) containing sugars liberated after hemicellulose hydrolysis. Synergistic saccharification, and direct fermentation to ethanol, of amorphous cellulose by use of an engineered yeast strain codisplaying three types of cellulolytic enzyme Abstract. We have investigated the relative performance of the two enzymes, α‐amylase and amyloglucosidase, and two microbial strains, Zymomonas mobilis AX101 and 8b, for saccharification and fermentation of sweet potato.Modified Michaelis–Menten and Monod‐type mathematical models were developed and verified with experimental results for saccharification using amyloglucosidase … PDF | On Jan 1, 2020, Venkata Nadh Ratnakaram and others published Simultaneous Saccharification and Fermentation of Watermelon Waste for Ethanol Production | Find, read and cite all the research Simultaneous saccharification and fermentation (SSF) and pre-hydrolysis with SSF (PSSF) were used to produce hydrogen from the biomass of Chlorella sp. SSF was conducted using an enzyme mixture consisting of 80 filter paper unit (FPU) g-biomass−1 of cellulase, 92 U g-biomass−1 of amylase, and 120 U g-biomass−1 of glucoamylase at 35 °C for 108 h. Detoxification of the acid‐ and enzyme‐treated rice hull hydrolyzate by overliming (pH 10.5, 90 °C, 30 min) reduced the time required for maximum ethanol production (17 ± 0.2 g from 42.0 ± 0.7 g sugars per L) by the E. coli strain from 64 to 39 h in the case of separate hydrolysis and fermentation and increased the maximum ethanol yield (per L) from 7.1 ± 2.3 g in 140 h to 9.1 ± 0.7 g in 112 h in the case of simultaneous saccharification and fermentation. 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.
Pretreated cogongrass was simultaneously saccharified and fermented by using the commercial cellulase Accellerase 1500 (Genencor, USA) and Ethanol Red TM dry Saccharomyces cerevisiae yeast (Fermentis, France), respectively. Simultaneous saccharification and fermentation (SSF) by Clostridium acetobutyli-cum ATCC 824 was conducted to produce biobutanol from sago hampas. Sago ham-pas is a waste generated from the processing of sago starch. This waste is composed
saccharification and fermentation (SSF) was introduced which involves co-culturing of an amylase producing organism and a fermenting organism in the same vessel . These organisms would synergistically utilize the substrates for food and, in the process, yield ethanol , . The observation

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-Fermentation process was developed. Saccharification and fermentation are done simultaneously in order to decrease enzymatic end-product inhibition thus producing a better yield.

In the dry‐grind fuel ethanol industry, coproducts such as distillers' dried grains and carbon dioxide are obtained after liquefaction (conversion of starch to soluble form), saccharification (conversion of soluble starch to glucose), and fermentation (conversion of glucose to ethanol). The objective of this work was to optimize the enzymatic hydrolysis of the cellulose fraction of cellulignin, and to study its fermentation to ethanol using Saccharomyces cerevisiae. Cellulose conversion was optimized using response surface methods with pH, enzyme loading, solid percentage, and temperature as factor variables.
