Acrobeloides ?maximus (Thorne, 1925) Thorne, 1937
CGC strain code:
C1, WCUG1, B1
Nebe, central Senegal: Sahel soil 5 km south of Diourbel along road Diourbel-Gossas.
Collected in January 1989 by Pierre Baujard.
Secernentea - Rhabditida - Cephalobina - Cephaloboidea - Cephalobidae
- Axenic: 3% yeast extract, 3% soy peptone, 0.5 µg/ml hemoglobin
- Monoxenic: E. coli on NA + 5mg/ml cholesterol + 1 mM CaCl2
+ 1 mM MgSO4 + 25 mM K-phosphate buffer (pH=6).
No survival after freezing in glycerin. Can be stored 6-12 months on slowly
desiccated plates; such plates can
probably be stored permanently in liquid nitrogen.
Freely available in axenic medium.

Apparently part of a species complex. Cultured specimens are morphologically
very close to e.g. the amphimictic sinistral strains PS1158 and PS2160
(A. bodenheimeri) and to the amphimictic dextral strain PS2052 (A.
camberenensis), but are parthenogenetic and have a higher reproductive
rate. Very rare males appear only in very crowded plates.
