A novel alpha-acetolactate decarboxylase enzyme product with improved stability is provided. The novel enzyme is produced in high levels by cultivation of Bacillus strains selected from the group consisting of Bacillus brevis and Bacillus licheniformis ATCC 11031, ATCC 12759, ATCC 12713, ATCC 11946, ATCC 27326, NRRL B-3751, NCTC 2120, NCTC 8721, NCIB 6816, NCIB 8537 and NCIB 11868.

Alpha-acetolactate decarboxylase enzyme and preparation thereof

A novel protease product suitable for admixture to washing compositions and exhibiting substantially attenuated allergenic properties is prepared by cultivating strains of Bacillus licheniformis which have been mutated to block their synthesis of protease other than Subtilopeptidase A (subtilisin). The commercial Bacillus licheniformis derived protease products are mixtures of subtilisin and a non-serine protease of lower stability and greater allergenicity than subtilisin.

Protease product of reduced allergenicity

A beta-glucanase is prepared through the cultivation of Aspergillus phoenicis (Cda.) Thom or Aspergillus saitoi var Kagoshimaensis. This enzyme hydrolyzes the beta glucan of barley and can be employed to adjust the viscosity of wort and beer, through incorporation of the enzyme in mash or beer.
