Optimization of Red Pigment Yield from Monscus purpureus Solid State Fermentation (Isolation and Characterization of Monscus purpureus and Optimization of its Red Pigment Production)
Abstract: Natural pigments production is one of the important approaches recently for being natural and having therapeutic properties. Monscus purpureus was isolated from imported red yeast rice, characterized and propagated on local rice as solid state culture. Morphological characteristics which include colonies, ascosporous and conidial stage were used to identify the fungi besides its red pigment production. Red pigment was produced using 10% of seed culture of Monescus purpureus, incubated at …

Enhancement of Gas Sensitivity of Composites of Carbon Derived from Rubber Tree and SnO2 to Detect Ethanol Vapor at Room Temperature
Abstract: Films of composites of activated carbon powder prepared from saw dust derived from core of rubber tree (Hevea Brasiliensis) and tin oxide (SnO2) were fabricated using the doctor blade method. Carbon powder was activated using phosphoric acid at 500°C for 45 minutes. The weight ratio carbon/SnO2 varied from 0 to 12% in steps of 2. The structural, optical and morphological properties of films were investigated using XRD patterns, UV-visible spectrums …
