Abstract: PURPOSE:To obtain l-malic acid in high yield, by subjecting a culture solution of a fungus belonging to the genus Alcaligenes, capable of assimilating maleic acid, etc. to contact reaction with maleic acid or fumaric acid. CONSTITUTION:A culture solution of a fungus [preferably strain of Alcaligenes sp. T125(FERM-P 7323) or T501(FERM-P 7324)] belonging to the genys Alcaligenes, capable of assimilating maleic acid or a treated material of it is subjected to contact reaction with maleic acid or fumaric acid preferably at 6-9pH at 25-40 deg.C, to give l-malic acid enzymatically.

Abstract: PURPOSE:To obtain the titled reagent which does not cause nonspecific flocculation and adsorption by using fine particles of a crosslinked polymer having specific repetitive units as a particulate carrier for fixing immune activity. CONSTITUTION:Fine particles of a crosslinked polymer having the repetitive units shown by the formula (R is H, methyl) and 0.03-10mu average particle sizes is used as a particulate carrier. The above-mentioned polymer is formed by (co)polymerizing, for example, 2,3-oxypropyl acrylate and/or methacrylate (the amount of using other copolymerizable monomers is about
