Recent results suggest that the presence of common nitrogen salts (sodium nitrite and nitrate) in the irradiation medium can markedly protect filamentous blue green algae from potentially lethal ultraviolet light irradiation. Our results as well as general biologica-l arguments as presented by Egami (above) support and extend Egami's original view that anaerobic respiratory pathways using nitrite and nitrate as terminal electron acceptors evolved prior to oxygen requiring aerobic respiratory pathways.
近期研究结果表明，辐照介质中常见氮盐（亚硝酸钠和硝酸钠）的存在能够显著保护丝状蓝藻免受可能致命的紫外线照射。我们的研究结果以及江见（上述）提出的一般生物学观点支持并拓展了江见最初的观点，即利用亚硝酸盐和硝酸盐作为末端电子受体的厌氧呼吸途径早于需氧呼吸途径进化而来。
