A screening for dye-decolorizing alkali-thermophilic microorganisms resulted in a Bacillus sp. strain isolated out of the wastewater drain of a textile finishing company. An NADH-dependent azoreductase of this strain, Bacillus sp. strain SF, was found to be responsible for the decolorization of azo dyes. This enzyme was purified by a combination of ammonium sulfate precipitation and anion-excha...
Bacillus accelerates lignocellulose degradation, promotes the stabilization and resource utilization of compost by secreting enzymes, plays an important role in formation quality control. This study evaluated enzyme activity, lignocellulosic bacterial succession composting inoculated with different microbial agents. They were identified as B. licheniformis, subtilis, thermoamylovorans, thermoru...
BACKGROUND The demand for lactic acid has been increasing considerably because of its use as a monomer for the synthesis of polylactic acid (PLA), which is a promising and environment-friendly alternative to plastics derived from petrochemicals. Optically pure L-lactic acid is essential for polymerization of PLA. The high fermentation cost of L-lactic acid is another limitation for PLA polymers...
Background: Pectinases are pectin degrading class of enzymes including polygalacturonase (PG), polymethyl galacturonase (PMG), pectate lyase (PEL), and pectin esterase (PE) that are commonly used in processes involving the degradation of plant materials, such as speeding up the extraction of fruit juices. Objectives: A highly methylated pectin degrading bacterium from soil covered with fruit wa...
Studies on a Thermophilic Bacillus: Its Isolation, Properties, and Temperature Coefficient of Growth
This study aims to create a quantitative polymerase chain reaction (q-PCR) methodology for monitoring the hydrogen-producing mixed cultures enriched from elephant dung using alpha-cellulose as carbon source through five generations of repetitive sub-culture. The thermophilic fifth cultivation cycle gave highest hydrogen yield 170.3 mL H2/g cellulose and were used generate sawdust. Clostridium s...
