Morphology

Pelodictyon

CELLULAR

Staining	Gram-negative
Morphology	Cells rod-shaped to ovoid, occurring singly or in netlike or more or less spherical aggregates
Motility	Nonmotile.
Specialized structures	.Branching may occur as a result of ternary fission. Cells regularly contain gas vacuoles. Cultures or cell material is either green or brown. Photosynthetic pigments are located in the cytoplasmic membrane and the chlorosomes which underlie and are attached to the cytoplasmic membrane

Growth Parameters

Pelodictyon

PHYSIOLOGICAL

Tropism	phototrophic Photoautotrophic growth with sulfide or sulfur as electron donor.
Oxygen	Obligately anaerobic
pH
Temperature	15-30`C
Requirements	In the presence of reduced sulfur compounds and bicarbonate and., a number of simple organic substrates may be photoassimilated.
Products	Bacterio-chlorophyll c, d or e occurs as the major photosynthetic pigment, in addition to small amounts of bacteriocholorphyll a. Chlorobactene or isorenieratene is the major carotenoid component (Schmidt and Schiburr 1970; Gorlenko 1972). During sulfide oxidation, globules of elemental sulfur are formed outside the cells; the sulfur may be further oxidized to sulfate.
