Siamese fighting fish (Betta splendens) is an ornamental fish that is the first exported economically valuable fish in the country, but there is a limitation to increase the production of betta fish due to climate variability and the shortage of Thai workers. This research aims to develop 2 systems: a betta fish fry nursery system and a market-sized betta fish rearing system by using automated technology to precisely control the water quality in the system and reduce labor costs. Using precise automation consists of two systems: a minimal-waste system, which repurposes some of the waste generated from farming, and a zero-waste system, which treats and recycles all wastewater from farming. These systems aim to address issues related to water quality, animal welfare, and labor requirements in Betta fish farming. Experimental results show that these systems improve Betta fish survival rates by 10-15% compared to traditional methods. When considering net returns, the zero- waste system provides the highest profitability.
ในการเพาะเลี้ยงปลากัดประกอบด้วย ระบบอนุบาลลูกปลากัด เป็นการเลี้ยงลูกปลากัดในบ่อปูนซีเมนต์ขนาดเส้นผ่านศูนย์กลาง 60-80 เซนติเมตร มีการเพิ่มระดับน้ำแทนการเปลี่ยนถ่ายน้ำสัปดาห์ละ 5-10 เซนติเมตรจากระดับน้ำเดิม และการเลี้ยงปลาขนาดตลาด เป็นการเลี้ยงปลากัดในขวดแบนเรียงต่อกันจำนวนมากบนพื้นคอนกรีต มีการให้อาหารหรือเปลี่ยนถ่ายน้ำโดยใช้แรงงานคน 1 คนต่อการเลี้ยงปลากัด 10,000 – 40,000 ตัว ดังนั้นระบบอนุบาลและการเลี้ยงปลากัดขนาดตลาดแบบพัฒนาใหม่โดยใช้เทคโนโลยีในการควบคุมคุณภาพน้ำ การให้อาหารและการเปลี่ยนถ่ายน้ำด้วยระบบอัตโนมัติ จะช่วยแก้ปัญหาอัตราการตายของปลา การใช้แรงงาน และยังสามารถเพิ่มอัตราการรอดของลูกปลากัดได้อีกด้วย

Bacteriocins are microbial peptides that demonstrate potency against pathogens. This study evaluated the inhibitory effects on pathogens and characterized the bacteriogenomic profile of strain TKP1-5, isolated from the feces of Anas platyrhynchos domesticus. Strain TKP1-5 was characterized using phenotypic traits, 16S rRNA sequencing, and Whole-Genome Sequencing (WGS). It exhibited growth in the presence of 2-6% NaCl, temperatures of 25-45°C, and pH levels ranging from 3 to 9. Based on ANIb, ANIm, and dDDH values, strain TKP1-5 was identified as Lactococcus lactis. Whole genome analysis revealed that strain TKP1-5 harbors the Nisin Z peptide gene cluster with a bit-score of 114.775. The antimicrobial spectrum of bacteriocin TKP1-5 showed inhibitory effects against pathogenic bacteria including Pediococcus pentosaceus JCM5885, Listeria monocytogenes ATCC 19115, Enterococcus faecalis JCM 5803T, Salmonella Typhimurium ATCC 13311ᵀ, Aeromonas hydrophila B1 AhB1, Streptococcus agalactiae 1611 and Streptococcus cowan I. Genomic analysis confirmed L. lactis TKP1-5 as a non-human pathogen without antibiotic resistance genes or plasmids. Furthermore, L. lactis TKP1-5 contains potential genes associated with various probiotic properties and health benefits. This suggests that L. lactis TKP1-5, with its antibacterial activity and probiotic potential, could be a promising candidate for further research and application in the food industry.

Diabetes is a significant global health issue, particularly due to complications related to diabetic wounds. Studies indicate that approximately 15-25% of diabetic patients develop foot ulcers, with more than 50% of severe cases leading to amputation. This results in a substantial decline in the quality of life for patients. Current treatments for diabetic wounds face challenges such as antibiotic-resistant bacterial infections and delayed wound healing, highlighting the need for innovative solutions to accelerate the healing process and reduce the risk of limb loss. Cotylelobium lanceolatum Craib, a medicinal plant long utilized in traditional Thai medicine, is known for its anti-inflammatory and wound-healing properties. This study focuses on developing an extract from Cotylelobium lanceolatum Craib in the form of nano silver (Nano Silver) to enhance the effectiveness of diabetic wound treatment. Nano silver technology enables deeper penetration into the skin, provides potent antibacterial activity, and promotes wound healing by reducing inflammation and stimulating tissue regeneration. The development of nano silver derived from Cotylelobium lanceolatum Craib extract is expected to help reduce chronic wounds in diabetic patients, lower the risk of infection, and decrease the incidence of limb amputation and mortality associated with diabetic wound complications. This research represents a significant step toward creating a safer and more effective treatment alternative for diabetic wound care.

An automated hydroponic system for household use has been developed to cater to individuals with limited space who wish to conveniently and easily grow their own salad greens at home. This system is designed to automatically control nutrient delivery by setting appropriate electrical conductivity (EC) and pH levels tailored to the specific salad greens being grown. It includes artificial lighting to enable cultivation in confined spaces with insufficient sunlight and is more cost-effective than similar systems available on the market. System testing revealed that the automated control of EC and pH values performed effectively, achieving the preset levels within 30 minutes and maintaining them consistently throughout operation. In an experiment growing green oak lettuce using a simulated balcony setup, the plants demonstrated a higher growth rate compared to conventional methods, particularly when artificial lighting was used.
