- 中文摘要:
本室將分離自水田,分別屬於 Anabaena , Nostoc , Cylindrospermum , Calothrix , Scytonema 和 Hapalosiphon等屬之一些品系,經純化至無菌後加以培養保存。此文對於這些無菌之藍綠藻品系的形態、培養性質及固氮活性等加以討論。在 Anabaena , Nostoc 和Hapalosiphon之一些品系中有雙型性之現象存在。藍綠藻通常生長於偏鹼性之環境,但在各品系中,Anabaena HA410之最適 pH 卻為略酸性。
- 英文摘要:
Strains of Anabaena, Nostoc, Cylindrospermum, Calothrix, Scytonema and Hapalosiphon isolatedfrom rice field have been purified as axenic culture. The morphology, culture characteristics and the N2-fixing activity of these bacteria-free cultures were described. Dimorphism existed in some strains ofanabaena Nostoc, and Hapalosiphon. Among the isolates, Anabaena HA410 was different from the others by having the optimum pH at the slightly acidic condition.
