Cryptococcus gastricus Reiersöl & di Menna 1958

Description

Standard description of Cryptococcus gastricus:

Growth in malt extract: After 3days at 25°C. cells are round-oval to long-oval (3.5 - 6) x (5.5 - 11) µ, single or in pairs. After one month at 17°C. a thin ring and a sediment are formed.
Growth on malt agar: After 3 days at 25°C. cells have the same shape and size as in malt extract. The cells are surrounded by a capsule. "Starch" is produced. The streak culture after one month at 17°C. is yellowish-brown, slightly wrinkled in the middle with a smooth and lobated margin. The culture may be mucous.
Slide cultures: Some elongate cells are formed, but no pseudomycelium.
Fermentation: Absent.
Sugar assimilation: Glucose +, Maltose +, Galactose +, Lactose -, Saccharose -
Assimilation of potassium nitrate: Absent.
Ethanol as sole source of carbon: No growth.
Splitting of arbutin: Negative.

Latin

In musto maltato cellulae subovoideae aut longoovoideae (3.5 - 6) x (5.5- 11) µ, singulae aut binae. Sedimentum et anulus subtilis formantur. In agaro maltato formae et dimensiones cellularum eaedem sunt quae in musto maltato. In medium liquidis agarinisque cellulae capsula circumdatae sunt. Amylum formatur. Cultura (post unum mensem, 17°C.) flavifusca, it parte media parum crispulata, margine undulato et glabro, in parte interdum mucosa. Pseudomycelium nullum. Fermentatio nulla. In medio minerali cum glucoso, galactoso, maltoso crescit. Nitras calicus non assimilatur. In medio minerali cum alcohole aetylico non crescit.

Notes

The same species was earlier isolated in New-Zeeland by one of the authors (DI MENNA) from a soil near Dunedin. She recovered a total of six strains of the species.
