A homologue of the aspergillus velvet gene regulates both cephalosporin C biosynthesis and hyphal fragmentation in acremonium chrysogenum

Article Abstract:

The Aspergillus nidulans velvet (veA) is identified from Acremonium chrysogenum, the major producer of the beta-lactum antibiotic cephalosporin C. This study finding is significant for biotechnical process which requires a defined stage of cellular differentiation for optimal production of secondary metabolites.

Adopting selected hydrogen bonding and ionic interactions from Aspergillus fumigatus phytase structure improves the thermostability of Aspergillus niger PhyA phytase

Article Abstract:

The functional importance of the hydrogen bond network and ionic interaction in supporting the high thermostability of Aspergillus fumigatus phytase (Afp) and the feasibility of adopting these structural units to improve the thermostability of a homologous PhyA phytase are demonstrated.
