Glycerol oxidase is an oxidizing enzyme of glycerol characterized by its ability to oxidize glycerol in the presence of oxygen to form hydrogen peroxide and glyceraldehyde. This enzyme is produced by cultivation of a microorganism belonging to the genus Aspergillus or the genus Neurospora in a nutrient medium.

Glycerol oxidase II is an oxidizing enzyme of glycerol characterized by its ability to oxidize glycerol in the presence of oxygen to form hydrogen peroxide and glyceraldehyde. This action of the present enzyme is the same as that of the enzyme glycerol oxidase I disclosed in U.S. application Ser. No. 897,695 filed on Apr. 19, 1978. However, this enzyme has characteristic properties in substrate specificity, optimum and stable pH, optimum temperature for action, substrate affinity (Michaelis constant glycerol). This enzyme is produced by culturing a microorganism belonging to the genus Penicillium.

Creatinine desimidase is produced by fermentation of microorganisms belonging to the genera Brevibacterium, Corynebacterium, Pseudomonas and Arthrobacter. The enzyme is recovered from the microbial cells and culture liquor. The enzyme is used for the quantitative determination of creatinine in a sample.

Novel .beta.-phenoxy- or substituted phenoxy-ethanol compounds or esters thereof expressed by the formula ##STR1## wherein R.sup.1 is a hydrogen atom or an alkyl group, R.sup.2 is a hydrogen atom or a substituent, Y is --OH group or group ##STR2## R.sup.3 is an alkyl group, and n is an integer of 1 to 3. These compounds have juvenile hormone activities, and are useful for hormonal pest control and increased production of silkworm cocoons.
