Nutritional studies on some members of mucorales. VI

Utilization of different sulphur compounds
  • A. K. Sarbhoy


Sulphur requirements of six different species viz.,Absidia orchidis (Vuill.)Hagem,Absidia sp.,Actinomucor elegans (Eidam)Benjamin &Hesseltine,Cunninghamella bertholletiaeStadel,Chaetocladium hesseltiniiMehrotra &Sarbhoy andMortierella indicaMehrotra were studied.

Out of the nineteen various sulphur compounds tried sulphate, sulphite and bi-sulphate were utilized satisfactorily by all the six species.

Potassium hypo-sulphite was good forAbsidia sp. andCunninghamella bertholletiae, while for the rest it was a moderate source. Sodium bi-sulphite supported good growth ofAbsidia sp., poor ofC. hesseltinii but for the rest it was moderate.

Meta bi-sulphites of sodium and potassium responded differently in all the above six species. Potassium and sodium thio-sulphates were more or less mediocre sources for all the species exceptAbsidia sp. andC. hesseltinii in which case these were favourable.

Among the organic sources of sulphur thio-urea was found to be good forC. hesseltinii and moderate for the remaining species. Cystin and methionine supported moderate growth of all the species with the exception ofC. bertholletiae for which cystin was a poor source.

There was no correlation between the growth and sporulation for the species.

In all the cases growth was accompanied with the acidification of the media.
