Organic solid waste consists of 70 % biodegradables, such as cellulose, which is unable to be degraded quickly and efficiently in the cold region of China. Psychrotrophic cellulose-degrading bacteria play an important role in cellulose degradation at low temperatures In this study, a psychrotrophic cellulose-degrading FLX-7 strain with high carboxymethyl cellulase (CMCase) activity was isolated from the soil of a solid waste landfill under the environmental temperature of -10 °C. The FLX-7 strain was identified as Sphingobacterium sp. based on morphol. and physiol. and biochem. properties as well as 16S rRNA gene sequence anal. To improve the cold-active CMCase production of FLX-7, fermentation conditions were optimized using response surface methodol. based on a Box-Behnken design. The maximum CMCase activity (16.95 U/mL) was obtained at optimal fermentation conditions (inoculum size 2.1 %, temperature 10.4 °C, incubation time 73.5 h, and pH 7.2). The optimum pH and temperature for enzymic reaction of cold-active CMCase were 5.0 and 25 °C, resp. The cold-active CMCase was stable at a wide pH range of 5.0-9.0 and temperature range of 10-30 °C. The FLX-7 strain could be distributed via a psychrotrophic cellulose-degrading strain library and applied more broadly to organic solid waste composting in cold regions. In the experiment, the researchers used many compounds, for example, Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Application of 6381-59-5)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Application of 6381-59-5 It is utilized to break up emulsion in organic synthesis as well as a common precipitant in protein crystallography.
