Evaluation on microalgae for the production of bio-chemicals and electricity.

Recent advancement in biophotovoltaic systems using microalgae, coupled with biorefinery approach, would improve economy-feasibility in production. The major concern is its commercial strength in terms of scalability, strain selection and extraction procedure cost. It must compete with conventional feedstocks such as fossil fuels.

Purifying and Characterizing Bacterially Expressed Soluble Lactate Dehydrogenase from for the Development of Anti-Malarial Drugs.

Plasmodium lactate dehydrogenase (pLH) is one of the enzymes in glycolysis with potential target for chemotherapy. This study aimed to clone, overexpress and characterize soluble recombinant lactate dehydrogenase from in a bacterial system. Synthetic lactate dehydrogenase (-LDH) gene was cloned into pET21a expression vector, transformed into strain BL21 (DE3) expression system and then incubated for 18 h, 20 °C with the presence of 0.

Gene expression of microbial gelatinase activity for porcine gelatine identification.

In order to invent a porcine gelatine detection device using microbial resources, bacterial enzymes with a preference towards porcine gelatine and their candidate genes were evaluated. Five (n = 5) bacterial strains isolated from hot spring water and wet clay, Malaysia were screened for their gelatinase activity. The gelatinase enzyme was extracted and purified using ammonium sulphate precipitation prior to performing gelatinase assay on porcine, bovine and fish gelatine medium substrates.
