identification of lipolytic activity in a multitrophic population grown in wool-scour effluent

a multitrophic population established in wool-scour effluent produced esterase activity with specificity to steryl, wax and triacylglyceryl esters. the wax esterase activity peaked just prior to the esterase activity toward cholesteryl oleate and p-nitrophenol palmitate. the activity was present in both the extracellular and cell membrane..

wool dyeing. what's new?

wool quality is enhanced through dyeing by modified procedures using ph 4 to 5, lower dyeing and mordanting temperatures, and the use of protective and antisetting agents in the dyebath. several methods are available for the application of chrome dyes with minimal environmental impact. advances in processes for dyeing loose stock, package..

a set for printed-circuit nodes repair

the equipment for printed-circuit nodes is described and technical characteristics are given. the set enables to realize the following repair operations: controlled soldering of joints; melting and removal (suction) of solder; holes boring in printed-cards and holes drilling up to 2.0 mm diameter, polishing and clearing of printed- card s..

lexicography versus terminology

during an astm committee on terminology (cot) meeting, one of the cot members made the comment that 'we are, after all, practicing lexicography.' the statement was quite innocent and not intended to antagonize any dye-in-the-wool terminologists on the committee, but nonetheless, it gave rise to some spirited debate. to be sure, there are ..

quantification of the effectiveness of some phosphonates on the enhancement of wool dyeing

a quantitative measure was reached for the enhanced wool dyeing by sandolan milling violet n-fbl in the presence of phosphonates. the increase in dye uptake percentage runs parallel to pk//a values of the applied phosphonates. (author abstract) 9 refs

industrial application of formed-in-place membrane ultrafiltration and automated membrane-forming in the treatment and recycle of rinse-water during the scouring of raw wool

fresh water consumption in the scouring of raw wool at a mill in south africa has been dramatically reduced by a combination of two factors, namely the purification and recycling of some of the wash water for reuse during rinsing, and the recycle of water from the firm's biological degradation ponds for use in the earlier stages of wool w..

high rate anaerobic digestion of wool scouring wastewater in a digester combined with membrane filter

the performance and sludge diminution property in wool scouring wastewater treatment of an anaerobic process in combination with an ultrafiltration membrane (ufm) was evaluated. with regard to tod removal, both mesophilic (37 $degree$ c) and thermophilic (53 $degree$ c) digestion, without ufm, showed the same trend of decreasing sharply f..

microwave heating: industrial applications (citations from the engineering index data base)

industrial uses of microwave heating are covered in these citations of worldwide research. the topics include industrial heating and drying for processes such as paper drying, vulcanization, and textile processing. equipment design and safety are also cited this updated bibliography was prepared by searching the 1970-may 1979 data base of..

microwave assisted dye fixation

the design of a combinational heating system comprising a tm//0//1//0 cavity and a steam chamber for the dye fixation of textiles in the form of tow or sliver padded with appropriate dyes, is described in detail. the effects of moisture content, type of dye/textile, depth of shade and temperature distribution on the electrical characteris..

saccharification of bamboo carbohydrates for the production of ethanol

bamboo carbohydrates were hydrolyzed with commercial amylases and a mixture of fungal culture broths containing cellulolytic and hemicellulolytic enzymes. the effects of cooking temperature and the size of fiber particles were also investigated. it was found that the higher the cooking temperature, the higher the rate of sugar formation a..
