Abstract: An ink including water, a water-soluble organic solvent, a resin-coated pigment coaled with a resin (A), and a resin emulsion including a resin (B) is provided. The resin (B) has the same composition as the resin (A) and a volume average particle diameter of from 8 to 19 nm. The total content rate of the resin (A) and the resin (B) in the ink ranges from 2% to 11% by mass. The content of the resin (B) ranges from 30% to 55% by mass of the total content of the resin (A) and the resin (B).

Abstract: A new species of the genus Hyphogyma is disclosed, as are new lipases obtainable therefrom, Also disclosed is a process for obtaining the enzymes.

Abstract: A highly alkaline, positionally non-specific lipase can be obtained from the strains of streptomyces, cluster 1. Strains of cluster 1 of Streptomyces were not previously known to produce lipase. The lipase preparation has more than 50% of its optimum activity at pH 10 and is useful, e.g. in detergents.
