Halophilic microorganisms thrive at elevated concentrations of sodium chloride up to saturation and are capable of growing on a wide variety of carbon sources like various organic acids, hexose and also pentose sugars. Hence, the biotechnological application of these microorganisms can cover many aspects, such as the treatment of hypersaline waste streams of different origin. Due to the fact th...

Luzhoulaojiao liquor is a type of Chinese liquor that dates back hundreds of years, but whose precise chemical composition remains unknown. This paper describes the screening of the liquor and the identification of its compounds using comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry (GC × GC/TOF-MS). Samples were prepared by both liquid-liquid extraction and sol...

Normal and acidotic rumen liquor samples from buffalo calves were subjected to various treatments and injected intraperitoneally to mice. The mortality rate was recorded up to 4B h of post injection. The toxic factors present in the acidotic rumen liquor were heat resistant and were found to be concentrated in the high centrifuged sediment. It was observed that the acidotic rumen liquor was abo...

In this work, the effect of Fenton's reagent on the degradation of residual Kraft black liquor was investigated. The effect of Fenton's reagent on the black liquor degradation was dependent on the concentration of H2O2. At low concentrations (5 and 15 mM) of H2O2, Fenton's reagent caused the degradation of phenolic groups (6.8 and 44.8%, respectively), the reduction of reaction medium pH (18.2%...

The Nigerian liquor trade provoked fierce debate: was it advancing development or fashioning an economy based on the unproductive consumption of alcohol? The liquor trade was caught between two prevailing colonial perspectives on African economic development: the Darwinian-based principle that Western civilisation had a duty to protect Africans from all bad external influences, and the civilise...

DETERMINATION OF SILICA OXIDE iron ores usually are found in intimate association with sllica and phosphorus compounds. heir quantitative separation and purification sometimes present difficult problems to the chemist. Silicic acids may represent various degrees of dehydration. They are exceedingly weak, but combine with metallic oxides and form some of the most stable , oxides in nature, the s...

A new system has been developed for removal of chloride contamination from kraft process liquors. The compact, skid-mounted system which utilizes ion exchange columns only 24 inches in height, is shown to be capable of removing 90-99% of the chloride from a wide variety of sources including dissolved ESP catch, oxidized white liquor, spent bleach scrubber liquors, spent ion exchange demineraliz...

In this work, the aim was to study distribution and accumulation of non-process elements (NPEs) in recovery cycle Finnish pulp mills look at whether geographical location (North vs. South) correlates with current NPE levels. addition, a comparison older similar measurements made an attempt analyze reasons behind differences most typical elements, aluminum (Al), silicon (Si), calcium (Ca), phosp...
