A dedicated vector for efficient library construction and high throughput screening in the hyphal fungus Chrysosporium lucknowense

A self-replicating vector was designed that enables the construction of complex libraries in the fungus Chiysosporium lucknowense. The circular vector is linearized in vivo and results in a transformation frequency up to 13,000 transformants/ug ofplasmid DNA. Upon prolonged cultivation of the transformants in liquid medium, the linearized vector...

Purification, cloning and characterisation of two forms of thermostable and highly active cellobiohydrolase I (Cel7A) produced by the industrial strain of Chrysosporium lucknowense

Two forms of cellobiohydrolase I (CBH I, Cel7A) were purified from the culture ultrafiltrate of a mutant strain of the fungus Chrysosporium lucknowense, an industrial producer of cellulases and hemicellulases. The enzymes had different molecular masses (52 and 65 kDa, SDS-PAGE data) but the same pI (4.5). Peptide sequencing showed that a single...
