Starch is considered a potential feedstock for biofuel production, particularly in light of the large-scale landfilling food waste and other starchy materials worldwide. Lipid accumulation by oleaginous yeast promising method biodiesel production from starch. However, most yeasts are grown on monosaccharides or oligosaccharides because they cannot directly utilize We therefore investigated starch-assimilation ability 1,200 yeasts. found that Cryptococcus terricola could be used fuel through...
Abstract Consolidated bioprocessing (CBP), which integrates enzyme production, saccharification and fermentation into a one-step process, is promising strategy for cost-effective ethanol production from starchy biomass. To gain insights starch-based using CBP, an extensive screening was undertaken to identify naturally occurring yeasts that produce without the addition of any amylases. Three yeast strains were capable producing significant amount ethanol. Quantitative assays revealed...
Considering the cost-effectiveness of bioethanol production, there is a need for yeast strain which can convert glucose and xylose into ethanol at elevated temperatures. We succeeded in isolating strain, designated ATY839, was capable ethanolic fermentation temperatures above those previously reported yeasts able to ferment both xylose. Strain ATY839 producing substantial amount up 37°C from 2% or The results phylogenetic analysis suggest that belongs Candida shehatae. In additional,...
Co-fermentation of glucose, xylose and L-arabinose from lignocellulosic biomass by an oleaginous yeast is anticipated as a method for biodiesel production. However, most yeasts ferment glucose first before consuming pentoses, due to repression. This preferential utilization results in delayed fermentation time lower productivity. Therefore, co-fermentation sugars could achieve cost-effective conversion microbial lipid. Comprehensive screening capable simultaneously utilizing xylose, was...
Prokaryotes that can oxidize carbon monoxide (CO oxidizers) use this gas as a source of or energy. They with dehydrogenases (CODHs): these are divided into nickel-containing CODH (Ni-CODH), which sensitive to O2, and molybdenum-containing (Mo-CODH), function aerobically. The oxygen conditions required for CO oxidizers may be limited, those have been isolated characterized so far contain either Ni- Mo-CODH. Here, we report novel oxidizer, Parageobacillus sp. G301, is capable oxidation using...
The yeast strains IPM32-16, ISM28-8sT, and IPM46-17, isolated from plant soil samples Iriomote Island, Japan, were explored in terms of lipid production during growth a mixture glucose xylose. Phylogenetically, the most closely related to Cystobasidium slooffiae, based on sequences ITS regions D1/D2 domain LSU rRNA gene. oleaginous, accumulating lipids levels > 20% dry cell weight. Moreover, kinetic analysis sugar-to-lipid conversion 1:1 glucose/xylose showed that consumed two sugars...
Parageobacillus thermoglucosidasius possesses biotechnological potential for fuel generation. Here, we report the draft genome sequence of P. strain TG4, which was first isolated from a marine sediment. The provides insight into plasmid diversity and carbon monoxide-dependent hydrogen production capacity thermoglucosidasius.
Three strains of novel oleaginous yeast species were isolated from soil samples collected in Shiga Prefecture, Japan. The sequences the internal transcribed spacer (ITS) region and D1/D2 large subunit (LSU) rRNA genes indicated that these are members genus Hannaella . results molecular phylogenetic analysis 38–3 8s1 closely related to oryzae They differed by 10 nucleotide substitutions one gap (1.77 %) LSU 17–18 10–11 gaps (5.45–5.85 ITS region. Strain 51–4 type strain most species,...
Draft genome sequences of the type strain (NBRC 1983) and a thermotolerant isolate (ATY839) xylose-fermenting yeast Scheffersomyces shehatae were determined. The sizes presumed open reading frames highly similar between strains NBRC 1983T ATY839.
The thermophilic Moorella sp. strains E308F and E306M were isolated from an acidic hot spring in Japan. Here, we report the draft genome sequences of (3.06 Mbp; G+C content, 54.0%) (2.99 54.4%), to advance genomic information available on genus Moorella.
The genus Thermanaeromonas comprises two species of thermophilic, strictly anaerobic, spore-forming bacteria. Here, we report the draft genome sequence sp. strain C210, which was first isolated in presence carbon monoxide. provides insight into monoxide-dependent metabolism for members Thermanaeromonas.
Abstract Prokaryotes, known as carbon monoxide (CO) oxidizers, use CO the or energy source with dehydrogenases (CODHs), which are divided into nickel-containing CODH (Ni-CODH) that sensitive to O 2 and molybdenum-containing (Mo-CODH) capable of aerobic functioning. The oxygen conditions for oxidizers oxidize may be limited because isolated characterized so far have either Ni- Mo-CODH. Here, we report a novel oxidizer oxidation both types based on genomic physiological characterization...
