Development and Germination of Candida Albicans Chlamydospores in Relation to Age

Oxygen-labile ?(+) lactate dehydrogenase activity in Desulfovibrio desulfuricans

“…On the basis of its substrate spectrum the strain was assigned to D. desulfuricans. It is a rod-shaped organism which does not possess desulfoviridin and is therefore similar to D. desulfuricans strain Norway 4 [7]. The organism was grown in a synthetic bicarbonate-buffered medium according to Widdel [2] with 20 mM lactate as energy source.…”

An unusual strain of Desulfovibrio sp. from an Antarctic lake

“…The features which are different are: FESu lacks cytochrome b, can grow on ethanol, has a lower mol% G + C and divides by asymmetrical fission. In many ways, strain FESu behaves like a strain of Desulfovibrio desulfuricans, similar to strain Norway 4 [12] which also lacks desulfoviridin. However, the mol% G + C of FESu is some 10% lower than that of strain Norway 4.…”

“…However, anomalous strains have been reported in the literature over this period [e.g. 2,3,5,12,[15][16][17][18]. Some reservations on the present system have been expressed by Postgate [1,5].…”

The Chlamydospore of Candida albicans.

“…A number of papers has been written not only about the germination of csp, the production and staining behaviour of catenulate csps and suspensor cells but about their ultrastructure as well (1,2,7,10,11,12). The general opinion is that the csp is either a resting structure, or a storing structure, or a reproductive cell (2,3,14,15).…”

“…Jansons et al adopted a complex procedure to obtain numerous csps: after washing them from the surface of pure agar layered on dialysing membrane they were filtered and liophylized till experimental use (5). After a lot of previous staining trials (7,11) Akisada et al applied 1 '/o (w/v) cotton blue in 3 % (v/v) aqueous acetic acid (1,2). They drew conclusions from these staining results concerning the possible selective staining of csps.…”
