生活在同一水体中的光合硫细菌（Chromatiaceae和Chlorobiaceae）竞争可利用的光。在Siso湖，一个小的缺氧的完整的Banyoles（赫罗纳，西班牙）附近的湖泊，竞争平衡的季节性变化取决于物理化学梯度和光。这两组细菌的最大总数全年都是互补的。在夏季，表面附近的活动Chromatium板的存在对生长在下面的Chlorobium种群起到生物滤光器的作用。后者通过增加特定色素含量和类胡萝卜素/细菌叶绿素比率来适应修改的光谱和强度。
Photosynthetic sulfur bacteria (Chromatiaceae and Chlorobiaceae) living in the same water body compete for available light. In Siso lake, a small anoxic holomictic lake near to Banyoles (Girona, Spain), the competitive balance changes seasonally depending on physicochemical gradients and light. Maximum total numbers of both groups of bacteria are complementary throughout the year. In summer time, the presence of motile Chromatium plates near the surface act as a biological light filter on the Chlorobium populations growing below. The latter adapt to the modified light spectrum and intensity by increasing both the specific pigment content and the carotenoid/bacteriochlorophyll ratio.
