A NEW <i>CHLOROSARCINOPSIS</i> FROM THE NEGEV DESERT

Abstract

SUMMARY Chlorosarcinopsis negevensis n. sp. f. negevensis and Chi. negevensis f . ferruginea n. f. have been isolated in culture from a desert locality in the Negev. The organisms form regular 3‐dimensional cell packets. Pseudofilamentous groups or a gelatinous matrix are absent. Reserve material is an orange‐colored oil formed in quantities. In old cultures, palmelloid stages appear. Reproduction is by zoospores, autospores, and isogametes. The sensitivity pattern of Chi. negevensis to inhibitory agents differs from that of the other species of the genus.
