Purification and characterization of an alkalistable phytase produced by Rhizopus microsporus var. microsporus in submerged fermentation
(2019-06-01)
The filamentous fungus Rhizopus microsporus var. microsporus produces an alkaline phytase in submerged fermentation. This alkaline phytase was purified 83-fold with 1.9% protein yield. The molecular mass of the glycoprotein ...
Characterization of a Thermotolerant Phytase Produced by Rhizopus microsporus var. microsporus Biofilm on an Inert Support Using Sugarcane Bagasse as Carbon Source
(2016-06-01)
The Rhizopus microsporus var. microsporus biofilm was able to produce increased levels of an extracellular thermotolerant phytase using polyethylene and viscose as an inert support in both modified NBRIP medium and modified ...

Characterization of the Catalytic Structure of Plant Phytase, Protein Tyrosine Phosphatase-Like Phytase, and Histidine Acid Phytases and Their Biotechnological Applications
(2018-01-01)
Phytase plays a prominent role in monogastric animal nutrition due to its ability to improve phytic acid digestion in the gastrointestinal tract, releasing phosphorus and other micronutrients that are important for animal ...
Phytase production by Rhizopus microsporus var. microsporus biofilm: characterization of enzymatic activity after spray drying in presence of carbohydrates and nonconventional adjuvants
(Korean Soc Microbiology & Biotechnology, 2014-02-01)
Microbial phytases are enzymes with biotechnological interest for the feed industry. In this article, the effect of spray-drying conditions on the stability and activity of extracellular phytase produced by R. microsporus ...

Effect of supplementation with Escherichia coli phytase for broilers on performance, nutrient digestibility, minerals in the tibia and diet cost
(2019-03-01)
Although phytase has been researched, new enzymes have been produced, leading to different animal responses. In this scenario, the present study proposes to evaluate the inclusion of a bacterial phytase produced by Escherichia ...
Corn and soybean meal metabolizable energy with the addition of exogenous enzymes for poultry
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2009-03-01)
Two metabolism assays were carried out to determine corn and soybean meal metabolizable energy when enzymes were added. In the first trial, 35 cockerels per studied feedstuff (corn and soybean meal) were distributed in a ...
