Pigment levels have been measured in a number of wild strains and colour mutants of Myxococcus xanthus . The non‐carotenoid yellow pigment and carotenoid pigment contents changed according to growth temperature and phosphate concentrations in liquid media. The highest content of both types of pigment was observed at 28°C with all strains. A high phosphate concentration depressed pigment content in both wild and mutant strains at all temperatures, except with two colour mutants, where the pigments levels remained unchanged at 28°C and 33°C.
