Alcaligenes faecalis var. myxogenes 10C3, which produces large amounts of succinoglucan and small amounts of curdlan, was genetically unstable and mutated spontaneously to a form producing more curdland than succinoglucan when stocked on nutrient agar slants. The mutation occurred in the absence of cell division when the cells were incubated in saline and was enhanced by treatment with N-methyl-N'-nitro-N-nitrosoguanidine, ethyl methane sulfonate, or ultraviolet light. Mutant strains were genetically stable and did not revert spontaneously for at least 1 year when stocked on nutrient agar slants.
粪产碱杆菌黏液变种10C3能产生大量琥珀葡聚糖和少量凝胶多糖，该菌株在遗传上不稳定，当接种在营养琼脂斜面上时会自发突变为产生凝胶多糖多于琥珀葡聚糖的形式。当细胞在盐溶液中培养时，在没有细胞分裂的情况下发生了突变，并且用N-甲基-N'-硝基-N-亚硝基胍、甲磺酸乙酯或紫外线处理会增强这种突变。突变菌株在遗传上是稳定的，当接种在营养琼脂斜面上时至少1年内不会自发回复突变。
