Abstract
FROM manured garden soil two strains of chitinovorous bacteria have been isolated on agar plates of the following composition: chitin (finely ground), 1 per cent; dipotassium hydrogen phosphate, 0.1 per cent; magnesium sulphate, 0.1 per cent; calcium chloride, 0.03 per cent; agar, 1.5 per cent, in tap water; pH 7. The chitin was made from shrimps; the procedure of Benton1 was mainly followed. Chitin thus prepared has a nitrogen content of 6.9 per cent and showed the characteristic X-ray diagram.
