The invention provides liquid enzyme compositions which are physically and microbially stable. The compositions are used, for example, in beer brewing processes.

Stabilized liquid enzyme compositions for brewing

Peptide aldehydes containing a ureido group are effective as stabilizers for protease in a detergent composition, and as stabilizers for a second enzyme in a liquid composition with a protease.

Detergent composition

Peptide aldehydes or ketone derivatives are particularly efficient for stabilizing subtilisin-type proteases in aqueous compositions such as liquid detergents, including peptide compounds with OH-substituted phenylalanine aldehyde as the C-terminal residue.

Stabilized liquid enzyme compositions

The present invention relates to a liquid detergent composition comprising a surfactant, a subtilisin and a protease stabilizer that is 3-chlorobenzoic acid, 4-chlorobenzoic acid, 3-chlorophenylacetic acid, 3,5-dichlorobenzoic acid, 3-(3-chlorophenyl)propionic acid or their corresponding salts. The composition can further comprise a another enzyme that is a lipase, an amylase, a cellulase or mixtures thereof. The stabilizer can be present at a concentration of 0.001 to 20% w/w. The concentration of the subtilisin can be at least 1.5 g/L.

Stabilized subtilisin composition

The present invention relates to a liquid composition comprising an enzyme and a phenyl boronic acid derivative enzyme stabilizer of the following formula: ##STR1## wherein R is selected from the group consisting of hydrogen, hydroxy, C.sub.1 -C.sub.6 alkyl, substituted C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkenyl and substituted C.sub.1 -C.sub.6 alkenyl.

4-substituted-phenyl-boronic acids as enzyme stabilizers

The invention relates to a liquid composition which comprises an enzyme and a enzyme stabilizing component. The enzyme stabilizing component is a boronic acid derivative.

Boronic acid or borinic acid derivatives as enzyme stabilizers

Naphthalene boronic acids

Novel azacyclic compounds selected from the group consisting of ##STR1## wherein R.sup.1 is H or C.sub.1-6 -alkyl
