Chemical structures and biological activities of rhamnolipids produced by Pseudomonas aeruginosa B189 isolated from milk factory waste

Thanomsub B.; Pumeechockchai W.; Limtrakul A.; Arunrattiyakorn P.; Petchleelaha W.; Nitoda T.; Kanzaki H. (2006)

The aim of this work was to study chemical structures and biological activities of rhamnolipids produced by Pseudomonas aeruginosa B189 isolated from milk factory waste. The culture produced two biosurfactants, a and b, ...
Chitosan and chitooligosaccharides from shrimp shell waste: characterization, antimicrobial and shelf life extension in bread

Rakkhumkaew N.; Pengsuk C. (2018)

Chitosan and chitooligosaccharides were extracted from white-leg shrimp shells by chemical treatment. Low molecular weight (13 kDa) and a high degree of deacetylation (54.83%) in chitooligosaccharides led to high water ...
Detection of the shrimp pathogenic bacteria, Vibrio harveyi, by a quartz crystal microbalance-specific antibody based sensor

Buchatip S.; Ananthanawat C.; Sithigorngul P.; Sangvanich P.; Rengpipat S.; Hoven V.P. (2010)

An immunosensor based on a quartz crystal microbalance (QCM) was developed for detection of Vibrio harveyi (V. harveyi), a pathogenic bacteria causing morbidity and even a high level of fatality in commercial shrimp cultures, ...
Development of a duplex lateral flow dipstick test for the detection and differentiation of Listeria spp. and Listeria monocytogenes in meat products based on loop-mediated isothermal amplification

Ledlod S.; Bunroddith K.; Areekit S.; Santiwatanakul S.; Chansiri K. (2020)

Listeria spp. are a group of gram-positive bacteria consisting of 20 species. Among them, Listeria monocytogenes is one of the major species that infects humans since it contaminates raw fruits, vegetables, and many others ...
Development of a Rapid Screening Test for Listeria monocytogenes in Raw Chicken Meat Using Loop-Mediated Isothermal Amplification (LAMP) and Lateral Flow Dipstick (LFD)

Wachiralurpan S.; Sriyapai T.; Areekit S.; Kaewphinit T.; Sriyapai P.; Santiwatanakul S.; Chansiri K. (2017)

A loop-mediated isothermal amplification and lateral flow dipstick (LAMP-LFD) protocol was established for the rapid detection of the foodborne pathogen Listeria monocytogenes based on detection of the phosphatidylcholin ...
Diversity of cultivable hydrogen-producing bacteria isolated from agricultural soils, waste water sludge and cow dung

Kanso S.; Dasri K.; Tingthong S.; Watanapokasin R.Y. (2011)

This project aimed to study the diversity of cultivable hydrogen-producing bacteria, isolated from agricultural soils, waste water sludge and cow dung by analyzing 16S rRNA gene. Isolation performed anaerobically on nutrient ...
Humanized-monoclonal antibody against heterologous leptospira infection

Maneewatch S.; Sakolvaree Y.; Tapchaisri P.; Saengjaruk P.; Songserm T.; Wongratanachewin S.; Tongtawe P.; Srimanote P.; Chaisri U.; Chaicumpa W. (2009)

Patients with leptospirosis are commonly treated with antibiotics. Jarisch-Herxheimer reaction caused by toxic bacterial substances massively released as a result of the antibiotic mediated-bacterial lysis occurs in some ...
Hydrogen production and anaerobic decolorization of wastewater containing Reactive Blue 4 by a bacterial consortium of Salmonella subterranea and Paenibacillus polymyxa

Watanapokasin R.Y.; Boonyakamol A.; Sukseree S.; Krajarng A.; Sophonnithiprasert T.; Kanso S.; Imai T. (2009)

Anaerobic biodegradability of wastewater (3,000 mg CODcr/l) containing 300 mg/l Reactive Blue 4, with different co-substrates, glucose, butyrate and propionate by a bacterial consortium of Salmonella subterranea and ...
N-glycosylation deficiency enhanced heterologous production of a Bacillus licheniformis thermostable α-amylase in Saccharomyces cerevisiae

Hoshida H.; Fujita T.; Cha-Aim K.; Akada R. (2013)

Expression of foreign enzymes in yeast is a traditional genetic engineering approach; however, useful secretory enzymes are not produced in every case. The hyperthermostable α-amylase encoded by the AmyL gene of Bacillus ...
Production, purification and characterization of an ionic liquid tolerant cellulase from Bacillus sp. Isolated from rice paddy field soil

Sriariyanun M.; Tantayotai P.; Yasurin P.; Pornwongthong P.; Cheenkachorn K. (2016)

Background: Lignocellulosic biomass is a renewable, abundant, and inexpensive resource for biorefining process to produce biofuel and valuable chemicals. To make the process become feasible, it requires the use of both ...
Purification, characterization, and overexpression of an endo-1,4-β-mannanase from thermotolerant Bacillus sp. SWU60

Seesom W.; Thongket P.; Yamamoto T.; Takenaka S.; Sakamoto T.; Sukhumsirichart W. (2017)

Endo-β-1,4-mannanases are important catalytic agents in several industries. The enzymes randomly cleave the β-1,4-linkage in the mannan backbone and release short β-1,4-mannooligosaccharides and mannose. In the present ...
Purification, characterization, and overexpression of thermophilic pectate lyase of bacillus sp. rn1 isolated from a hot spring in Thailand

Sukhumsiirchart W.; Kawanishi S.; Deesukon W.; Chansiri K.; Kawasaki H.; Sakamoto T. (2009)

A thermophilic pectate lyase, Pel SWU, was isolated from a culture filtrate of Bacillus sp. RN1 isolated from a hot spring in Ranong Province, Thailand. The enzyme was purified to homogeneity using cation-exchange and ...
