The species Enterococcus lactis is closely related to E. faecium and is known for its beneficial and probiotic effects. In this study, strain RRS4 was isolated from Raphanus sativus Linn. and identified based on both phenotypic and genotypic characteristics. Strain RRS4 exhibited cell viability in environments with 2-8% NaCl, pH ranging from 4 to 9, and temperatures between 4°C and 45°C. Through comprehensive genomic analysis, strain RRS4 was confirmed to be E. lactis. E. lactis RRS4 demonstrated inhibitory effects against Vancomycin-resistant E. faecalis JCM 5803. Safety assessments via in silico methods, including KEGG annotation, indicated the absence of virulent and undesirable genes in E. lactis RRS4. VirulenceFinder analysis aligned virulence-related genes with those from three strains of E. lactis and four strains of E. faecium. While antibiotic resistance genes were found to be conserved, they did not correlate with key pathogenicity traits. Furthermore, safety evaluations highlighted that E. lactis RRS4 is generally safe, despite the presence of genes associated with antibiotic resistance. Lastly, we propose guidelines for assessing the safety of microbial strains using whole-genome analysis. These findings represent advancements in probiotic research.
ปัจจุบันมีงานวิจัยเกี่ยวกับโพรไบโอติกส์เพิ่มมากขึ้น เนื่องจากโพรไบโอติกส์มีประโยชน์ต่อสุขภาพมนุษย์โดยเฉพาะระบบทางเดินอาหาร เช่น ช่วยการปรับสมดุลลำไส้ กระตุ้นการทำงานของ ระบบภูมิคุ้มกัน ส่งเสริมกระบวนการย่อยอาหาร ลดระดับคอเลสเตอรอล ถึงแม้โพรไบโอติกส์จะมีประโยชน์มากแต่ก็ควรบริโภคในปริมาณที่เหมาะสม หากได้รับมากเกินไปอาจส่งผลเสียต่อร่างกายได้ โดยโพรไบโอติกส์สามารถพบได้ทั้งในแบคทีเรียและยีสต์ที่มีชีวิตหลายชนิด แต่ชนิดที่พบมากที่สุดและถูกใช้ในผลิตภัณฑ์อาหารเสริมมักจะอยู่ในกลุ่มของแบคทีเรียกรดแลคติก

Currently, Thailand is facing the issue of an aging agricultural workforce and a shortage of labor. The hiring process for agricultural workers is primarily based on word-of-mouth within a limited, narrow area. This may have indirect negative effects in various aspects, such as the lack of basic selection criteria (experience, skills), budget control, and hiring processes. As a result, the idea of creating a job platform specifically for farmers was conceived.Currently, Thailand is facing the issue of an aging agricultural workforce and a shortage of labor.

Agricultural products and by-products are important raw materials in various industries including cosmetics and pharmaceuticals. Agro-based fibers have the composition, properties and structure that make them suitable for uses as composite-cosmetic industry. Upon microwave digestion, cellulose have been successfully synthesized into nanocrystalline cellulose (NCC) with lengths from 50-1000 nm, widths between 5-70 nm. Nanocrystalline cellulose was grafted with cosmetic active ingredients such as glycerin), sodium hyaluronate), glycolic acid, and nicotinamide. The beauty active ingredients attached nanocelluloses can penetrate through the skin to enhance beauty and youth.
