Summary: Citrus, a famous fruit worldwide, is prone to green mold caused by Penicillium digitatum, resulting in significant economic losses. e-Poly-l-lysine (e-PL), a novel preservative, has strong inhibitory effects on fungi and can induce disease resistance in fruit. However, the mechanism of e-PL-induced resistance in citrus has been rarely reported. In this study, it was found that e-PL effectively inhibited the development of green mold in citrus without direct contact with P. digitatum, indicating the activation of disease resistance. Transcriptome analysis revealed that e-PL activated amino acid metabolism and phenylpropanoid biosynthesis, leading to the accumulation of phenolic compounds. These findings enhance our understanding of e-PL-induced disease resistance and provide a theoretical basis for its application in postharvest citrus preservation.

Summary: The study found that different charged amino acids (lysine, aspartic acid, and tyrosine) have inhibitory effects on the long-term retrogradation of normal corn starch gel, with lysine showing the most significant effect and tyrosine the least. These amino acids can reduce the retrogradation enthalpy, hardness, and R1047/1022 value of the gel, as well as inhibit the recrystallization process.

Summary: In response to a request from the European Commission, the FEEDAP was asked to assess the safety of l-lysine monohydrochloride and l-lysine sulfate produced by Corynebacterium glutamicum CGMCC 17927 as nutritional additives in animal feed and water. The Panel concluded that there were no safety concerns regarding the production strain and that the additives were safe for the target species. However, administering amino acids simultaneously in feed and water may pose risks of nutritional imbalances and hygienic concerns. The use of both forms of l-lysine produced by fermentation using C. glutamicum CGMCC 17927 was considered safe for consumers and the environment. Limited data prevented the Panel from concluding on potential skin and eye irritation or dermal sensitization. l-Lysine HCl and l-lysine sulfate were deemed effective sources of the essential amino acid for non-ruminant animal species, but protection against rumen degradation would be necessary for efficacy in ruminants.

Summary: In this study, two types of amphiphilic poly(glutamic acid) nanoparticles as nanocarrier adjuvants were fabricated to effectively induce cellular immune response. The alpha-PGA-F NPs, with their pH-responsive alpha-helical secondary structure, demonstrated enhanced membrane fusion and antigen lysosomal escape compared to the gamma-PGA-F NPs. This led to higher secretion of inflammatory cytokines and increased expression of major biological histocompatibility complex class I and CD80, making the alpha-PGA-F NPs a potent candidate for vaccine applications.

Summary: The suitable dietary L-lysine concentration for coho salmon alevins was determined through a dose-response feeding trial. The study found that the specific growth rate, protein efficiency ratio, and body protein deposition increased significantly with increasing dietary lysine concentration up to 3.80%. However, further increases in lysine level led to a decrease in these growth parameters. The highest contents of lysine, arginine, and total essential amino acids were observed in the group with 4.27% dietary lysine concentration.
