Probiotics are increasingly used as functional food ingredients. The objectives of this study were to isolate and characterise probiotic bacteria from dairy fermented foods use a selected strain for the production chèvre cheese. Tolerance acid (pH 2.0) bile salt (0.4% (w/v)) first investigated, then other properties determined. Out 241 isolates, 35 showed high tolerance salt, 6 chosen further characterisation. They Lactobacillus plantarum L. fermentum, possessed antibacterial activities...
Kombucha bacterial cellulose (KBC), a by-product of kombucha fermentation, can be used as biomaterial for microbial immobilization. In this study, we investigated the properties KBC produced from green tea fermentation on days 7, 14, and 30 its potential protective carrier Lactobacillus plantarum, representative beneficial bacteria. The highest yield (6.5%) was obtained day 30. Scanning electron microscopy showed development changes in fibrous structure over time. They had crystallinity...
The Bacillus cereus group frequently contaminates milk and dairy products. Some members of this can produce the heat-stable pre-formed toxin cereulide, which causes emetic foodborne intoxication. This study characterised B. isolates from raw cow’s in biochemical, genetic, toxigenic aspects. Of 158 derived 99 samples, 7 (4.43%) harboured cereulide synthetase A (cesA), encodes a associated with phenotype. Heat-treated culture filtrates cesA-positive demonstrated cytotoxicity to HepG2 Caco-2...
Isoprene, a biogenic volatile compound emitted largely by plants, can form greenhouse gases when it reacts with atmospheric radicals. A significant amount of isoprene is absorbed into soil and be degraded microorganisms, but our understanding the microbial biodegradation in tropical ecosystems remains limited. This study investigated degradation microbes indigenous to evergreen forest, focusing on those associated coffee tea plants grown as integrated crops their genome characteristics...
ABSTRACT Bacillus cereus , bacteria that commonly occur in foods, can potentially cause foodborne illness. Two important factors contribute to the illness are number of B. food and ability organism produce enterotoxins. This study investigated cells dairy cereal products Thailand, using plate count method presence diarrheal‐enterotoxin genes isolates through polymerase chain reaction (PCR). The encoding hemolysin BL (hblA, hblC, hblD), nonhemolytic enterotoxin (nheA, nheB, nheC), cytotoxin K...
Rice is one of the most important food crops in many countries, with nutritional value and health benefits. In this study, ethanolic aqueous extracts red jasmine rice from Chiang Mai, Thailand were examined for their anthocyanins phenolic contents. The antioxidant antiviral activity against herpes simplex virus type 1 (HSV-1) 2 (HSV-2), as well anticancer activity, investigated. total content 708.03 ± 11.56 mg Cy-3-glc equivalent/g extract, determined was higher than extract. However,...
Northern Thailand, the main part of Lanna region, is home to a diverse range ethnic groups, each with their own food and cultural heritage. The bacterial compositions in fermented soybean (FSB) products indigenous three ethnolinguistic including Karen, Lawa, Shan, were investigated this study. Bacterial DNA was extracted from FSB samples subjected 16S rRNA gene sequencing using Illumina platform. Metagenomic data showed that predominant bacteria all FSBs members genus Bacillus (49.5-86.8%),...
Many indigenous fermented foods of Northern Thailand and neighbouring regions have traditionally been known for their health benefits. In this study, we explored the communities bacteria in selected which are commonly consumed among ethnic groups around Thailand, information on microbial compositions or functional properties is still limited. The food included Thua Nao (alkaline soybean product), Nham (fermented pork sausage/loaf), Nam phak Chinese cabbage) Miang leaves from Tea trees)....
In this study, we aim to investigate the efficiency of crude oil bioremediation through composting and culture-assisted composting. First, forty-eight bacteria were isolated from a oil-contaminated soil, isolate with highest degradation activity, identified as Pseudomonas aeruginosa, was selected. The then investigated compared between soil (S), contaminated composted fruit-based waste (SW), same addition selected bacterium (SWB). Both compost-based methods showed high efficiencies (78.1%...
Mastitis caused by bacterial infection has negative impacts on milk quality and animal health, ultimately causes economic losses to the dairy industry worldwide. Gram-negative bacteria their component lipopolysaccharide (LPS) can trigger inflammatory response of endothelial cells (ECs) subsequently promote EC dysfunction or injury, which is a critical pathogenesis mastitis-causing sepsis shock. To control minimise LPS effects ECs, we thus aimed identify potential herb extracts that comprised...
Hydrogen sulfide (H2S) is a toxic and corrosive component that commonly occurs in biogas. In this study, H2S removal from swine-waste biogas using sulfur-oxidizing Paracoccus versutus CM1 immobilized porous glass (PG) polyurethane foam (PUF) biofilters was investigated. Bacterial compositions the were also determined polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). The first tested on laboratory scale under three space velocities (SV): 20, 30, 40 h−1. Within 24...
Isoprene is a climate-active biogenic volatile organic compound (BVOC), emitted into the atmosphere in abundance, mainly from terrestrial plants. Soil an important sink for isoprene due to its consumption by microbes. In this study, we report ability of soil bacterium degrade isoprene. Strain 13f was isolated beneath wild Himalayan cherry trees tropical restored forest. Based on phylogenomic analysis and Average Nucleotide Identity score >95%, it most probably belongs species Alcaligenes...
Microbial Enhanced Oil Recovery (MEOR) is a promising strategy to improve recovery of residual oil in reservoirs, which can be performed by promoting specific indigenous microorganisms. In this study, we preliminary evaluation the possibility conducting MEOR at Mae Soon reservoir, an onshore reservoir Northern Thailand. The reservoir's physicochemical characteristics, including characteristics wells, oil-bearing sandstone cores, and produced water, were determined. microbiological wells also...
This study describes an emetic food-borne intoxication associated with a Bacillus cereus group species and the characterization of bacterial isolates from incident in aspects molecular tying, genetic factors, cytotoxicity, pathogenic mechanisms relating to illness. Through polyphasic identification approach, all seven obtained food clinical samples were identified as thuringiensis. According multilocus sequence typing (MLST) analysis, intraspecific diversity was found within B. thuringiensis...
The Lanna region, the main part of northern Thailand, is a place ethnic diversity. In this study, we investigated phak-gard-dong (PGD), or pickled mustard green (Brassica juncea L. Czern.), for its beneficial bacteria content and to analyse variations in bacterial compositions among PGD three different ethnolinguistic groups, Karen, Lawa, Shan. DNA was extracted from brine, 16S rRNA gene Illumina sequencing performed. Metagenomic data were analysed results demonstrated that dominant species...

Isoprene, a volatile hydrocarbon emitted largely by plants, plays an important role in regulating the climate diverse ways, such as reacting with free radicals atmosphere to produce greenhouse gases and pollutants. Isoprene is both deposited formed soil, where it can be consumed some soil microbes, although much remains understood about isoprene consumption tropical soils. In this study, isoprene-degrading bacteria from soils associated plants were investigated cultivation...
