Lactic acid bacteria are widely regarded as safe alternatives to antibiotics in livestock and poultry farming and have probiotic potential. () is a prominent component of pigeon crop microbiota; however, its function is unknown. In this study, a strain of 1003 from pigeon cecum was identified by combining whole genome sequencing and phenotypic analysis, and its safety and probiotic properties were studied.

The brain's substantial metabolic requirements, consuming a substantial fraction of the body's total energy despite its relatively small mass, necessitate sophisticated metabolic mechanisms for efficient energy distribution and utilization. The astrocyte-neuron lactate shuttle (ANLS) hypothesis has emerged as a fundamental framework explaining the metabolic cooperation between astrocytes and neurons, whereby astrocyte-derived lactate serves as a crucial energy substrate for neurons. This review synthesizes current understanding of brain energy metabolism, focusing on the dual roles of lactate as both an energy substrate and a signaling molecule.

Comonomer defects can induce semicrystalline polymers to form unique crystalline structures (., defect crystals), which can greatly influence the materials' physical properties. However, the formation mechanism and structural evolution of defect polymer crystals are not yet well understood.

Microcystin-LRs (MC-LR) produced by harmful cyanobacterial blooms (HCBs) pose significant hepatotoxic risks to both the environment and public health. Despite the identification and characterization of a limited number of MC-LR degrading bacteria, the challenge of safely removing MC-LRs from freshwater systems without disrupting aquatic ecosystems remains substantial. This study focused on the isolation of lactic acid bacteria from Bapshikhe, a traditional Korean fermented food, and investigated the mechanisms underlying the degradation of MC-LRs by these bacteria.
