Novel lipolytic enzymes are provided having an optimum pH in the range of 8 and 10.5 which exhibit effective lipase activity in an aqueous solution containing a detergent at a concentration of up to about 10 g/l under washing conditions at a temperature of 60 DEG C or below and at a pH between 7 and 11. These lipases are useful in washing compositions, premixes and enzymatic detergent additives. They are obtainable from bacteria strains selected from Pseudomonas pseudoalcaligenes, Pseudomonas stutzeri and Acinetobacter calcoaceticus. Preferred strains are Ps. pseudoalcaligenes CBS 467.85, CBS 468.85, CBS 471.85, CBS 473.85 and ATCC 29625, Ps. stutzeri CBS 461.85 and Acinetobacter calcoaceticus CBS 460.85, and variants and mutants thereof.
