Examples of substratesubstrate Methanogens are generally found in anaerobic, reduced environments where substrates are either provided by other anaerobic microorganisms or from geological sources. In the present experiment, the activity of serine proteinases was not detected in secretions even by using various fluorogenic synthetic substrates for serine proteinases. Similarly, concentrations of lactate are higher within the caeca and colons of ruminants given feeds high in readily fermentable substrates, particularly grains [11, 14].
