摘要： A mutant carotenoidogenic bacterium, comprising any of genes (a)-(c) below: (a) a gene encoding a protein comprising a mutant amino acid sequence in which at least the 225th amino acid residue in the amino acid sequence of 1-deoxy-D-xylulose 5-phosphate synthase of a carotenoidogenic bacterium has been substituted with other amino acid residue; (b) a gene encoding a protein comprising a mutant amino acid sequence in which at least the 305th amino acid residue in the amino acid sequence of decaprenyl diphosphate synthase of a carotenoidogenic bacterium has been substituted with other amino acid residue; and (c) both of the genes (a) and (b) above.

摘要： A method of obtaining eggs taking on the yolk color preferred by consumers, whereby cost reduction and stable supply of feeds can be achieved, is provided. Specifically, the present invention provides a formula feed for poultry, in which the content of corn is 50% or less and the content of astaxanthin from a dry powder of a bacterium is 1 to 8 ppm, and a method of obtaining eggs taking on a desired yolk color using the formula feed. According to the present invention, it becomes possible to provide a formula feed that can be stably supplied at low price without influence of seasonal and weather conditions. In addition, poultry eggs taking on a yolk color that satisfies the consumer preference can be provided at a lower price.
