Biofumigation is a biocontrol method that uses volatile compounds to combat soil pathogens. We investigated a biofumigation process based on the green manure of Brassicaceae. These plants contain the glucosinolate-myrosinase system which releases inh

Biofumigation by Brassicaceae green manure or seed meal incorporation into soil is an ecological alternative to chemical fumigation against soil-borne pathogens, based on the release of glucosinolate-derived compounds. This study aimed at investigati

An outline for isolating sunflower lipoxygenase (SLO) from germinating seeds is described. With linoleic acid as substrate, SLO optimum pH was 6.2, the temperature of maximum activity was 35°C and the activation energy was 3.4 Kcal/mole. Nordihydrog

The presence in all Brassicaceae plant organs of high amounts of glucosinolates, and of the enzyme myrosinase that catalyses their hydrolysis, linked to the high biocidal activity of some glucosinolate enzymatic hydrolysis derivative products (mainly

Starting from homochiral 1,3-oxazolidine-2-thiones 1 , a two-step sequence led to homotopic 2,3-dihydro-oxazolo[2,3- b ]quinazolin-5-one derivatives 3 . The sequence was developed and studied regarding its scope and limitations.

Glucosinolates, natural compounds found in Brassicaceae, can easily be transformed into desulfo-glucosinolates by action of Helix pomatia sulfatase. The recombinant β-O-glucosidase from Caldocellum saccharolyticum does not catalyse glucosinolate deg

Bioactive compounds were produced from natural glucosinolates, secondary plant metabolites, using myrosinase (thioglucoside glucohydrolase EC 3.2.3.1) isolated from ripe seeds of Sinapis alba. The enzyme was immobilized on granular nylon 6.6 with the

Glucosinolate degradation products (GLDPs), mainly isothiocyanates, obtained by myrosinase-catalysed hydrolysis of glucosinolates (GLs), are an important group of natural bioactive substances. The fungitoxic activity of four GLDPs, chosen on the basi

Chiral 1,3-oxazolidine-2-thiones were prepared in enantiopure form from renewable resources through an enzymatic process involving immobilized myrosinase (thioglucoside glucohydrolase E.C. 3.2.3.1).
