From: Bioconversion of vitamin D3 into calcitriol by Actinomyces hyovaginalis isolate CCASU- A11-2
Growth and vitamin D3 bioconversion activity profiles of the parent Actinomyces hyovaginalis isolate A11-2 in a laboratory fermenter, using different aeration rates. Vitamin D3 bioconversion activity was expressed in terms of amounts of calcitriol produced. Other applied culture conditions: Inoculum size of 2% v/v; uncontrolled initial pH of 7.8; a temperature of 30 °C (before substrate addition) and of 28 °C (after substrate addition); agitation rate of 200 rpm; vitamin D3 (substrate) was added two days after the beginning of main culture
