An object of the present invention is to provide a method for microbioiogically producing astaxanthin of high concentration at low cost while suppressing production of canthaxanthin. Specifically, the present invention relates to a method for producing carotenoids including astaxanthin comprising culturing a bacterium that concurrently produces astaxanthin and canthaxanthin in a medium containing biotin, wherein a ratio of concentration of produced canthaxanthin to concentration of produced astaxanthin in a culture product after the end of culture in the medium is lower than that in a culture product alter the end of culture in a biotin-free medium.

A film member having a concave-convex structure is composed of a base member; a gas barrier layer formed on the base member; and a concave-convex structure layer formed on a surface of the gas barrier layer, wherein the surface of the gas barrier layer is formed of an inorganic material which is same as a material of the concave-convex structure layer, and the concave-convex structure layer is obtained from a precursor solution applied on the gas barrier layer. The film member having the concave-convex structure has an excellent adhesion property between the concave-convex structure layer and the gas barrier layer, and a high barrier property.


Provided are a petroleum needle coke having a sufficiently low coefficient of thermal expansion (CTE) and achieving suppression of puffing and a method of producing the petroleum needle coke. Specifically provided is a petroleum needle coke for a graphite electrode. A powder of the petroleum needle coke having a grain size of 75 m or less is heated at 2,800C in an argon gas atmosphere to yield a graphite powder having a loop structure that is formed by folding a stack including a plurality of stacked graphite crystal sheets, the graphite crystal sheet includes carbon atoms arranged in a plane, the graphite powder has an edge surface of the closed loop structure of the stack, and a loop formed by two adjacent layers on an innermost periphery of the stack has a stack angle of 5 or less. The stack angle is an angle formed by a tangent line at a point A and a tangent line at a point B, where each of the point A and the point B is 10 nm apart from a vertex of the loop and on the corresponding layer of the two adjacent layers along the basal plane, and the vertex of the loop is an outermost point on the edge surface of the loop on the innermost periphery.
