Department of Industrial Microbiology, Maria Curie-Skłodowska University, Lublin, Poland.

A novel method for enzymatic biotransformation of limonene to carvone has been developed. It involves addition glucose oxidase and peroxidase to the biotransformation medium. Some factors affecting biotransformation yield were investigated. Maximal yield of carvone occurred in the medium containing 1.5% substrate, at 50 degrees C and pH 7.0.

UI	MeSH Term	Description	Entries
D009195	Peroxidase	A hemeprotein from leukocytes. Deficiency of this enzyme leads to a hereditary disorder coupled with disseminated moniliasis. It catalyzes the conversion of a donor and peroxide to an oxidized donor and water. EC 1.11.1.7.	Myeloperoxidase,Hemi-Myeloperoxidase,Hemi Myeloperoxidase
D005421	Flavoring Agents	Substances added to foods and medicine to improve the taste.	Flavor Additives,Flavor Enhancers,Additive, Flavor,Additives, Flavor,Agent, Flavoring,Agents, Flavoring,Enhancer, Flavor,Enhancers, Flavor,Flavor Additive,Flavor Enhancer,Flavoring Agent
D005949	Glucose Oxidase	An enzyme of the oxidoreductase class that catalyzes the conversion of beta-D-glucose and oxygen to D-glucono-1,5-lactone and peroxide. It is a flavoprotein, highly specific for beta-D-glucose. The enzyme is produced by Penicillium notatum and other fungi and has antibacterial activity in the presence of glucose and oxygen. It is used to estimate glucose concentration in blood or urine samples through the formation of colored dyes by the hydrogen peroxide produced in the reaction. (From Enzyme Nomenclature, 1992) EC 1.1.3.4.	Microcid,Oxidase, Glucose
D000077222	Limonene	A naturally-occurring class of MONOTERPENES which occur as a clear colorless liquid at room temperature. Limonene is the major component in the oil of oranges which has many uses, including as flavor and fragrance. It is recognized as safe in food by the Food and Drug Administration (FDA).

D000081005	Cyclohexane Monoterpenes	Monoterpenes that include a cyclohexane ring in their structure.	Monoterpenes, Cyclohexane
D001711	Biotransformation	The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
D013729	Terpenes	A class of compounds composed of repeating 5-carbon units of HEMITERPENES.	Isoprenoid,Terpene,Terpenoid,Isoprenoids,Terpenoids
D053138	Cyclohexenes	Six-carbon alicyclic hydrocarbons which contain one or more double bonds in the ring. The cyclohexadienes are not aromatic, in contrast to BENZOQUINONES which are sometimes called 2,5-cyclohexadiene-1,4-diones.	Cyclohexadienes
D039821	Monoterpenes	Compounds with a core of 10 carbons generally formed via the mevalonate pathway from the combination of 3,3-dimethylallyl pyrophosphate and isopentenyl pyrophosphate. They are cyclized and oxidized in a variety of ways. Due to the low molecular weight many of them exist in the form of essential oils (OILS, VOLATILE).	Monoterpene,Monoterpenoid,Monoterpenoids
