Amylolytic enzymes are metalloenzymes with up to six [Ca.sup.2+] atoms at the active site whose catalytic activity can be affected by mono- and divalent metals [35].
Studies on marine sediments revealed Streptomyces as potential producers of amylolytic enzymes. The marine isolate produced amylase enzyme which had maximum activity at pH 9.5 and temperature of 50[degrees]C.
To achieve the first goal, the specific activity of proteolytic, cellulolytic, and amylolytic enzymes was compared between males and females collected in winter, when males are in a resting, postreproductive period, whereas females, which do not feed during the summer ovigerous period, are developing ovaries and preparing for the next reproductive season (Ituarte et al.
