A surface-emitting laser device includes a transparent dielectric layer provided in an emitting region and configured to cause a reflectance at a peripheral part to be different from a reflectance at a central part in the emitting region. In the surface-emitting laser device, the thickness of a contact layer is different between a region having a relatively high reflectance and a region having a relatively low reflectance in the emitting region. The contact layer is provided on the high refractive index layer of an upper multilayer film reflecting mirror, and the total optical thickness of the high refractive index layer and the contact layer in the region having the relatively low reflectance is deviated from an odd number multiple of a one quarter oscillation wavelength of laser light emitted from the emitting region.

Disclosed is a method for determining the fatty acid synthesis pathway of a microorganism. Specifically disclosed is a method for determining the fatty acid synthesis pathway of a microorganism, which is characterized by producing degenerate primers for a fatty acid synthesis-related enzyme gene and determining the presence or absence of the fatty acid synthesis-related gene in the genome gene extracted from the microorganism using the degenerate primers. The sequences for degenerate primers for C20-elongase gene, which is a fatty acid synthesis-related enzyme gene, are ATHGARTWYTKBRTITTYGTICA (SEQ ID NO:1) and TARTRISWRTACATIADIAMRTG (SEQ ID NO:2), and the sequences for degenerate primers for ?4-desaturase gene are GGNCAYCAYCMITAYACNAA (SEQ ID NO:3) and TCDATYTGRTGIBWIARNCC (SEQ ID NO:4). The microorganism is one belonging to the class Labyrinthulea. Also specifically disclosed is a PCR primer set for use in the determination method. The method is useful as a method for screening a microorganism capable of synthesizing a fatty acid.
