Bio-ethanol Production from Bamboo Residues with Lignocellulose Fractionation Technology (LFT) and Separate Hydrolysis Fermentation (SHF) by Zymomonas Mobilis

چکیده
Combined lignocellulose fractionation technology (LFT) and separate hydrolysis fermentation (SHF) for the production of ethanol from bamboo residues and corn stover were investigated by using Zymomonas mobilis. In this process, the highest ethanol concentration reached 4.72 g/l from pretreated bamboo shoots shell fiber (BSSF) and the ethanol yield were 55.82% of the theoretical within 24 h at 30°C. However, during the SHF process at different conditions, about 25.0%-40.0% of the reducing sugar produced by enzymatic hydrolysis remained in the ferment medium. These results indicated that the combinated process of LFT and SHF is a useful method for lignocellulosic-to-ethanol. Bamboo residues are also not only an attractive feedstock for ethanol production like corn stover, but better, based on these results.

Evaluation of Ethanol Production from Tannin-Reduced Carob Pod Extracts by Zymamonas Mobilis
Regarding some reported antimicrobial properties of tannins; Zymomonas mobilis was used to obtain ethanol from tannin-reduced carob pod extract (TR-CPE). Culture of 50 mL volume containing 7.5 g sugar at pH 5.5 and 0.03 g bacterial inoculums with shaking at 80 rpm was used. Using response surface methodology (RSM), the maximum ethanol concentration of 5.34 % w/v (higher than that reported earli...
متن کاملEnhancement of furan aldehydes conversion in Zymomonas mobilis by elevating dehydrogenase activity and cofactor regeneration
BACKGROUND Furfural and 5-hydroxymethylfurfural (HMF) are the two major furan aldehyde inhibitors generated from lignocellulose dilute acid pretreatment which significantly inhibit subsequent microbial cell growth and ethanol fermentation. Zymomonas mobilis is an important strain for cellulosic ethanol fermentation but can be severely inhibited by furfural and (or) HMF. Previous study showed th...
متن کاملInfluence of fermentation conditions on levan production by Zymomonas mobilis CT2
Zymomonas mobilis produces two extracellular sucrases namely levansucrase (sac B) and sucrase (sac C). A mutant strain of Z. mobilis CT2 defective in sucrase sac C, constructed earlier by gene disruption, produced higher levels of levan (27.2 g L) than the parent strain B14023 (15.4 g L) from 200 g L of sucrose at 25°C and pH 5.0. Increasing fermentation temperature from 25 to 35°C enhanced eth...

Glycyrrhiza glabra residue (GGR) was efficiently subjected to concentrated phosphoric acid (PA) pretreatment with/without surfactant assistance, and promising results were obtained following separate enzymatic hydrolysis and fermentation (SHF) of the biomass. Pretreatment was carried out using 85 % PA either at 50 or 85 °C with 12.5 % solid loading for 30 min. In parallel experiments, ...
متن کاملSecretive expression of heterologous β-glucosidase in Zymomonas mobilis
Background: Zymomonas mobilis is an efficient ethanol fermentation strain, but its narrow substrate range limits its fermentation in lignocellulose hydrolysate. As a potential consolidated bioprocessing (CBP) stain for bioethanol production, the ability of cellulose utilization was necessary. In this study, extracellular expression of β-glucosidase on Z. mobilis was studied as the first step fo...
