Efficiency of fractionated γ-irradiation doses to eliminate vegetative cells and spores of Bacillus cereus from raw rice
Mtenga, Adelard; Kassim, Neema; Shim, Won-Bo; Chung, Duck-Hwa (2013-04-30)Efficacy of fractionated γ-irradiation to eliminate vegetative and spore forms of Bacillus cereus from raw rice was studied. Viable bacteria and spores count performed after irradiation treatment revealed that vegetative ... -
Occurrence of patulin in various fruit juices from South Korea: An exposure assessment
Cho, Mi Sook; Kim, Kyeongyeol; Seo, Eunkyoung; Kassim, Neema; Mtenga, Adelard B.; Shim, Won-Bo; Lee, Soo-Hyung; Chung, Duck-Hwa (Springer Nature Switzerland AG., 2010-02-28)To determine patulin in various fruit juices, high performance liquid chromatography (HPLC) method was optimized and validated. For validation of HPLC method, a linearity, accuracy, precision, detection limit, and ... -

Kassim, Neema; Mtenga, Adelard B.; Lee, Won-Gyeong; Kim, Jeong-Sook; Shim, Won-Bo; Chung, Duck-Hwa (Springer Nature Switzerland AG., 2011-12-31)Production of chicken immunoglobulins Y (IgYs) and their applications in prophylactic, therapeutic, detection of microbial contaminants and as a diagnostic tool has been widely studied with limited information from other ... -
Production of mouse anti-quail IgY and subsequent labeling with horseradish peroxidase using cyanuric chloride.
Kassim, Neema; Mtenga, Adelard; Shim, Won-Bo; Chung, Duck-Hwa (J. Microbiol. Biotechnol, 2013-04-01)Polyclonal antibodies labeled with a tracer have been commonly used as secondary antibodies in immunochemical assays to quantify the concentration of antibody-antigen complexes. The majority of these antibodies conjugated ... -
Resistance of Bacillus cereus and its enterotoxin genes in ready-to-eat foods to γ-irradiation
Mtenga, Adelard B.; Kassim, Neema; Lee, Won-Gyeong; Shim, Won-Bo; Yoon, Yohan; Chung, Duck-Hwa (Springer Nature Switzerland AG., 2012-04-30)This study was investigated the resistance of Bacillus cereus ATCC 13752 and its enterotoxin coding genes in cereals, vegetables, and tryptic soy broth to γ-irradiation. Screening for enterotoxin coding genes, viability ...
