In the present study, crude Calophyllum inophyllum oil (CCIO) has been evaluated as a potential feedstock for biodiesel production. C. inophyllum oil has high acid value which is 59.30 mg KOH/g. Therefore, the degumming, esterification, neutralization and transesterification process are carried out to reduce the acid value to 0.34 mg KOH/g. The optimum yield was obtained at 9:1 methanol to oil ...

Abstract The acid degumming waste of the seeds oil refining industry is currently disposed of, but, instead, it could be exploited as an important source for preparation many products. In this work, coming from soybean step was first recovered and treated, allowing isolation a fraction enriched phospholipids (PLs). Then, latter transformed, via enzymatic reaction catalysed by phospholipase D (f...

Regenerated silk fibroin has been proposed as a material substrate for biomedical, optical, and electronic applications. Preparation of the silk fibroin solution requires extraction (degumming) to remove contaminants, but results in the degradation of the fibroin protein. Here, a mechanism of fibroin degradation is proposed and the molecular weight and polydispersity is characterized as a funct...

Lipases and phospholipases are interfacial enzymes that hydrolyze hydrophobic ester linkages of triacylglycerols and phospholipids, respectively. In addition to their role as esterases, these enzymes catalyze a plethora of other reactions; indeed, lipases also catalyze esterification, transesterification and interesterification reactions, and phospholipases also show acyltransferase, transacyla...

Vegetables oils are renewables sources of ready availability with vast commercial employability. The application these oils, generally, requires refining procedures for the removal substances that make it unfeasible, such as phosphatides, proteins and free fatty acids. objective this study was to evaluate effect acid aqueous degumming on physical-chemical properties crude oil Mauritia flexuosa ...

Actinomycetes isolated from 10 different soil and compost samples were screened for production of pectinolytic enzyme activities when grown on pectin-containing solid and liquid media. Pectinolytic enzymes, detected by using plate diffusion tests with a medium containing ramie (Boehmeria nivea) plant material as the sole carbon source, were mainly pectate lyases, but low activities of pectinest...
