Lipid production by oleaginous microorganisms is a promising route to produce raw material for the production of biodiesel. However, most of these organisms must be grown on sugars and agro-industrial wastes because they cannot directly utilize lignocellulosic substrates. We report the first comprehensive investigation of Mucor circinelloides, one of a few oleaginous fungi for which genome sequ...

The high level of organic elements and nutrients in wet market wastewater (WMW) has raised public concerns. phycoremediation method, which utilizes microalgae, can be further valorized by converting it into various valuable potential bioproducts. production Scenedesmus sp. WMW was investigated as an ingredient for fish feeds this study. two natural plant-based coagulants, Cajanus cajan (pigeon ...

Microwave-heating method for catalyst preparation has been utilized recently due to its shorter operation time compared the conventional method. Glucose, a renewable carbon source can be partially carbonized and sulfonated via microwave heating which could result in highly potential heterogeneous carbon-based acid catalyst. In this study, impacts of carbonization sulfonation parameters during w...

An experiment demonstrating changes in the fatty acid composition of bacterial membranes from bacteria grown at 22 and 373C is described. The changes in composition con"rm expected generalizations. The isolation method is simple and provides samples of fatty acid methyl esters ready for gas chromatography-mass spectroscopy (GC-MS) analysis within about 1.5 h. Analysis by GC-MS involves the use ...

When hydroperoxides are thermally decomposed in the presence of unsaturated fatty acids, dimers are formed in amounts equivalent to the hydroperoxide present. The origin of these dimers has not been shown by any definitive experiment. Radioactively (14C) labeled materials now have been used to determine whether (1) two molecules of hydroperoxide react, (2) a hydroperoxide and an unoxidized fatt...

In the current research work, effect of microwave irradiation energy on the esterification of palm fatty acid distillate (PFAD) to produce PFAD methyl ester / biodiesel was intensively appraised. The PFAD is a by-product from refinery of crude palm oil consisting >85% of free fatty acid (FFA). The esterification reaction process with acid catalyst is needed to convert the FFA into fatty acid me...

Many Swedish regional transport authorities want bus fleets driven on renewable fuels. However, it may be difficult to know what technology, or combination of technologies, choose. There is a need for improved knowledge and supportive methods sustainability assessments that can support public procurement processes. In the companion article (Part I), multi-criteria assessment (MCA) method techno...

This research focuses on producing biodiesel through the transesterification process of Ceiba pentandra triglyceride acid using a CaO/Hydrotalcite (CaO/HTC) catalyst. study aimed to determine effect adding catalyst mass, mole ratio oil: methanol yield, and knowing FAME content yield highest impact mass kapok seed oil FFA conversion results. Kapok was transesterified for 2 hours at temperature 6...
