An alkalophilic fungal strain, Aspergillus versicolor PF/F/107 isolated from poultry farm produced alkaline protease at 40C and 9.0 pH. Protease showed compatibility with commercial detergents and retained 50-76% of its original activity at 40C in the presence of detergents in the following order: Ghadi, Ujalla, Surf excel, Ariel and Tide indicating its suitability for application in detergen...

Rat brain dipeptidyl aminopeptidases I to IV were assayed in the soluble and membrane-bound fractions of rat brain, and the effects of the detergents Triton X-100 and sodium deoxycholate on their activities were studied. Dipeptidyl aminopeptidases I and II were significantly inhibited in the presence of sodium deoxycholate, but were not affected by the presence of Triton X-100. However, dipepti...

Furthermore, it should be recognised that the dosage per wash of a detergent is one of the most important criteria for Ecolabelling. The necessity to have sufficient washing performance should avoid any deceit in Ecolabel application, e.g. recommending too low dosage in full knowledge that sufficient washing performance is not achievable and/or higher dosages will need to be used by the consume...

1. Lecithin, cephalin, and sphingomyelin prevent the inhibition of bacterial metabolism which is caused by synthetic anionic and cationic detergents. The phospholipids must be added either before or simultaneously with the detergent. Addition after the detergent is without effect. Bacteria still exhibit this phenomenon after they have been exposed to the phospholipid and thoroughly washed. 2. A...

In a previous paper it has been shown that the nonpolar-polar anionic detergents can be divided into two main groups. One chemically characterized by a relatively long chain of non-polar alkyl groups, which in solution are in contact with one end of a muscle and, locally adhering to it, produce a permanent negative injury potential. This is generally accompanied by a loss of excitability. The s...

The mode by which four nonionic detergents interact with integral membrane proteins was studied by relating detergent binding to characteristic detergent monolayer and micellar dimensions and to the surface area of the hydrophobic sector of the proteins. The detergents used (C12E8, Triton X-100, dodecyl-beta-D-maltoside, and dodecyldimethylamineoxide) are efficient membrane solubilizers, which,...

With rapid advancement in science and technology in the last few centuries, modifications in every aspect of life are continuously occurring. No doubt, these modifications are improving life standards but among them some are harmful for our health. Along with numerous benefits, side effects of formulated synthetic chemicals are needed to investigate further to develop alternatives with ideally ...

We have examined the role of the environment on the interactions between transmembrane helices using, as a model system, the dimerization of the glycophorin A transmembrane helix. In this study we have focused on micellar environments and have examined a series of detergents that include a range of alkyl chain lengths, combined with ionic, zwitterionic, and nonionic headgroups. For each we have...
