Extraction of fibrinolytic proteases from Streptomyces sp. DPUA1576 using PEG-p...

Extraction of fibrinolytic protease from Streptomyces sp. DPUA1576 fermentation broth was performed using polyethylene glycol (PEG) – phosphate salts aqueous two phase system (ATPS). The influence of pH, PEG molar mass, PEG and phosphate concentrations on fibrinolytic protease partition coefficient (K) were evaluated by 24 full factorial design. Fibrinolytic protease partitioned preferentially to the (PEG)-rich...

Effect of pH and temperature on phytase and biomass production by submerged fer...

Phytase production and biomass was evaluated in present work by submerged fermentation with Aspergillus niger var. phoenicis URM 4924. Experimental assays were done under different conditions of pH (4.0 to 8.0) and temperature (25 to 35 ºC), and the influence of these variables on the responses was studied through a 22 central composite design and response surface methodology. Phytase and biomass production wer...

Polysaccharide from Anacardium occidentale L. tree gum (Policaju) as a coating ...

Policaju-based coatings were applied on “Tommy Atkins” mangoes and the effects of four different treatments on mango shelf-life were evaluated under storage condition at 4◦C and 82 % of relative humidity over 28 days. The surface tension of mangoes was found to be 29.04 mN m−1; the dispersive and polar components were 27.57 mN m−1 and 1.47 mN m−1, respectively, and the critical surface tension was 22.7 mN m−1. ...
