The objective of the present invention is to provide a particle detection device and a particle detection method that can individually and continuously detect a wide range of particles. The objective is achieved by a particle detection device including: a particle separation channel through which particles are separated according to particle sizes in a perpendicular direction to the flow of fluid; and two or more particle recovery channels that are connected to and branched from the particle separation channel, in which each of the particle recovery channels includes a particle detection unit that includes an aperture and an electric detector.

To provide a microorganism capable of producing a large amount of carotenoids, mainly astaxanthin, and to provide a method of producing carotenoids using the microorganism, a microorganism having improved carotenoid productivity is used, which is obtainable by breeding a carotenoid producingbacteria which is featured by producing 720 mg or more carotenoid per 1 L of culture medium. Also used is a method of producing carotenoids using the bacterium.
