Aim: To investigate the effects of single and multiple additions of the oligosaccharide elicitors, obtained from alginate and locust bean gum, on penicillin G production and the transcript level of penicillin G biosynthetic genes. Methods and Results

Media optimisation was attempted for β-glucuronidase production from a newly and locally isolated (Oxfordshire, UK) fungal strain of Ganoderma applanatum . Both fungal growth and β-glucuronidase activity were found to be greatly affected by varying

A novel immobilisation system was developed for dye decolorisation using laccase produced by Ganoderma sp. KU-Alk4. The enzyme showed high efficiency in dye decolorisation when entrapped in Cu–Al and Cu-alginate beads. The former gave the highest a

A newly characterised Bacillus strain, Bacillus cereus SPV was found to produce PHB at a concentration of 38% of its dry cell weight in shaken flask cultures, using glucose as the main carbon source. Polymer production was then scaled up to 20 L batc

Physiological regulation of laccase production from Ganoderma sp. KU-Alk4, isolated in Thailand, was controlled by the initial glucose concentration in liquid culture. Different laccase isozymes were produced using different starting concentrations o

To engineer the production of laccase by Ganoderma sp. KU-Alk4, a newly isolated white-rot fungus, a seven-level Box−Behnken factorial design was employed to optimize the culture medium composition. A mathematical model was developed to show the ef

Penicillium chrysogenum spores were immobilised in kappa-carrageenan. The effect of the number of viable spores immobilised per bead on the rate of germination and degree of subsequent mycelial growth was investigated. The distribution of active myce

Mushrooms are greatly prized in oriental cultures because they are known to have more than one active role in traditional medicine. Current practice is to use whole mushroom preparations or simple water extracts. It is assumed that the active polysac

Activity of reactive oxygen species (ROS) was investigated in liquid cultures of Penicillium chrysogenum P2 supplemented with carbohydrates. Oligosaccharides lowered the ROS activity in all samples. The greatest effect occurred when oligosaccharides

Cyclodextrin glycosyltransferase (EC 2.4.1.19, CGTase) is an enzyme that produces cyclodextrins from starch via an intramolecular transglycosylation reaction. Addition of small amounts (10% v/v) of polar organic solvents can affect both the overall p
