Summary: This paper proposes a new strategy to directly convert cellulose into sorbitol by regulating the activity of the catalyst. By using rice straw biochar as a carrier and Ru2P/C-SO3H as a catalyst, the yield of sorbitol was significantly improved.

Summary: The study found that crops sown on November 17 had the highest levels of bacteria, fungi, actinomycetes, soil microbial biomass carbon, dehydrogenase activity, and available nitrogen, phosphorus, potassium, and sulphur. When using nutrient sources, the combination of 75% recommended dose of fertilizers, 25% nitrogen from pressmud, Azotobacto, and phosphorus solubilizing bacteria showed the highest microbial population and nutrient content.

Summary: Climate change has significant effects on peatlands due to their large carbon stocks. Research shows that temperature and oxygen availability greatly impact soil respiration, and subsurface peat has lower CO2 production but higher temperature sensitivity.

Summary: We present a new method for the efficient conversion of biomass-derived carbohydrates into valuable 2-methylquinoxalines in the presence of aryl-1,2-diamines. This transformation can be achieved in water at room temperature and under ambient pressure, thanks to the synergistic effect of ultrasound and strong alkali. The proposed integrated chemo-enzymatic process enables the direct conversion of recalcitrant cellulose to 2-methylquinoxalines under near room-temperature conditions.

Summary: This study found that differences in microbial taxonomy and their temperature sensitivities play a key role in explaining variations in Q(10) of soil respiration, which is crucial for predicting feedbacks to climate change in ecosystems across the globe.

Summary: The economic production of cellulase enzymes is an important area of research, and this study focuses on improving cellulase production and activity using low-cost cellulosic substrates. The researchers used waste biomasses of water hyacinth to produce cellulases and investigated the impact of temperature and pH on enzyme production. They found that optimal conditions resulted in high cellulase production and activity, and the cellulase enzymes were able to effectively hydrolyze water hyacinth leaves to release glucose.

Summary: This study investigated the enhanced removal of p-chloronitrobenzene (p-CNB) in high-salinity wastewater using 1.2 V low-voltage stimulation and halotolerant microorganisms. The results showed a significant increase in p-CNB removal rate in the electrostimulating microorganism reactor compared to the control group. The stimulation also enhanced the salt-in strategy and extracellular polymeric substances secretion in the microorganisms. Metagenomic and metatranscriptomic analysis revealed the enrichment of specific microorganism populations with p-CNB removal ability under voltage stimulation.

Summary: This study explores the vertical and latitudinal patterns of soil microbial and enzymatic C-N-P contents and ratios in eight forest ecosystems in eastern China. The results show significant variations in C-N-P contents and stoichiometry with depth and latitude. Additionally, the correlations between C-N-P contents and latitude are stronger in surface soils compared to deep soils.

Summary: The carbon and nutrients in soil microbial biomass and their proportion in soil elements, known as soil microbial quotient, are key indicators of soil quality and respond quickly to changes in land-use patterns. Agriculture significantly decreases soil microbial biomass and quotient compared to grassland, with some improvement in microbial biomass after agriculture abandonment. It is crucial to maintain natural grasslands to protect and maintain soil microbial biomass and quotient in the meadow steppe of northeast China.

Summary: The salinisation of coastal ecosystems is ongoing and expected to continue due to climate change effects. Despite the importance of soil microbes for ecosystem functioning, their response to increased salinity in coastal environments is not well understood. Our research demonstrates a decline in the productivity of a key microbial group with rising coastal salinity, indicating early warning signs of coastal salinisation and potential impacts on soil and ecosystem function.

Summary: The study focused on the impact of rapid rewetting and slow rewetting of dry soil on soil respiration and nutrient cycling. Results showed that slow rewetting can increase the flush of respiration, but only if the second partial rewetting occurs 6 hours after the first.

Summary: Cumulative microbial respiration reflects microbial activities and their potential to support plant growth. In this study, we evaluated the cumulative microbial respiration of different salt tolerant rhizobacterial strains at different salinity levels and their ability to sustain plant growth under natural saline conditions using maize as a test crop. Our results showed that the strain 'SUA-14' performed the best, exhibiting the highest cumulative respiration compared to the un-inoculated control. Furthermore, the field trial results indicated significant improvements in various growth parameters and reductions in the negative effects of salinity stress due to the inoculation of strain 'SUA-14'.

Summary: The study demonstrated that the type of organic mulch used can affect the availability of nutrients and respiration rate in soil, with wheat straw enhancing nitrogen immobilization and reducing nitrogen leaching from faba bean mulch. The microbial biomass nitrogen was significantly higher in soil mixed with wheat and mulched.
