THE microbial degradation of oxalate is relatively a rare phenomenon. During the last decade, however, some valuable information on the isolation and study of some more oxalate-decomposing organisms, mostly bacteria, has been reported. The work of Bhat and Barker1, Janota2, Muller3, Khambata and Bhat4,5 and Jayasuriya6,7 has contributed substantially in this direction. Nevertheless, there seems to be no published data available on the decomposition of oxalate by Streptomyces and, so far as we are aware, this is the first report on this subject.
