A novel monoclonal antibody (MAb) against oxytetracycline (OTC) was generated and characterized. The MAb was used in the development of an enzyme-linked immunosorbant assay (ELISA)-based detection system. An OTC-bovine serum albumin (BSA) conjugate was prepared and used in the immunization of mice. A conventional somatic cell fusion technique was used to(More)
Clostridium acetobutylicum TISTR 1462 and Clostridium beijerinckii TISTR 1461 were chosen to optimize acetone–butanol–ethanol (ABE) fermentation by using glucose as a carbon source. The enhancement in its productivity by adding various concentrations of ammonium acetate was studied. Then, the variation of glucose/xylose ratios in the pre-grown medium was(More)
Aflatoxin M1 (AFM1) is a toxic metabolite of the fungal product aflatoxin found in milk. For food safety concern, maximum residual limits of AFM1 in milk and dairy products have been differently enforced in many countries. A suitable detection method is required to screen a large number of product samples for the AFM1 contamination. In this study,(More)
Enrofloxacin is a fluoroquinolone antibiotic approved for the treatment of infections in animals. Because of the side effects to consumers of animal products, the maximum residue limits (MRLs) of enrofloxacin in animal tissues for consumption are regulated. In this study, a monoclonal antibody (mAb) against enrofloxacin was prepared and characterized for(More)
After 24 h of chemical permeabilization with 20% (v/v) methanol at 25 °C, the amount of daidzein released from soybean seeds is 15 to 20% of the amount (0.0423 6 0.0045 mg/g seed dry wt) obtained by physical grinding. With this chemical permeabilization condition, 70% of the permeabilized seeds are still able to germinate. The release of daidzein is(More)
Corncob is a potential feedstock in Thailand that can be used for fermentable sugar production through dilute sulfuric acid pretreatment and enzymatic hydrolysis. To recover high amounts of monomeric sugars from corncob, the sulfuric pretreatment conditions were optimized by using response surface methodology with three independent variables: sulfuric acid(More)
In Thailand, farmers often use oxytetracyline (OTC) to protect and treat shrimps from disease. The widespread use of OTC could lead to OTC residues in food-producing animal. To prevent consumers from exposure to drug residues and increasing in drug resistance pathogens, several regulatory authorities around the world have set the maximum residue limits(More)
Leptospirosis is a widespread zoonotic disease in tropical areas caused by pathogenic gram – negative spirochetes Leptospira spp., which affect both human and animals. The disease is transmitted by contacting urine of the infected animals. Leptospira penetrates through mucosa or open wound skin of infected individuals. Symptoms of leptospirosis are(More)
