Clostridium kluyveri is unique among the clostridia; it grows anaerobically on ethanol and acetate as sole energy sources. Fermentation products are butyrate, caproate, H2. We report here genome sequence of C. kluyveri, which revealed new insights into metabolic capabilities this well studied organism. A membrane-bound energy-converting NADH:ferredoxin oxidoreductase (RnfCDGEAB) a cytoplasmic butyryl-CoA dehydrogenase complex (Bcd/EtfAB) coupling reduction crotonyl-CoA to with ferredoxin...
Cell extracts of butyrate-forming clostridia have been shown to catalyze acetyl-coenzyme A (acetyl-CoA)- and ferredoxin-dependent formation H2 from NADH. It has proposed that these bacteria contain an NADH:ferredoxin oxidoreductase which is allosterically regulated by acetyl-CoA. We report here ferredoxin reduction with NADH in cell Clostridium kluyveri catalyzed the butyryl-CoA dehydrogenase/Etf complex acetyl-CoA dependence previously observed due fact via crotonyl-CoA butyryl-CoA. The...
Polymer-stabilized tetragonal ZrO(2) nanopowders with average size of ca. 2.0 nm have been prepared by microwave heating in an aqueous solution containing Zr(NO(3))(4) x 5H(2)O, PVA, and NaOH. The photoluminescence the synthesized fine particles has investigated.
The increasing energy demand has pushed oil and gas exploration development limits to extremely challenging harsher HTHP (High Temperature High Pressure) environments. Maintaining wellbore integrity in these environments, particularly HPHT reservoirs with corrosive gases, presents a significant challenge. Robust risk evaluation mitigation strategies are required address reservoirs' safety, economic, environmental uncertainties. This study investigates chemo-mechanical properties degradations...
Cellulosic bioethanol production generally has a higher operating cost due to relatively expensive pretreatment strategies and low efficiency of enzymatic hydrolysis. The other high-value chemicals such as xylitol phenylacetylcarbinol (PAC) is, thus, necessary offset the promote economic viability. optimal conditions diluted sulfuric acid under boiling water at 95°C subsequent hydrolysis steps for sugarcane bagasse (SCB), rice straw (RS), corn cob (CC) were optimized using response surface...
Abstract Achieving fast conversion and precise regulation of product selectivity in electrochemical CO 2 reduction reaction (CO RR) remains a challenge. The space confinement effect provides theoretical basis for the design catalysts different morphology sizes reveals physical phenomena caused by electrons other particles at nanoscale. In this work, semi‐confinement concept is introduced mesoporous silica nanosphere supported Cu catalyst (Cu‐MSN) prepared as typical example to realize RR...
To determine whether corncob residue (CCR) could be a good substrate for butanol production.In this study, Ca(OH)₂ detoxification technique was used to remove inhibitors of lignocellulose enzymatic hydrolysis. During fermentation untreated hydrolysate (CCRH) by Clostridium beijerinckii NCIMB 8052, cell growth inhibited and only 3·8 g l⁻¹ acetone, ethanol (ABE) produced. After pretreatment with Ca(OH)₂, hydrolysis CCR resulted in 49·3 total sugars, about twofold that one. In the...
Fucoxanthin is a natural pigment found in microalgae, especially diatoms and Chrysophyta. Recently, it has been shown to have anti-inflammatory, anti-tumor, anti-obesityactivity humans. Phaeodactylum tricornutum diatom with high economic potential due its content of fucoxanthin eicosapentaenoic acid. In order improve production, physical chemical mutagenesis could be applied generate mutants. An accurate rapid method assess the prerequisite for high-throughput screen this work, P. was...
Brown algae are promising feedstocks for biofuel production with inherent advantages of no structural lignin, high growth rate, and competition land fresh water. However, it is difficult one microorganism to convert all components brown different oxidoreduction potentials ethanol. Defluviitalea phaphyphila Alg1 the first characterized thermophilic bacterium capable direct utilization algae.Defluviitalea can simultaneously utilize mannitol, glucose, alginate produce ethanol, ethanol yields...
Alginate is a polymer containing two uronic acid epimers, β-d-mannuronate (M) and α-l-guluronate (G), major component of brown seaweed that depolymerized by alginate lyases. These enzymes have diverse specificity, cleaving the chain with endo- or exotype activity differential selectivity for sequence M G at cleavage site. Dp0100 201-kDa multimodular, broad-specificity endotype lyase from marine thermophile Defluviitalea phaphyphila, which uses algae as carbon source, converting it to...
Both CO and H2 can be utilized as energy sources during the autotrophic growth of Clostridium ljungdahlii. In principle, is a more energetically thermodynamically favorable source for gas fermentation in comparison to H2. Therefore, metabolism may vary under different sources. this study, C. ljungdahlii was fed with and/or CO2/H2 at pH 6.0 pressure 0.1 MPa. primarily produced acetate presence an source, but alcohols same conditions. A key enzyme activity assay, metabolic flux analysis,...
This article focuses on the background and current situation of various levels biogas generation in mainland China. These are categorised as rural household, agricultural engineering industry-based generations. To analyse forecast China's generation, Hubbert model was discussed for Chinese provinces. initially applied to petroleum research industry can be implemented prediction. The results validate that total may not achieved coming years because low household production thus contradicts...
The dibenzothiophene (DBT) desulfurization pathway of a facultative thermophilic bacterium Mycobacterium sp. X7B was investigated. Metabolites were identified by gas chromatography-mass spectrometry, and the results showed that 2-hydroxybiphenyl, end product previously reported sulfur-specific (also called 4S pathway), further converted to 2-methoxybiphenyl. This is first strain possess this ability therefore, an extended determined. In addition, DBT-desulfurizing able grow on DBT...
ABSTRACT A carbazole-utilizing bacterium was isolated by enrichment from petroleum-contaminated soil. The isolate, designated Sphingomonas sp. strain XLDN2-5, could utilize carbazole (CA) as the sole source of carbon, nitrogen, and energy. Washed cells XLDN2-5 were shown to be capable degrading dibenzofuran (DBF) dibenzothiophene (DBT). Examination metabolites suggested that degraded DBF 2-hydroxy-6-(2-hydroxyphenyl)-6-oxo-2,4-hexadienic acid subsequently salicylic through angular...
Xylanases are crucial for lignocellulosic biomass deconstruction and generally contain noncatalytic carbohydrate-binding modules (CBMs) accessing recalcitrant polymers. Understanding how multimodular enzymes assemble can benefit protein engineering by aiming at accommodating various environmental conditions. Two xylanases, XynA XynB, which belong to glycoside hydrolase families 11 (GH11) GH10, respectively, have been identified from Caldicellulosiruptor sp. strain F32. In this study, both...
