During ethanol fermentation, ethanol accumulates in the medium and becomes a significant stress factor for yeast. Trehalose and glycogen are major carbohydrate storages and presumably protect cells from such stress conditions. In this study, batch…
1 Scope This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures,…
The chemical characterization of crude oil fractions is important for the petroleum research and complex structure of crude oil residue keeps studies ongoing. An analytical method which gives the composition of residue is not available yet and a…
This work focused on the evaluation of extraction protocols using convective heating and HNO3 or HCl solutions regarding their performance towards fractionation analysis of mercury (inorganic and organic fractions) in oily sludge samples using cold…
Phytosterols, which are naturally occurring in plants, have excellent nutritional and health values on lowering both the blood cholesterol level and the risk of cardiovascular diseases. Edible oils are the main source of daily intake of phytosterols,…
