Thermoluminescence (TL) from autotrophically and photoheterotrophically cultivated Chlamydobotrys stellata was measured. Strong TL was emitted at 30°C after acetatenutrition of the alga. DCMU enhanced this band, as also did ferricyanide. It also appeared after poisoning of the alga with NH2OH or ANT-2p. These observations suggest that an alternative donor to photosystem II and not the water-splitting system is responsible for the TL + 30 band.
测定了自养和异养培养的星状颤藻的热释光（TL）。在乙酸盐营养后，藻类在 30°C 时发出强 TL。DCMU 增强了这个带，铁氰化物也是如此。在用 NH2OH 或 ANT-2p 毒害藻类后，也出现了这个带。这些观察结果表明，负责 TL+30 带的是光系统 II 的替代供体，而不是水分解系统。
