This paper is reporting the data of a preliminary study on heavy metals distribution in fluid and solid phases involved dry classified aluminium hydroxide production through Bayer process. For released phases, main source contamination bauxite its mineralogical soluble or insoluble alkaline solution. It was shown that predominant way to transfer contaminating elements particles occlusion very f...

•g Purified wax•h as isolated by Anderson (1929), is a complex lipid extracted with chloroform from cultures of acid fast bacilli. Extracting the purified wax with boiling acetone, Asselineau (1951) obtained a soluble portion termed •gWax C•h and an insoluble residue, the •gWax D•h fraction. Likewise, the alcohol-ether soluble part of acid fast bacilli was classified into several fractions. •gP...

THERE has been considerable discussion as to the best method to be adopted in isolating the reserve carbohydrate of yeast. In order to isolate the insoluble carbohydrate all other material of the cell must be brought into solution and with this object earlier workers have extracted yeast with solutions of KOH varying from 3 to 60 %. The residue contains the insoluble carbohydrate whilst the sol...

To investigate the genetic identities of the mucins secreted in cystic fibrosis (CF) airways, sputum was collected from five individuals. Samples were separated into gel and sol phases by high-speed centrifugation and the gel phase was extracted in 6 M guanidinium chloride. The 'insoluble' residue remaining after extraction of the gel phase was brought into solution by reduction/alkylation. Den...

Hydro-conversion of coal hydroliquefaction residue obtained from a 6t/day pilot plant of Shenhua Group in Shanghai was carried out under the hydrotreating condition. The coal hydroliquefaction residue and its product were extracted in sequence with n-hexane, toluene and tetrahydrofuran in a Soxhlet apparatus. The n-hexane soluble fractions increased with the increase of reaction temperature and...

Using fluorescent antibody staining, we have established the association of methionyl-tRNA synthetase with the endoplasmic reticulum in PtK2 cells. After Triton X-100 extraction, 70% of the recovered aminoacyl-tRNA synthetase activity was found in the detergent-insoluble fraction. This fraction of the enzyme remained localized with insoluble endoplasmic reticulum antigens and with ribosomes, wh...

UNLABELLED BACKGROUND It is necessary to develop efficient methods to produce renewable fuels from lignocellulosic biomass. One of the main challenges to the industrialization of lignocellulose conversion processes is the large amount of cellulase enzymes used for the hydrolysis of cellulose. One method for decreasing the amount of enzyme used is to recycle the enzymes. In this study, the re...
