Abstract: The present disclosure relates to a carbonic anhydrase complex and a method for preparing same, in which a conjugate of a carbonic anhydrase and a dockerin module is bound to a small cellulose binding protein including a cohesin module and a cellulose binding module (CBM) and method of manufacturing thereof. The complex, which includes a cellulose binding module, is immobilized on the surface of green algae, to increase access to a substrate and enzyme activity, thereby efficiently fixing carbon dioxide, and increasing the growth and lipid production of green algae without adding other carbon sources. The present disclosure is expected to be actively utilized in fields, such as biofuels, using carbon dioxide fixation.

Abstract: The present invention relates to an L-cysteine-producing mutant microorganism having introduced therein genes encoding enzymes which are involved in the L-cysteine metabolic pathway, and more particularly to an L-cysteine-producing mutant microorganism having introduced therein cysE, cysK and cysR, which are genes encoding enzymes which are involved in the L-cysteine metabolic pathway, and to a method of producing L-cysteine using the mutant microorganism. According to the present invention, L-cysteine can be produced with high efficiency as a result of regulating metabolic fluxes associated with the L-cysteine metabolic pathway of the mutant microorganism and regulating a system for supplying a sulfur source essential for synthesis of L-cysteine.

Abstract: The present invention relates to a mutant microorganism having the ability to produce 5-aminolevulinic acid, and more particularly, to a mutant microorganism having the ability to produce 5-aminolevulinic acid wherein a glutamyl-tRNA reductase-encoding gene is introduced in a glutamic acid-producing microorganism, and to a method for producing 5-aminolevulinic acid using the same. According to the present invention, 5-aminolevulinic acid that is useful in the medical or agricultural field can be produced in a significantly higher yield than that of conventional production methods.
