Enzymes that are used as animal feed supplements should be able to withstand temperatures of 60 to 90degC, which may be reached during the feed pelleting process. The thermostability properties of three histidine acid phosphatases, Aspergillus fumigatus phytase, Aspergillus niger phytase, and A. nig...

Zusammenfassung:Enzymes that are used as animal feed supplements should be able to withstand temperatures of 60 to 90degC, which may be reached during the feed pelleting process. The thermostability properties of three histidine acid phosphatases, Aspergillus fumigatus phytase, Aspergillus niger phytase, and A. niger optimum pH 2.5 acid phosphatase, were investigated by measuring circular dichroism, fluorescence, and enzymatic activity.
