Abstract:
The process of disinfecting at least one of food, human beings, animals and products to be brought in contact with same to combat microorganisms includes (a) providing a microbicidal composition comprised of an effective amount of at least one microbicide which is hydrolyzable at a pH-value ranging from about 6 to about 8.5 and is a long-chain alkyl ester compound having the general formula: ##STR1## wherein R.sup.I, R.sup.II and R.sup.III are hydrogen or lower alkyl groups having 1 to 4 carbon atoms, R.sup.IV is a long-chain alkyl group having 10 to 18 carbon atoms, R.sup.V is hydrogen or a group having the formula R.sup.VI N.sup.+ H.sub.3, wherein R.sup.VI is an alkylene group having 3 to 4 carbon atoms, A is a monovalent counter ion, and n is a number of cationic groups in the long chain-alkyl ester compound; and (b) exposing microorganisms to the microbicidal composition to inactivate the microorganisms. The compound may then be detoxicated by exposing it to a medium having a pH-value ranging from about 6 to about 8.5 to hydrolyze the ester bond and reduce the content of the compound to innocuous levels.
Abstract:
A prophylactic agent for controlling venereal diseases. As an active microbicidal component, the agent has an ammonium compound having hydrolyzable ester group.

Abstract:
The present invention relates to a process for the cultivation of chitin/chirosanrich, filamentous fungi with capacity to assimilate mannose as well as xylose, galactose, and glucose, wherein the cultivation of the filamentous fungi in a liquid medium extracted from wood in the production of paper whereupon the said filamentous fungi are recovered from the medium.
Abstract:
A metal working process employs a metal working fluid which is water-based and which is one of neutral and basic, the metal working fluid including a corrosion inhibitor in an amount ranging from 0.1 to 10% by weight; a lubricant selected from the group consisting of mono- or dicarboxylic acids or esters thereof having more than 10 carbon atoms, organic phosphate esters containing one or two hydrocarbon groups having 6-18 carbon atoms, and nonionic alkylene oxide adducts having a molecular weight above 400, and mixtures thereof; and an antimicrobially active amount towards fungi and bacteria of at least one alkanolamine compound having the following general formula ##STR1## wherein R is an acyclic hydrocarbon group having 8-14 carbon atoms, A is an hydroxyalkyl group having 2-4 carbon atoms, and X is one of hydrogen. The at least one alkanolamine compound prevents microbial degradation of water-based fluids when included therein.
Abstract:
Use of a long chain alkyl ester as a temporary microbicide at pH-values from about 6 to about 8.5. The long-chain alkyl ester has the formula ##STR1## where R.sup.I, R.sup.II, and R.sup.III are hydrogen or lower alkyl groups and R.sup.IV is an long chain alkyl group having 10-18 carbon atoms, R.sup.V is hydrogen or a group having the formula R.sup.VI N.sup.+ H.sub.3 where R.sup.VI is an alkylene group having 3-4 carbon atoms, A is a monovalent counter ion and n is the number of cationic groups in the ester compound. The ester exhibits a temporary microbicidal effect due to a hydrolytic reaction. As a consequence the toxic effect on human and animals cells and tissues will be low.
