摘要
研究了磷酸盐、镁离子和光照对橙色粘球菌（ＭｙｘｐｃｐｃｃｕｓｆｕｌｖｕｓＦＣ１０）色素形成的影响。橙色粘球菌产生吸收峰分别在４７２ｎｍ和３５５ｎｍ的类胡罗卜素和非类胡罗卜素两类色素。随着磷酸盐浓度（０，１０，２０，３０ｍＭ／Ｌ）升高，菌体非类胡罗卜素减少，与此同时类胡罗卜素增加。菌体非类胡罗卜素也随着镁离子浓度升高（硫酸镁含量０，０．１％，０．２％，０．３％）而减少。０．１％硫酸镁最适宜菌体类胡罗卜素的合成，硫酸镁浓度继续升高，类胡罗卜素的产生也受到抑制。光照不影响菌体类胡罗卜素形成，但非类胡罗卜素形成略有减少。
The effects of phosphate, Mg2+ and exposition on pigmentation of Myxococcus fulvus FC10 were studied.The carotenoid and noncarotenoid pigments (aborption maximum around 472nm and 355nm respectively) werefound from the crude pigment extracts of FC10 strain. While carotenoid content increased with the increasing of phosphate concentration(0, 10, 20, 30mM/L, the noncarotenoid content was inhibited. The noncarotenoid content decreased as the Mg2+ concentration (0, 0.1%, 0.2%, 0.3%) increased. For carotenoid formation of FC10, 0.1% ofMg2+ was the optimum concentrattion, and it was inhibited by Mg2+ concentration higher. Exposition was no effecton carotenoid content of FC10, but it decreased noncarotenoid slightly.
