    • The present invention provides a novel lipase with a molecular weight of about 32 kDa, which is produced by a strain belonging to the genus Tetrasphaera, as well as a gene encoding the same. This lipase has the ability to recognize a medium-chain fatty acid as a substrate. The present invention also provides a novel lipase with a molecular weight of about 40 kDa, which is produced by a strain belonging to the genus Tetrasphaera and has the ability to recognize both a medium-chain fatty acid and a long-chain fatty acid as substrates, as well as a polynucleotide encoding the same. The present invention further provides Tetrasphaera sp. strain NITE P-154. The lipase of the present invention can be used as an immobilized enzyme and is useful in fields such as production of digestants and/or flavorings, production of clinical laboratory reagents, detergent enzymes and/or fats, as well as production of optically active intermediates for agricultural chemicals and pharmaceutical preparations.

    • The present invention provides a novel ascorbic acid derivative as a provitamin C with improved stability in the body and prolonged life in the body compared to conventionally known 2-O-(β-D-glucopyranosyl)ascorbic acid. The composition comprising the novel compound 2-O- (β-D-glucopyranosyl)ascorbic acid has been extracted from plants such as from Ningxia Lycium barbarum L. and/or Lycium chinense Mill. The compositions comprising 2-O-(βD-glucopyranosyl) ascorbic acid may be enzymatically synthesized using β-D-glucosyltransferase. Pure 2-O-(β-D-glucopyranosyl)ascorbic acid may be produced from such compositions. Alternatively, 2-O-(β-D-glucopyranosyl)ascorbic acid may be produced by chemical synthesis. The 2-O-(β-D-glucopyranosyl)ascorbic acid results in higher stability and a prolonged life of vitamin C when ingested in the body compared to the corresponding α-D-glucopyranosyl derivative, and is therefore highly suitable as a provitamin C to be used in cosmetics and foods.
    • 本发明提供了一种新颖的抗坏血酸衍生物作为前维生素C,与常规已知的2-O-(β-葡萄糖-D-吡喃葡萄糖基)抗坏血酸相比,体内的稳定性和体内寿命延长。 含有新化合物2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸的组合物已经从宁夏枸杞子和/或枸杞子等植物中提取出来。 包含2-O-(β-葡萄糖吡喃糖基)抗坏血酸的组合物可以使用β-葡糖基转移酶酶促合成。 可以从这样的组合物制备纯2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸。 或者,可通过化学合成制备2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸。 与对应的α-D-吡喃葡萄糖基衍生物相比,2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸在身体摄取时导致更高的稳定性和更长的维生素C的使用寿命,因此非常适合作为维生素 C用于化妆品和食品。
