Use of oleaginous microorganisms as "micro-factories" for accumulation single cell oils biofuel production has increased significantly to mitigate growing energy demands, resulting in efforts upgrade industrial waste, such second-generation lignocellulosic residues, into potential feedstocks. Dilute-acid pretreatment (DAP) is commonly used alter the physicochemical properties materials and typically coupled with simultaneous saccharification fermentation (SSF) conversion sugars ethanol. The...
Acidovorax sp. strain JS42 uses 2-nitrotoluene as a sole source of carbon and energy. The first enzyme the degradation pathway, 2,3-dioxygenase, adds both atoms molecular oxygen to 2-nitrotoluene, forming nitrite 3-methylcatechol. All three mononitrotoluene isomers serve substrates for dioxygenase, but is unable grow on 3- or 4-nitrotoluene. Using long- short-term selections, we obtained spontaneous mutants that grew 3-nitrotoluene. strains by selection had mutations in gene encoding α...
Photosynthetic algae represent a large, diverse bioresource potential. Yellow-green of the genus Tribonema are candidates for production biofuels and other bioproducts. We report on filamentous isolate from an outdoor raceway polyculture growing municipal reclaimed wastewater which we classified as T. minus. Over one year cultivation in 3.5 m2 ponds fed by wastewater, minus cultures were more productive than native algal polycultures, with annual average productivities 15.9 ± 0.3 13.4 0.4...
Nitramines are key constituents of most the explosives currently in use and consequently contaminate soil groundwater at many military facilities around world. Toxicity from nitramine contamination poses a health risk to plants animals. Thus, understanding how nitramines biodegraded is critical environmental remediation. The biodegradation synthetic compounds such as hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) has been studied for decades, but little known about catabolism naturally...

Here, we report the annotated genome sequence for a heterokont alga from class Xanthophyceae . This high-biomass-producing strain, Tribonema minus UTEX B 3156, was isolated wastewater treatment plant in California. It is stable outdoor raceway ponds and promising industrial feedstock biofuels bioproducts.
ABSTRACT Streptomyces vitaminophilus produces pyrrolomycins, which are halogenated polyketide antibiotics. Some of the pyrrolomycins contain a rare nitro group located on pyrrole ring. The 6.5-Mbp genome encodes 5,941 predicted protein-coding sequences in 39 contigs with 71.9% G+C content.
Genes responsible for the anaerobic catabolism of benzoate in thermophilic archaeon Ferroglobus placidus were expressed lignocellulose-degrading bacterium Caldicellulosiruptor bescii, as a first step to engineering this degrade lignin metabolite. The benzoyl-CoA ligase gene was individually, and combination with reductase putative transporter. This effort also assessed heterologous expression from synthetically designed operon whereby each coding sequence proceeded by unique C. bescii...
