Boyce, Angela; Walsh, Gary – Biochemistry and Molecular Biology Education, 2005
Four mini-practicals are described in which the effects of temperature and pH on phytase activity are assessed, as well as the enzyme's thermostability and the effect upon stability of simulated digestive tract conditions. Phytase is routinely incorporated into monogastric animal feed to ameliorate the negative nutritional and environmental…

Boyce, Angela; Casey, Anne; Walsh, Gary – Biochemistry and Molecular Biology Education, 2004
Courses in introductory biochemistry invariably encompass basic principles of enzymology, with reinforcement of lecture-based material in appropriate laboratory practicals. Students undertaking practical classes are more enthusiastic, and generally display improved performance, when the specific experiments undertaken show direct relevance to…
