Rsearch progress on breeding of pullulan high-yield strain without melanin / 中国生化药物杂志

ABSTRACT

Pullulan is a linear glucosic polysaccharide produced by the polymorphic fungus Aureobasidium Pullulans, which has long been applied for various applications in medical and food industry due to its security, stability and low adhesive ability.At present, the two problems in restricting pullulan industrial production are the low polysaccharide production and melanin secreted which is hard to erase completely, giving the following process some problem.As a starting point, this review article collects and analyzes the progress on the breeding of pullulan high-yield strain without melanin in recent years, in order to find more efficient strains breeding methods, laying a foundation for further breeding of pullulan high-yield strain without melanin.
