PROBLEM TO BE SOLVED: To provide a tomographic image generation method and a tomographic image generation device with increased depth of light penetration.SOLUTION: A tomographic image generation method for generating a tomographic image includes: performing a depth scan at one point on a surface of a target body by using a light beam incident to the target body after passing through a spatial optical modulator; repeating depth scans at the same point for each of plural patterns of the spatial optical modulator, to obtain depth scan data for each of the plural patterns; generating a matrix R representing a vector space on the basis of a correlation of signal values of the depth scan data for each of the plural patterns; applying a predetermined matrix decomposition to the matrix R; separating a vector space represented as a sum of sub-spatial components into a noise sub-space and a signal sub-space by means of the matrix decomposition; reconstructing a vector space by using a component of the signal sub-space and/or a component of the noise sub-space; and generating a tomographic image on the basis of the reconstructed vector space.

Abstract:
The present invention relates to a gene construct which is capable of achieving efficient production of an antimicrobial peptide in a microorganism, and a method for efficient mass production and separation of an antimicrobial peptide using the same. The gene construct of the present invention has a translationally coupled configuration of two independent and separate cistrons which encode an acidic peptide and a basic antimicrobial peptide, each having an opposite charge, under the control of a single promoter. The translationally coupled acidic peptide and basic antimicrobial peptide undergo charge-charge interaction simultaneously with expression thereof to neutralize the potential cytotoxicity of the antimicrobial peptide, resulting in prevention of antimicrobial peptide-mediated killing of host microorganisms. In addition, a conjugate of the acidic peptide and the antimicrobial peptide can be separated without chemical or enzymatic treatment. Therefore, it is possible to achieve easy mass production of antimicrobial peptides from recombinant microorganisms.
