| Abstract: | Frankia sp. LLR 02022, isolated from nodules of Casuarina cunninghamiana Miq., and its spontaneous mutant LLR 02023, show similar morphology but slight differences in cell chemistry and major differences in carbohydrate utilization. The mutant has the same phospholipids, phospholipid fatty acids and menaqmnones as the parent, but shows quantitative differences in peptidoglycan composition, pigment production and triglyceride fatty acids. The parent utilizes only rhamnose; the mutant also utilizes arabinose, glucose and xylose under certain conditions of growth. The significance of these findings is discussed. |
