Abstract: According to an aspect of the present disclosure, there is provided a substrate treating apparatus comprising: a vessel part having a substrate treatment region formed therein and including a supply port through which a treating fluid is supplied to the substrate treatment region and an exhaust port through which the treating fluid is exhausted from the substrate treatment region; a fluid supply unit configured to supply the treating fluid to the substrate treatment region; an exhaust unit configured to exhaust the treating fluid from the vessel part. The exhaust unit comprises: a main line connected to the exhaust port; an extension line branched from at least one of first and second nodes of the main line and including at least one of a first orifice or a first check valve to control an exhaust speed; and an auxiliary line branched from a third node of the main line, where an orifice and a check valve are not formed.

Abstract: The inventive concept provides a substrate treating method. The substrate treating method includes pre-treating a substrate by cleaning the substrate; etching the substrate by supplying an etchant and heating a substrate supplied with the etchant; and post-treating the substrate after the etching the substrate, and wherein the pre-treating the substrate, the etching the substrate, and the post-treating the substrate are each performed in different chambers, a substrate on which the pre-treating the substrate is completed is transferred in a dry state to a chamber at which the etching the substrate is performed, and a substrate on which the etching the substrate is completed is transferred in a wetted state with a liquid to a chamber at which the post-treating the substrate is performed.

Abstract: A cassette for ultra-thin glass includes a pair of plates spaced apart from and facing each other, and a plurality of supports mounted between the pair of plates and including a plurality of mounting grooves that support sides of sheets of ultra-thin glass. Each of the plurality of mounting grooves includes an inclined portion inclined toward a middle of each of the plurality of mounting grooves, and a straight portion extending from the inclined portion and having a constant width in an axial direction of the plurality of supports. A height of the straight portion in a radial direction of the plurality of supports is equal to or greater than a height of the inclined portion in the radial direction.

Abstract: The present invention relates to a novel gene derived from a tidal flat metagenome, and a novel protein obtained therefrom showing the coactivity of phospholipase and lipase. Specifically, the novel gene isolated from the metagenome library of tidal flat sediments and the protein having phospholipase and lipase activities encoded from the novel gene: are expressed in a water-soluble form to be mass-producible; enable ultra high-purity protein to be obtained through single step purification using an Ni-NTA column; show good activity in the pH range of 5˜10; maintain good low temperature activity and stability up to a temperature of 3° C. to 40° C.; and have high resistance against various organic solvents. Therefore, the novel gene and the protein can be usefully used for various industrial fields such as the purification and conversion of oil and fat, bio-medicine, and fine chemistry.

Abstract: Disclosed herein are ammonia-specific 5?-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5?-XMP aminase. The resulting 5?-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5?-XMP into 5?-GMP. Thus, the ammonia-specific 5?-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5?-XMP into 5?-GMP.

Abstract: Disclosed herein are mutant strains, KCCM-10784P and KCCM-10785P, which are obtained through gene manipulation of Corynebacterium glutamicum KFCC-11074, and a process of producing L-glutamic acid using the mutant strains. The mutant strains are capable of producing L-Glutamic acid at high yield.
