The effect of lignin degradation products liberated during chemical hydrolysis of lignocellulosic materials on xylose-to-xylitol bioconversion by Candida guilliermondii FTI 20037 was studied. Two aromatic aldehydes (vanillin and syringaldehyde) were selected as model compounds. A two-level factorial design was employed
The ability of two natural phenols to act as mediators of the recombinant Myceliophthora thermophila laccase (MtL) in eucalypt-pulp delignification was investigated. After alkaline peroxide extraction, the properties of the enzymatically-treated pulps improved with respect to the control. The pulp

The antihyperglycemic effect of syringaldehyde (1), purified from the stems of Hibiscus taiwanensis, was investigated in streptozotocin-induced diabetic rats (STZ-diabetic rats) showing type-1 like diabetes mellitus. Bolus intravenous injection of 1 showed antihyperglycemic activity in a dose-dependent manner in STZ-diabetic

On the basis of structural analysis of dihydrofolate reductase (DHFR) (cocrystallized separately with NADPH, dihydrofolate and NADPH, trimethoprim), compounds 2 and 3 were optimized for inhibition of DHFR. Appreciable tumor growth inhibitory activities of compounds 2 and 3 over 60
Journal of industrial microbiology & biotechnology, 38(1), 71-78 (2010-09-08)
The inhibitory action of acetic acid, ferulic acid, and syringaldehyde on metabolism of Candida guilliermondii yeast during xylose to xylitol bioconversion was evaluated. Assays were performed in buffered and nonbuffered semidefined medium containing xylose as main sugar (80.0 g/l), supplemented
