Molecular characterization and expression of a phytase gene from the thermophilic fungus Thermomyces lanuginosus.

The phyA gene encoding an extracellular phytase from the thermophilic fungus Thermomyces lanuginosus was cloned and heterologously expressed, and the recombinant gene product was biochemically characterized. The phyA gene encodes a primary translation product (PhyA) of 475 amino acids (aa) which includes a putative signal peptide (23 aa) and propeptide (10 aa). The deduced amino acid sequence o...

Molecular Cloning and Characterization of a Chitinase Gene from the Thermophilic Fungus, Thermomyces lanuginosus-RMB

A chitinase gene from the thermophilic fungus, Thermomyces lanuginosus was amplified from the genomic DNA of the fungus, by PCR technique. The PCR product was cloned into pXcmkn12 vector by TA cloning technique and sequenced. The gene contained five introns and six exons. The deduced protein sequence coded for 390 amino acids and exhibited very high degree of similarity to other endochitinases ...

Carbon utilization profile of a thermophilic fungus, Thermomyces lanuginosus using phenotypic microarray

The thermophilic filamentous fungus, Thermomyces lanuginosus produces the largest amount of xylanase reported. In addition to this, it expresses large amount of other enzymes that have been used industrially or have academic interest. Thus, this fungus has a potential to be applied for biomass conversion to produce biofuel or other applications. In this study, the Biolog system was used to char...

Purification and characterization of an acidic, thermophilic phytase from a newly isolated Geobacillus stearothermophilus strain DM12

Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
