polygalacturonic acid/atrophy

BACKGROUND Biotechnological applications of microbial pectate lyases (Pels) in plant fiber processing are considered as environmentally friendly. As such, they become promising substitutes for conventional chemical degumming process. Since applications of Pels in various fields are widening, it is

OBJECTIVE The aim of this study was to obtain improved strains of pectinolytic yeasts adapted to the conditions of an industrial fermentation process, which was continuously operated to convert citrus molasses into ethanol. RESULTS The starter yeast of the industrial fermentation process was a

Fusarium oxysporum f. sp. lycopersici, the causal agent of tomato vascular wilt, produces an array of pectinolytic enzymes, including at least two exo-alpha1,4-polygalacturonases (exoPGs). A gene encoding an exoPG, pgx4, was isolated with degenerate polymerase chain reaction primers derived from
