The high fibrolytic activity and large biomass of strictly-anaerobic bacteria that inhabit the rumen makes them primarily responsible for the degradation of the forage consumed by ruminants. Llamas feed mainly on low quality fibrous roughages that are digested by an active and diverse microflora. The products of this fermentation are volatile fatty acids and microbial biomass, which will be use...

BACKGROUND Sustainable and economically viable manufacturing of bioethanol from lignocellulose raw material is dependent on the availability of a robust ethanol producing microorganism, able to ferment all sugars present in the feedstock, including the pentose sugars L-arabinose and D-xylose. Saccharomyces cerevisiae is a robust ethanol producer, but needs to be engineered to achieve pentose su...

Some strains of Staphylococcus epidermidis and Micrococcus sp. produce nucleases. However, thermal stability was shown to be unique to the nucleases of S. aureus. In addition, two micromethods for susceptibility testing to lysostaphin were more precise and convenient than anaerobic glucose fermentation in distinguishing between the genera Staphylococcus and Micrococcus.

Eubacterium limosum ATCC 8486 is an anaerobic chemolithoautotrophic acetogenic bacterium that converts and transforms syngas and isoflavonoids to butanol and phytoestrogens, respectively. Here, we report the draft genome sequence of the E. limosum ATCC 8486 (4.37 Mb) strain and its annotation information, including syngas fermentation and denitrification metabolic pathways.

Clostridium drakei SL1(T) is a strictly anaerobic, H2-utilizing, and acid-tolerant acetogen isolated from an acidic sediment that is a potential platform for commodity chemical production from syngas fermentation. The draft genome sequence of this strain will enable determination of the acid resistance and autotrophic pathway of the acetogen.

The goal of this study was to develop a fungal process for ethanol production from corn fiber. Laboratory-scale solid-substrate fermentation was performed using the white-rot fungus Phanerochaete chrysosporium in 1 L polypropylene bottles as reactors via incubation at 37 degrees C for up to 3 days. Extracellular enzymes produced in situ by P. chrysosporium degraded lignin and enhanced saccharif...

12 Microbial electrosynthesis (MES) and anaerobic fermentation (AF) are two biological processes 13 capable of reducing CO2, CO and water into acetic acid, an essential industrial reagent. In this 14 study, we evaluated investment and production costs of acetic acid via MES and AF, and compared 15 them to industrial chemical processes: methanol carbonylation and ethane direct oxidation. 16

The ruminant animal is dependent upon anaerobic microorganisms for the digestion of plant materials in the rumen. The resultant microbial cells and fermentation acids are primary nutrients for the animal. Polysaccharides, such as hemicelluloses, are only partially degraded because of the chemical complexities of plant materials and biochemical processes involved in degradation.

Tirandalydigin a structurally unique hybrid of the tirandamycin-streptolydigin families of tetramic acid antibiotics has been isolated from the fermentation beers of Streptomyces sp. AB-1006A-9. The structure of this anti-anaerobic antibiotic has been characterized based upon NMR, UV and mass spectrometric data.

Two new ethanologenic strains (FBR4 and FBR5) of Escherichia coli were constructed and used to ferment corn fiber hydrolysate. The strains carry the plasmid pLOI297, which contains the genes from Zymomonas mobilis necessary for efficiently converting pyruvate into ethanol. Both strains selectively maintained the plasmid when grown anaerobically. Each culture was serially transferred 10 times in...
