The investigations reported in this thesis deal with two separate problems with regard to a species of Streptomyces; one is the identification of the organism, and the other is concerned with 2 carbon metabolism, in this case an examination of the metabolic pathways used by the organism in its utilisation of oxalate as sole carbon source.
The work has been carried out at Queensland University as Research Project No. 24O.
The metabolism of the Streptomyces is dealt with in the first section of the thesis. After a review of the present state of knowledge of 2 carbon metabolism, with particular reference to oxalate, the methods and results of experimental work are given. The second section deals with the currently very confused taxonomy of the Streptomyces, reports some peculiarities of this organism and covers the steps taken to identify this species of Streptomyces. A discussion of the results follows
each section. Where the work of other authors has been used, due reference has been made in the prescribed form.
