• Amino Acids Participate Metabolic Interaction between Host and Pathogen: Study

  The research of AA-involved metabolic interaction between host and pathogen is beneficial to the treatment and prevention of epidemics, especially it will offer significant insight into pathogenic infections and reveal novel treatments to prevent and cure infections by modulating the abundance of AA or the metabolism of those AA.

• Urea Plus Nitrate Pretreatment of Straws Enhances Degradation and Reduces Methane Production

  Now,nitrate supplementation can make a difference. Therefore, ZHANG Xiumin and his team from ISA pre-treated rice and wheat straws by urea plus nitrate (urea+nitrate) together that can improve the degradation of straws and reduce the CH₄ production from ruminants.

• Scientists Identify Ruminal Methanogenic Pathway from Formate in Ruminants

  In order to explore the mechanistic insight in the formation of CH₄ and quantitatively evaluate the ruminal methane formation from formate, researchers from ISA investigated the carbon flow from formate to CH₄ and CO₂ using stable isotopic formate with 13^C in a batch culture system, where the inocula of ruminal fluid was collected from ruminally-fistulated goats to represent the ruminal environment.

  Intensive Multiple Nutrient Elements Input Results in Negative Priming Effect of Organic Matter in Paddy Soil

  The research team of the ISA used NH₄Cl, KH₂PO₄, and Ca₂SO₄·2H₂O as exogenous nutrient elements (N, P, K, Ca, and S) to figure out the features of organic carbon mineralization and its PE in flooded paddy soil under high and low nutrient concentration.

  Differential Soil Microbial Processes and Resource Limitation Found in Karst and Non-karst Forests

  Researchers in the ISA investigated two major microbial processes (i.e., the rates of decomposition and respiration) and the microbial resource limitation in a typical karst forest using eco-enzymatic stoichiometry as an indicator. A non-karst forest was also investigated as a comparison.

• The Mysteries Between Human Activities and Environmental Factors

  The researchers found that the NAPI values varied dynamically (318–924 kg P km^-2 yr^-1 in 1980 to 865–3601 kg P km^-2 yr^-1 in 2010) at the county scale in the Chinese subtropical region, in which the P fertilizer application was the largest source, accounting for 36.1–74.6%.
