The present invention relates to novel microalgae with high productivity of loliolide, in which thesp. HS4 of the present invention can be used as a biological resource to produce loliolide due to its high biomass productivity and high loliolide content, and can be used as a pharmaceutical composition or cosmetic composition which requires loliolide derived fromsp. HS4.

Microalgae having high loliolide productivity

Provided is a high throughput photobioreactor. The high throughput photobioreactor includes: a chamber; a plate installed in the chamber and mounted with a plurality of wells; a plurality of light sources installed in the chamber and irradiating light toward the plate; a light quantity controller positioned on an upper part of the plate to make quantities of light irradiated to the plurality of wells different; and a temperature controller controlling a temperature of the plate.

High throughput photobioreactor

A method of detecting and quantifying various enzymatic activities using a constructed artificial genetic circuit GESS (genetic enzyme screening system) for sensing phenolic compounds and a method of screening a trace of activities of target enzymes from a metagenome using the artificial genetic circuit, thereby securing target enzyme genes. When the method for screening and quantifying target enzymatic activity is used, useful genes can be screened from various genetic communities, including environmental or metagenomic libraries, at a single cell level in high throughput (million/day). Further, the sensitivity of the genetic circuit to phenol derivatives and the expression thereof can be controlled, and thus the genetic circuit can rapidly sense and quantify various enzymatic activities. Thus, the method can be advantageously used in the protein engineering technology for enzyme modification. Particularly, it can quantitatively investigate enzymatic activity, and thus can be applied to molecular evolution technology.

Method of screening and quantifying various enzymatic activities using artificial genetic circuits

The present invention relates tosp. KB10 strain having properties of promoting growth of, which is an alga capable of producing biodiesel, and also enhancing production performance of biodiesel. Mores specifically, it relates to novelsp. KB10 strain which has properties of promoting growth ofused for biodiesel production and also enhancing content of C18 (i.e., oleate) corresponding to high quality biodiesel component as much as 900%. By using root colonizing bacteria like, it is possible to promote effectively the slow cell growth ofand increase as much as possible the oleate amount, which is a high quality biodiesel component. Further, by carrying out mixture culture using such bacteria, problems associated with contamination by other microorganisms during a process of producing biodiesel by culture in an outside environment can be dramatically solved.
