An antifungal protein produced by Bacillus licheniformis strain BS-3 was purified to homogeneity by ammonium sulfate precipitation, DEAE-52 column chromatography and Sephadex G-75 column chromatography. The purified protein was designated as F2 protein, inhibited the growth of Aspergillus niger, Magnaporthe oryzae and Rhizoctonia solani. F2 protein was a(More)
Friable calli of Polygonum multiflorum Thunb have been induced in MS medium supplemented with 6-benzylaminopurine (6-BA) and kinetin (KT). Suspension cultures were initiated from friable calli by inoculating calli in liquid MS medium in shake flasks in the dark and 25 °C on an orbital shaker at 100 rpm. The maximum dry weight (DW, 7.85 g/L) and(More)
A new approach is described to quantify the number of enzyme molecules, such as Candia antarctica lipase B, that are displayed on the cell surface of Pichia pastoris. Enhanced green fluorescent protein (EGFP) and Candida antarctica lipase B (CALB) were fused and displayed on the surface of P. pastoris by linking to the anchor flocculation functional domain(More)
OBJECTIVE To study the effect of chemical modification of chymopapain with monomethoxypolyethylene glycol on enzymic activity and antigenicity. METHODS Under the substrate protecting and non-substrate protecting, the chymopapain (Cp) was modified with two types of mPEG derivatives mPEG1 and mPEG2. The average ratio of modified-NH2 was tested by(More)
AIM To investigate the effects of fungal elicitors on inophyllums production in suspension cultured cell of Calophyllum inophyllum Linn. METHODS The pathogen of leaf spot disease of C. inophyllum L. was isolated and prepared as fungal elicitor. The fungal elicitor was added to the medium with different concentrations and culture period. Their effects on(More)
