A Chl f-containing filamentous cyanobacterium was purified from stromatolites and named as Halomicronema hongdechloris gen., sp. nov. after its phylogenetic classification and the morphological characteristics. Hongdechloris contains four main carotenoids and two chlorophylls, a and f. The ratio of Chl f to Chl a is reversibly changed from 1:8 under red light to an undetectable level of Chl f under white-light culture conditions. Phycobiliproteins were induced under white light growth conditions. A fluorescence emission peak of 748 nm was identified as due to Chl f. The results suggest that Chl f is a red-light inducible chlorophyll.
从叠层石中纯化出一种含有 Chl f 的丝状蓝藻,并根据其系统发育分类和形态特征将其命名为嗜盐微菌属 hongdechloris 属,新种。Hongdechloris 含有四种主要类胡萝卜素和两种叶绿素,即 a 和 f。在红光下,Chl f 与 Chl a 的比值可从 1:8 可逆变化,在白光培养条件下 Chl f 的含量可降低至无法检测的水平。在白光生长条件下诱导藻胆蛋白。鉴定出 748nm 的荧光发射峰归因于 Chl f。结果表明,Chl f 是一种红光诱导型叶绿素。
