Abstract:
The invention relates to enzyme preparations containing novel proteolytic enzymes produced by cultivation of novel species of the genus Bacillus and showing useful activity at high alkalinities. The invention also relates to production of the novel proteolytic enzymes by cultivation of the novel species of the genus Bacillus in a nutrient medium having a pH-value within the range of 7 to 12. Finally the invention relates to a process of isolating the novel species referred to by effecting the isolation on nutrient media having a pH-value within the range of 9 to 11. The novel enzymes are particularly useful in detergent and dehairing compositions.
Abstract:
IN WHICH R is hydrogen or OR1; R1 is hydrogen, benzyl, lower alkyl or cycloalkyl; R2 is hydrogen, lower alkyl, cycloalkyl, cycloalkyl containing a hetero atom, or OCR3; R3 is hydrogen, lower alkyl or CH2SO2X; X is chlorine, OR4, or OMe; R4 is hydrogen or lower alkyl; R5 and R6 are hydrogen or lower alkyl, or R5 and R6 together with the attached N-atom form a heterocyclic ring; and Me is an alkali metal or an earth alkali metal atom, useful anti-fertility compositions for oral administration, as well as processes for their production.

Abstract:
A method of making proteolytic enzyme preparations having maximum activity at high alkalinity by submerged aerobic cultivation of strains of Bacillus alcalophilus in a nutrient medium containing assimilable carbon and nitrogen sources, while maintaining the pH-value of the nutrient medium between 7.5 and 11.
