Abstract

This study was conducted to determine the capacities of 37 fungi to utilize various crown gall opines as their sole carbon and nitrogen source. One strain of Fusarium solani, two of Cylindrocarpon destructans, and six of Cylindrocarpon heteronema catabolized octopine, mannopine, octopinic acid, succinamopine, or a combination of these opines. One C. heteronema and one Fusarium dimerum strain grew only on succinamopine. None of the fungal isolates had the ability to grow on nopaline. The catabolism of opines by fungi was confirmed by the disappearance of the opine from the growth medium and by an increase in final mycelial dry weight with rising initial concentration of test substrate. This study thus shows that the catabolism of opines is not restricted to bacteria.

摘要

本研究旨在确定 37 种真菌利用各种冠瘿碱作为其唯一碳源和氮源的能力。其中 1 株茄病镰刀菌、2 株拟茎点霉和 6 株拟轮枝孢能够代谢瓜氨酸、甘露碱、瓜氨酸酸、琥珀酸吗啉或这些冠瘿碱的混合物。1 株拟轮枝孢和 1 株双曲孢菌只能在琥珀酸吗啉上生长。没有真菌分离物能够在胭脂碱上生长。真菌对冠瘿碱的代谢通过生长培养基中冠瘿碱的消失以及随着测试底物初始浓度的升高,最终菌丝干重的增加得到证实。因此,本研究表明,冠瘿碱的代谢并不局限于细菌。
