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

The aim of experiment was to study the pyrolysis oil derived from sorted landfill plastic waste that had been buried for 15 years by the Nonthaburi Provincial Administrative Organization. The pyrolysis oil was produced using a Fixed-Bed Reactor at 450 °C for 1.5 hours with LPG as the feedstock, with the goal of using the pyrolysis oil as an alternative fuel. The experiment was conducted under four different conditions : (1) plastic waste buried in a landfill that has not been washed but has been reduced in size, (2) plastic waste buried in a landfill that has been washed and has been reduced in size, (3) plastic waste buried in a landfill that not has been washed and has not been reduced in size, (4) plastic waste buried in a landfill that has not been washed and has been reduced size, with activated carbon used as a catalyst. The experiment revealed that three products were produced : Oil, gas, and char in different quantity. The pyrolysis oil were compared in terms of quality based on pH, Heating value, Moisture content, Functional group, and Chemical Composition. The pyrolysis oil we obtained will be referenced according to the criteria from the Department of Energy Business. The analysis results of the pyrolysis can explain which conditions are suitable for replacing fuel oil in industrial It is therefore one of the approaches that helps manage plastic waste in landfills, reducing the quantity by converting it into usable 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.
