The objective of the present invention is to provide a method for remarkably reducing a critical micelle concentration of an anionic surfactant, which is used in a large amount currently, to reduce the amount to be used. Also, the objective of the present invention is to provide a surfactant composition of which whole critical micelle concentration is remarkably reduced and in which an amount of an anionic surfactant is reduced in comparison with the case of using an anionic surfactant only as a surfactant. The method for reducing a critical micelle concentration of an anionic surfactant according to the present invention is characterized in using a cyclic lipopeptide biosurfactant in combination with the anionic surfactant.


A PHA copolymer which is slowly crystallized is improved in crystallization speed to improve the melt workability of the PHA copolymer in working such as injection molding, film molding, blow molding, fiber spinning, extrusion foaming or bead foaming, thereby improving the resultant articles in productivity. A method for the improvement is a method for producing a PHA mixture, including the step of culturing a microorganism having both of a gene encoding a PHA synthase that synthesizes a copolymer PHA (A) and that is derived from the genus Aeromonas, and a gene encoding a PHA synthase that synthesizes a PHA (B) different in melting point from the copolymer PHA (A) by 10C or more to produce, in a cell of the microorganism, two or more PHAs different in melting point from one another by 10C or more simultaneously.

Problem to be solved is providing a crystalline silicon-based solar cell in which a plated metal electrode layer is formed on the entire back surface, while precipitation of an undesired metal, diffusion of a metal into a silicon substrate, and so on are suppressed. To solve the problem, a crystalline silicon-based solar cell according to the present invention includes a first intrinsic silicon-based thin-film (2), a p-type silicon-based thin-film (3), a first transparent electrode layer (4), and a patterned collecting electrode (11) on a first principal surface (51) of an n-type crystalline silicon substrate (1); and a second intrinsic silicon-based thin-film (7), an n-type silicon-based thin-film (8), a second transparent electrode layer (9), and a plated metal electrode (21) on a second principal surface (52) of the n-type crystalline-silicon substrate (1). On a peripheral edge of the first principal surface, an insulating region freed of a short-circuit between the first transparent electrode layer (4) and the second transparent electrode layer (9) is provided. The plated metal electrode (21) is formed on an entire region of the second transparent electrode layer (9).

It is an object solved by the present invention to provide an Agrobacterium with increased gene targeting efficiency. The present invention provides an Agrobacterium having a T-DNA nuclear translocation ability equivalent to that of a wild-type Agrobacterium and also having a T-DNA chromosomal insertion ability that is lost or reduced in comparison to a wild-type Agrobacterium.


The purpose of the present invention is to improve processability in the melt-molding by improving the slowness of crystallization that is a disadvantage of polyhydroxyalkanoate, which is slow to crystallize, and to improve processing speed. Provided is a polyester resin composition including a first polyhydroxyalkanoate and a second polyhydroxyalkanoate, wherein the melting point of the second polyhydroxyalkanoate in the polyester resin composition is observed at a temperature lower than the melting point measured for the second polyhydroxyalkanoate alone.
