Abstract: A process for the production of animal feed additives from fermentation broth containing L-lysine is disclosed. The process does not require filtering of biomass in order to remove the biomass and produces granulated lysine of controllable lysine content with a high bulk density, low viscosity, and a low hygroscopic property which does not require the addition of an anti-absorptive substance. In this process, a lysine fermentation broth produced after slant culture, flask culture, seed process, and cultivation process is concentrated to a solid content of about 44˜52%. A product with low hygroscopicity, high bulk density, and the intended amount of contents is produced after being mixed with substances for controlling the amount of contents and granulated by coating the surface of the seeds. This process enables a production of animal feed additives having a lysine-HCl content of at least 65%, a water content of at most 3%, and a bulk density of 670±50 kg/m3.

Abstract: A sterilizer, which is not large, but includes a hermetic container capable of defining a sealed space therein without being closed by a locking device from the outside, is disclosed. The sterilizer includes a hermetic container, which defines therein a steam chamber for conducting the heat sterilization of objects. The hermetic container includes a steam supply unit for supplying hot steam to the steam chamber, and an opening/closing unit for closing the steam chamber. The opening/closing unit includes an opening for passing the objects and a door for closing the opening from the inside of the chamber. The door is moved to come into contact with the opening from the inside, and the steam pressure inside the steam chamber is increased by the pressurized steam from the steam supply unit, so that the door can come into close contact with the opening, thus hermetically sealing the steam chamber.

Abstract: A method for producing L-threonine using a microorganism is provided. In the method, additional one or more copies of each of the phosphoenolpyruvate carboxylase (ppc) gene and the threonine operon are integrated into a particular site of the chromosomal DNA of a microorganism, while its inherent ppc gene and threonine operon remain. Accordingly, two or more ppc genes and threonine operons are included in the chromosomal DNA of the microorganism to thereby enhance the expression of the ppc gene encoding an enzyme to convert phosphoenolpyruvate to a threonine biosynthesis precursor, oxaloacetete, and the genes encoding enzymes involved in the synthetic pathway of threonine from oxaloacetate, including thrA (aspartokinasel-homoserine dehydrogenase), thrB (homoserine kinase), and thrC (threonine synthase), thereby markedly increasing L-threonine productivity.
