Partial Purification and Characterization of β-glucosidase fromMonascus sanguineus BABT
Dikshit,Rashmi; Tallapragada,Padmavathi.
The aim of the present work was to study the production and characterization of β-glucosidase from Monascus sanguineus. Agro-waste residues were screened to obtain the maximum yield of enzyme. Jack fruit seed was the best substrate for enzyme production. Studies on the optimization of pH and temperature showed acidic pH favorable for enzymatic activity, whereas the optimum temperature was 60°C. Enzyme kinetics studies with different concentration of pNPG showed the calculated value of Km approximately 0.89 mM with the non-linear regression and 0.98 mM with the linear regression techniques. The enzyme was predominantly inhibited by KCl (69.8%) and moderately inhibited by CaCl2(14.8%). Studies on the sensitivity for glucose showed that after 100 mM...

Phosphate Solubilizers from the Rhizosphere of Piper nigrum L. in Karnataka, India Chilean J. Agric. Res.
Seshachala,Usha; Tallapragada,Padmavathi.
Black pepper (Piper nigrum L.) is a climbing vine known for its pungent fruit used as a spice worldwide. The aim of this study was to evaluate the available P content in the native soils where pepper is grown as a crop plant. The native population of phosphate solubilising microbes (PSM) was studied from the rhizosphere of P. nigrum plants grown in the Western Ghats of Karnataka, India. A variety of phosphate solubilising bacteria and fungi were isolated from the rhizosphere soil samples. Phosphate solubilising capacity of different isolates was studied on Pikovskaya's medium. The isolates were tested for their phosphate solubilising capacity in vitro with three different phosphate sources, tricalcium phosphate (TCP), potassium dihydrogen phosphate (KHP),...
