The purpose of this invention is to develop a forest fire prevention agent that has the ability to prevent long-term forest fires, not only to suppress forest fires or prevent forest fires from spreading widely, but to prevent them from starting to catch fire from the beginning. It can prevent forest fires comprehensively and can be prevented for a long time during the peak forest fire period or the dry season, which is about 3-4 months. There are no residues or minimal residues without causing harm to the surrounding environment under the specified standards. Emphasis is placed on the use of raw materials, equipment, and chemicals that can be easily found in Thailand. This includes using the value of production costs as low as possible. This makes it suitable for use in large quantities for spraying and protecting forest areas in forest areas that are prone to fire. Estimated average for pollution caused by forest fires include particulate matter (PM), including PM2.5, PM10, carbon monoxide (CO), carbon dioxide, carbon dioxide, and carbon dioxide, Nitrogendioxide, VOC etc.
ป่าไม้เป็นทรัพยากรธรรมชาติที่มีคุณค่าต่อมนุษย์มากมาย ป่าไม้เป็นแหล่งปัจจัยพื้นฐานสี่ประการที่ทำให้มนุษย์สามารถดำรงชีวิตอยู่ได้ นอกจากนี้ป่าไม้ยังเป็นที่อยู่ของสิ่งมีชีวิตต่างๆรวมถึงสัตว์ป่าและพืชพรรณนานาชนิด ปัญหาไฟป่าเป็นอีกปัจจัยที่ส่งผลให้ทรัพยากรป่าไม้เสื่อมโทรมลงอย่างมาก ส่งผลให้ป่าไม้ไม่สามารถฟื้นตัวได้ทันตามวัฏจักรธรรมชาติ ปัจจุบันประเทศไทยได้สูญเสียพื้นที่ป่าไปเป็นจำนวนมากกว่า 1000000 ไร่ในสิบปีหลังสุด และผลกระทบจากไฟป่าทำให้เกิดปัญหาหมอกควันกระจายท้่วไปในบริเวณภาคเหนือ ภาคกลาง และตะวันออกเฉียงเหนือของประเทศ ทำให้ประชาชนจำนวนมากประสบปัญหาโรคระบบทางเดินหายใจ นวัตกรรมนี้จึงถูกสร้างขึ้นเพื่อต้องการลดปัญหาไฟป่าและปกป้องคลุมครองพื้นที่ป่าของประเทศ

Stirling engine is the external heated engine that heat is sup-plied externally to the heater part of the engine. Thus, Stirling cycle engine can be employed with various sources of renewable energy such as biomass, biofuel, solar energy, geothermal energy, recovery heat, and waste. The integration of gasifier, burner, and heat engine as a power system offers more fuel choices of each local area with potential resources resulting independent from shortage and cost fluctuation of fossil fuel. This research aims to investigate the integration of the Stirling engine with a wood pellet gasifier for electric power generation. Biomass can be controlled to have continuously combustion with ultra-low toxic emission. Stirling engine, therefore, is a promising alternative in small-scale-electricity production. Even though many biomass-powered Stirling engines were successfully constructed and marketed but these engines and the use of biomass resources as fuel for power generation are quite new concepts in some developing countries. Especially, the capital cost of this engine is high and unaffordable for installation compared to other power systems. Therefore, this research aims to the study attractive and feasibility of the compact Stirling engine with green energy.

Listeriosis is a severe foodborne illness characterized by a fatality rate exceeding 30%, attributed to the pathogen Listeria monocytogenes. This study evaluated 160 lactic acid bacteria (LAB) isolated from Thai pickled crabs for their potential as agents against L. monocytogenes and for their probiotic properties and probiogenomic characteristics. Among these strains, strain DRC3-2 exhibited activity through the synthesis of bacteriocin DRC3-2, which significantly inhibited L. monocytogenes ATCC 19115 in spot-on-lawn assays. Phenotypic and whole-genome analyses revealed that strain DRC3-2 thrived in environments with 2-6% NaCl, pH values ranging from 3 to 9, and temperatures between 25 and 45°C. Based on average nucleotide identity (ANI) and digital DNA‒DNA hybridization (dDDH) values, strain DRC3-2 was taxonomically classified as Lactococcus lactis subsp. hordinae. The production of bacteriocin DRC3-2 peaked during the late stationary phase, following its synthesis in the early exponential growth phase. BAGEL4 analysis identified the putative novel bacteriocin DRC3-2 as lactococcin A and B, with respective bit-scores of 40.05 and 36.58. In silico safety assessments confirmed the nonpathogenic nature of strain DRC3-2 in humans, highlighting its absence of antibiotic resistance genes. Finally, this investigation underscores the novel bacteriocin DRC3-2 for application in the prevention and treatment of L. monocytogenes infections.
