Abstract:
The present invention relates to a mutant Nannochloropsis oculata strain (KCTC18241P) with an increased intercellular lipid content and a method for manufacturing lipid using the same. According to the present invention, provided is a mutant Nannochloropsis oculata strain with high growth rate and an increased lipid content. Moreover, the mutant Nannochloropsis oculata strain of the present invention has a low pigment content compared with wild Nannochloropsis oculata to simplify a biodiesel separation process.
Abstract:
PURPOSE: An immunity improving composition is provided to improve the expression level of NO and cytokine of macrophagocyte, and to use the composition as health functional food and a pharmaceutical composition. CONSTITUTION: Immunity improving health functional food contains neo glycoprotein generated from the maillard reaction of galactomannan and lysozyme as an active ingredient. The galactomannan contains mannose and galactose in a ratio of 4:1, and the molecular weight of the galactomannan is 300-330 kDa. The molecular weight of the lysozyme is 13-15 kDa. The maillard reaction is conducted by making galactomannan react with the lysozyme in a weight ratio of 10:1 to 1:1.
Abstract:
PURPOSE: A method for preparing a rice bran-derived glycoprotein fraction and a composition containing the fraction for enhancing immunity are provided to promote NO and TNF-alpha generation. CONSTITUTION: A rice bran-derived glycoprotein fraction comprises: a step of defatting rice bran; a step of mixing the rice bran in a buffer solution of pH 7.0-8.0; a step of centrifuging the mixture to obtain supernatant; a step of performing dialysis of the supernatant using dialysis semipermeable membrane; a step of adding salt to precipitate glycoproteins; a step of dissolving the precipitate in a buffer solution of pH 7.0-8.0 and performing dialysis with the dialysis semipermeable membrane; and a step of freeze-drying the dissolved precipitate. A composition for enhancing immunity contains the glycoprotein fraction as an active ingredient. A pharmaceutical composition for preventing or treating cold, atopy, chronic fatigue, or cancer contains the fraction as an active ingredient.
