本研究采用解淀粉芽孢杆菌发酵红小豆(Vigna umbellata),并评价了发酵红小豆的理化特性和生物活性。以纤溶酶活性为指标优化了发酵条件,在最适发酵条件下,纤溶酶活性最高达78.0 FU∙g-1(4890 IU∙g-1,纤维蛋白平板法)。发酵红小豆中多肽含量(2.1~10.9 g∙100 g-1)、总酚含量(116.7~388.5 mg没食子酸∙100 g-1)、总黄酮含量(235.5~354.3 mg芦丁∙100 g-1)、花青素含量(20.1~47.1 mg∙100 g-1)和超氧化物歧化酶活性(55.3~263.6 U∙g-1)显著增加。红小豆经发酵后的2,2-二苯基-1-苦肼基(DPPH)和2,2-联氮双(3-乙基苯并噻唑啉-6-磺酸)二铵盐(ABTS)自由基清除活性和铁离子还原抗氧化能力(FRAP)较未发酵的红小豆提高1.9~4.8倍。此外,发酵红小豆的二肽基肽酶Ⅳ(DPP-Ⅳ)抑制活性、α-葡萄糖苷酶抑制活性和抗凝血活性显著提高。解淀粉芽孢杆菌发酵红小豆具有多种功能活性,对开发预防血栓性疾病的功能食品具有重要意义。

A new type of traction drive system consisting of solid-state traction transformer (SSTT), inverter unit, auxiliary inverter, traction motor and other key components is built in order to suit the demand of developing the next-generation electric traction system which will be efficient and lightweight, with high power density. For the purpose of reducing system volume and weight and improving efficiency and grid-side power quality, an efficient SSTT optimized topology combining high-voltage cascaded rectifiers with high-power high-frequency LLC resonant converter is proposed. On this basis, an integrated control strategy built upon synchronous rotating reference frame is presented to achieve unified control over fundamental active, reactive and harmonic components. The carrier-interleaving phase shift modulation strategy is proposed to improve the harmonic performance of cascaded rectifiers. In view of the secondary pulsating existing in a single-phase system, the mathematical model of secondary power transfer is built, and the mechanism of pulsating voltage resulting in beat frequency of LLC resonant converter is revealed, so as to design optimum matching of system parameters. Simulation and experimental results have verified that the traction system and control scheme mentioned in this paper are reasonable and superior and that they meet the future application requirements for rail transit.
