Analysis of biodiesel by high performance liquid chromatography using refractive index detector.

High-performance liquid chromatography (HPLC) was used for the determination of compounds occurring during the production of biodiesel from karanja and jatropha oil. Methanol was used for fast monitoring of conversion of karanja and jatropha oil triacylglycerols to fatty acid methyl esters and for quantitation of residual triacylglycerols (TGs), in the final biodiesel product. The individual sample compounds were identified using HPLC.

Production and optimization of biodiesel using mixed immobilized biocatalysts in packed bed reactor.

Vegetable oils are used as raw materials for biodiesel production using transesterification reaction. Several methods for the production of biodiesel were developed using chemical (alkali and acidic compounds) and biological catalysts (lipases). Biodiesel production catalyzed by lipases is energy and cost-saving processes and is carried out at normal temperature and pressure.

Fermentative production and optimization of mevastatin in submerged fermentation using .

The main objective of the study is to enhance the mevastatin production using Plackett-Burman (PB) and central composite design (CCD) by in submerged fermentation (SmF). Eight nutrients were chosen for a PB design with 12 experimental runs. A maximum mevastatin production of 170.
