Abstract: A method for producing microbial intracellular products, and more particularly a method of producing microbial intracellular products from volatile fatty acids derived from organic waste is provided. The method of producing microbial intracellular products from volatile fatty acids in a multi-stage continuous high-cell-density culture bioreactor system includes the steps of: (a) culturing microorganisms in a bioreactor for microbial growth, thereby growing the microorganisms; (b) culturing the grown microorganisms of step (a) in a bioreactor for production of microbial intracellular products, which includes a medium containing volatile fatty acids, thereby producing microbial intracellular products; and (c) recovering the intracellular microbial products from the culture medium of the bioreactor for production of microbial intracellular products.

Abstract: The present invention relates to a method for concentrating law titer fermentation broth, and more particularly to a method for concentrating a fermentation broth using forward osmosis. The method comprises: introducing the fermentation broth and an osmolyte into a feed chamber and a draw chamber, respectively, which are included in a concentration system and are divided from each other by a forward osmosis membrane, and subjecting the introduced fermentation broth to forward osmosis, thereby concentrating the fermentation broth in the feed chamber. The method can maximize the concentration of the low titer fermentation broth while minimizing energy consumption and operating cost, and thus can contribute to the industrialization of new technology.

Abstract: A reflective liquid crystal display device includes: first and second substrates spaced apart and facing each other; a twisted nematic liquid crystal layer sandwiched between the two substrates, the liquid crystal layer having a twist angle and birefringence property &Dgr;n and having a thickness d; a retardation film disposed on the first substrate and opposite to the liquid crystal layer, the film converting a first linearly polarized light from above to a first circularly polarized light and converting a second circularly polarized light reflected from below to a second linearly polarized light; a linear polarizer disposed on the retardation film and opposite to the liquid crystal layer and converting the incident light to the first linearly polarized light; and a reflector disposed between the liquid crystal layer and the second substrate and reflecting light passed through the liquid crystal layer. A most desirable range for the twist angle is between above 65° and 75° or 75° and 85° and a most desirable range of a product d&Dgr;n is between about 0.20 &mgr;m and 0.28 &mgr;m or 0.18 &mgr;m and 0.26 &mgr;m. By the invention, light reflectance, contrast ratio and yield can be enhanced.
