✦ Synopsis

485 isolates were recorded from different localitlies between summer 1984 and spring 1985. Thesc isolates comprise five different genera with eight different species of purple non-sulfur bacteria: Rhodopt~eudomona.v was the most comnion genus a t ill1 sites and was represented by three species, H. acidophila, B. blastico, R. palustris. Rhodomicrohiurn was the second in frequency and was represented by H. vannielli only. This species was only recorded for khor sites.

Rhodocyclus was represented by two species, K. gelatinosus and R. tenuis. Rhodobacter and Rhodospirillum were represcnt,ed by one species each, Rhodobacter cn.psulatus and Rhodo.qppiri1l u m rubrun,. Khor sites were richer in number of isolates a n d genera of purple non-sulphur bacteria than the main body of AHDL. Some species were more common in winter and spring while others predominate in summer and autumn.
