Effect of some environmental parameters on fermentative hydrogen production by Enterobacter cloacae DM11.

abstract：:An active in vitro protein-synthesizing system has been developed from Rhodospirillum rubrum grown under either photosynthetic or heterotrophic conditions. A protease activity has been found in both of these systems, and this activity can be readily inactivated by treating the cells with KCl and phenylmethyl sulfonylf...
