Investigation of sulfide removal using biofilter innoculated with sulfur oxidizing bacteria (SOB)
(International University - HCMC, 2017)Hydrogen sulfide (H2S) is an odor gas that is harmful to senses of human and the environment if the amount exceeds 7.5 mg/Nm3 (QCVN 19:2009/BTNMT). In this study, hydrogen sulfide was treated by three strains of Sulfur ... -
Evaluating the amount of lignin peroxidase and manganese peroxidase extracted from wood decay fungi
(International University - HCMC, 2017)Wood-decay fungi produce a wide variety of enzymes including lignin peroxidase (LiP) and manganese peroxidase (MnP). Lignin peroxidase and manganese peroxidase are the most significant ligninolytic enzymes beside laccase. ... -
Screen for aedes aegypti larva killing bacillus thuringiensis from soil samples
(International University - HCMC, 2017)Bacillus thuringiensis (Bt) are gram-positive, soil-dwelling, spore-forming, rod-shaped bacterial species possessing insecticidal properties. The objectives of this study were to screen for Aedes aegypti larva killing Bt ... -
Investigation of antimicrobial activities of Streptomyce isolates from soil in Ho Chi Minh city
(International University - HCMC, 2017)In order to survive in a highly competitive environment, Streptomyces genus of Streptomycetaceae family must produce secondary metabolites known as antimicrobial agents, notably antibiotics to inhibit or kill other ... -
Investigation of adverse drug reation (ADR) from electronic medical records (EMR) for type 2 diabetes patients
(International University - HCMC, 2017)Electronic medical records (EMR) is not only a great resource for patient information management but also for important and long term medical research. On this research EMR database of diabetes patients is used to find the ... -
Decolorization of aromatic dyes by wood decay fungi
(International University - HCMC, 2017)The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. Synthetic azo dyes are extensively used in textile industry and are not easily degraded into the environment due to their ... -
