Phân tích họ gen β-Amylase ở cây đậu tương (glycine max) - Cao Phi BằngSUMMARY Beta-amylases (β-amylase, EC 3.2.1.2) belong to the glycosyl hydrolase family 14. These enzymes hydrolyze the 1,4--D-glucosidic linkages in starch-type polysaccharide substrates to remove successive maltose units from the non-reducing ends of the chains. Using in silico methods, showed that soybean -amylase was a multigenic family. A t...

Bio-Methane potential test for anaerobic codigestion of faecal sludge and sewage sludgeBMP batch tests have shown the FS was found to be a potential substrate for co-digestion and methane production with the SS from the municipal STPs with or without primary sedimentation tank. Addition of FS as a co-substrate provided the specific methane yield from 269.3 NmL CH4/gVSsub added when only WAS was digested which increased up to 294.8...

Research on harvesting of microalgae Chlorella sp. by electrochemical flotation method using corrosive electrodesLaboratory scale experiments were carried out to study the harvesting MAB by ECF process. Various parameters viz. anode current density, initial MAB concentration and electrolyte concentrations were studied. From that, the optimum ACD for the ECF process were found in the culture with MAB concentration of 0.74 g/L to be as 1.5 mA/cm2. The Farada...
