摘要
发菜(Nostoc flogelliforme)系一种陆生食用蓝藻,迄今不能人工栽培。实验室培养发菜获得初步成功,是最终解决该难题迈出的重要一步。水份是影响发菜生长的重要限制因子之一。直接原因是在水份条件好的情况下,由于微生物的大量繁殖,最终导致发菜个体解体而死亡。在基本了解并掌握有关发菜生态学特性和生物学特性的基础上,改进培养技术,就可使发菜在常规培养基上正常生长,培养14天,平均生长0.7—1厘米。
The Nostoc flagelliforme is a kind of edible blue algae and had not been cultivated artificially. The initial success in its artificial cultivation in the laboratory is reported in the paper. Water is one of the important restrictive factors that affect the growth of the algae. When there is much water,the algae would die due to fast propagation of bacteria in them. According to some basic work in ecology and biology of the algae the cultivation technique can be improved. Thus they can grow normally on conventional medium. When the algae are cultivated for 14 days, they can grow about 0. 7-1.0 cm in the average.
