Optimum conditions for protein extraction from tuna processing by-products using isoelectric solubilization and precipitation processes

The by-product from tuna processing is a potential source of edible protein. Therefore, it is very important to extract protein from such raw materials for human food. In this study the optimum pH for protein extraction from tuna by-products was optimized by using isoelectric solubilization and precipitation processes. The Response Surface Methodology (RSM) and the single factor model were used...

Cultivation Conditions for Phytase Production from Recombinant Escherichia coli DH5α

Response surface methodology (RSM) was used to optimize the cultivation conditions for the production of phytase by recombinant Escherichia coli DH5α. The optimum predicted cultivation conditions for phytase production were at 3 hours seed age, a 2.5% inoculum level, an L-arabinose concentration of 0.20%, a cell concentration of 0.3 (as measured at 600 nm) and 17 hours post-induction time with ...

Mineral phosphate solubilization activity of gluconacetobacter diazotrophicus under P-limitation and plant root environment

The ability to solubilize insoluble inorganic phosphate compounds by Gluconacetobacter diazotrophicus was studied using different culture approaches. Qualitative plate assays using tricalcium phosphate as the sole P-source showed that G. diazotrophicus produced solubilization only when aldoses were used as the C-source. Extracellular aldose oxidation via a pyrroloquinoline quinone-linked glucos...

Rock and Mineral Weathering Experiments under Model Venus Conditions

Introduction. Chemical analyses of rock and rego-lith at the Venera and Vega landing sites [1] suggest that Venus' surface consists of basaltic rocks with variable amounts of S, either as a primary constituent or as a secondary product of atmospheric interactions. Starting with these chemistries, models of Venus mineralogy predict that the surface is composed of primary basaltic minerals, unrea...
