Phosphorus is one of nature's paradoxes as it is life's bottleneck for subsistence on earth but
at same time is detrimental in surplus quantities in an aquatic environment. Phosphorus …

Phytases are hydrolytic enzymes that initiate stepwise removal of phosphate from phytate.
Phytate is the major phosphorous storage compound in cereal gains, oilseeds, and legumes …

We previously constructed three recombinant phyA mutant strains (PP-NP m-8, PP-NP ep-
6A and I44E/T252R-PhyA), showing improved catalytic efficiency or thermostability of …

Phthalic acid esters (PAEs) are widely used plasticizers found in consumer products, which
enter the environment and pose severe threats to human health. Here, a new PAE …

The last couple of decades have witnessed a true revolution in protein engineering that very
few could have foreseen, a revolution delivered by the hand of directed evolution. This …

Phytase efficiently catalyzes the hydrolysis of phytate to phosphate; it can be utilized as an
animal supplement to provide animals their nutrient requirements for phosphate and to …

Resistance to high temperature, acidic pH and proteolytic degradation during the pelleting
process and in the digestive tract are important features of phytases as animal feed. The …

As a feed additive, the desirable features of phytase include thermostability, strict substrate
specificity, and high stability in a wide pH range. Alkaline phytases from Bacillus subtilis are …

Aspergillus niger phytase (PhyA) has been used as a feed supplement to improve the
bioavailability of phytate phosphorus to swine and poultry. However, it is unable to maintain …

Furfural-tolerant strain is essential for the fermentative production of biofuels or chemicals
