Summary of "Efficient approaches to convert Coniochaeta hoffmannii lipids into biodiesel by in-situ transesterification."

Coniochaeta hoffmannii was isolated from soils contaminated with biscuit factory wastes showed the maximum lipid accumulation capacity in the study. Lipid production was optimized in terms of pH, carrot pomace loading, nitrogen type and amount, incubation time. Solvent, alcohol type and catalyst concentration, dried/wet biomass concentration, reaction approaches and time were optimized for lipid extraction and transesterification. The highest lipid accumulation was found as 52.0% at pH 4 in the presence of 10% carrot pomace, 0.5 g/L cheese whey at the end of the 48 h incubation. The maximum total C16 and C18 FAME rates were detected at the 25 °C, in the presence of 4 g/L dried C. hoffmannii biomass, methanol and 3% NaOH by using the in-situ transesterification process at the end of the 0.5 h as 96.3%. This is the first report about the usage of C. hoffmannii lipids obtained from carrot pomace for sustainable biodiesel production.

Medical and Biotech [MESH] Definitions

The metabolic process of breaking down LIPIDS to release FREE FATTY ACIDS, the major oxidative fuel for the body. Lipolysis may involve dietary lipids in the DIGESTIVE TRACT, circulating lipids in the BLOOD, and stored lipids in the ADIPOSE TISSUE or the LIVER. A number of enzymes are involved in such lipid hydrolysis, such as LIPASE and LIPOPROTEIN LIPASE from various tissues.

Lipids, predominantly phospholipids, cholesterol and small amounts of glycolipids found in membranes including cellular and intracellular membranes. These lipids may be arranged in bilayers in the membranes with integral proteins between the layers and peripheral proteins attached to the outside. Membrane lipids are required for active transport, several enzymatic activities and membrane formation.

Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

Therapeutic approaches that are limited, gradual, or well-established as opposed to radical methods.

Comparison of outcomes, results, responses, etc for different techniques, therapeutic approaches or other inputs.
