2,6-Diclhloroplleniolinidoplheol (D LP1P) is one of tlle mainy comnmloiinly) used electroni acceptors for the light-induced reactions in chloroplasts (2). Until recently, it has generally been assumed that it accepts electrons from the short-wavelengtlh pigment system 2 (PS2). Since the finding that indophenol reduction can be coupled with phlotophosphorylation [see review by Vernon and Avron (...

Van Niel's classical distinction between bacterial and green plant photosyntheses is based on the differences in the metabolism of the photooxidant (16). But direct measurement of the oxidizing power in bacterial photosynthesis is, at best, difficult with the usual spectrophotometric equipment. Light-induced oxidations of endogenous cytochromes have been demonstrated in whole cells and extracts...

The sensitivity improvement of a flow-injection spectrophotometric method for the determination of ammonia was examined based on an indophenol blue coloration reaction with salicylate and hypochlorite in the presence of manganese(II) as a reaction promotion catalyst. The optimal conditions for achieving higher sensitivity of ammonia determination were examined using a three-line flow system. Th...

Albino rabbits were used in the animal experiments and they were maintained on "Okara"•õ (300 g. daily). During the salt period sodium chloride was added to this and water intake was allowed ad libitum. In the human experiments a daily ascorbic acid intake was kept as constant as possible. The basal metabolic rate was measured by the Douglas Bags method. Total ascorbic acid content was determin...
