Plectonema boryanum can grow in the dark with ribose, sucrose, mannitol, maltose, glucose, or fructose. Cell doubling times with 10 mM substrate are the following: 5 days with ribose, 6 days with sucrose or mannitol, 10 days with maltose, 12 days with glucose, and 13 days with fructose; with ribose plus 0.1% casamino acids it is 2.5 days. Dark-grown cells appear mophologically similar to light-grown cells. Cells grown in the dark for several years remain pigmented and resume photoautotrophic growth when placed in the light. Dim light (85 lux) increases the growth rate with ribose and with ribose plus casamino acids to nearly twice that of the dark rate. In the moderate light, growth takes place with ribose even in the presence of 1 times 10-5 MDCMU.
颤藻（Plectonema boryanum）可以在黑暗中利用核糖、蔗糖、甘露醇、麦芽糖、葡萄糖或果糖生长。以10 mM底物培养时的细胞倍增时间如下：核糖为5天，蔗糖或甘露醇为6天，麦芽糖为10天，葡萄糖为12天，果糖为13天；添加0.1%酪蛋白氨基酸的核糖培养时为2.5天。黑暗中生长的细胞在形态上与光照下生长的细胞相似。在黑暗中生长数年的细胞仍带有色素，置于光照下时可恢复光合自养生长。弱光（85勒克斯）能使核糖以及添加酪蛋白氨基酸的核糖培养时的生长速率提高至近黑暗生长速率的两倍。在中等光照下，即使存在1×10⁻⁵ M的二氯苯基二甲基脲（DCMU），颤藻仍能利用核糖生长。
