    • The present invention comprises the discovery and development of an effective cryoprotectant composition, without containing skim milk or any other animal-derived compounds, to achieve long-term stability of freeze-dried lactic acid bacteria (LAB), at different temperatures, whereby the retention of viability of the freeze-dried LAB after 6 months of storage, preferably after 9 months of storage, more preferably after 12 months of storage is more than 50%. The invention is in the field of producing freeze dried bacteria, in particular Lactic acid bacteria. More in particular, the invention relates to the use of a novel combination of cryoprotectants for increasing the viability of bacteria after freeze drying, improving the texture of the lyofilized cake for easy grinding and improving the long term stability of the freeze dried bacteria at different temperature conditions. The invention further relates to such freeze dried bacteria for use in food industry or in human or animal health applications. More in particular, the invention relates to the increased viability and long-term storage of recombinant bacteria capable of expressing heterologous proteins or peptides and administered to humans or animals for therapeutic or vaccination purposes.
    • 本发明包括在不同温度下发现和开发有效的冷冻保护剂组合物,不含脱脂乳或任何其它动物衍生化合物以达到冷冻干燥的乳酸菌(LAB)的长期稳定性,从而保留 冷冻干燥的LAB在储存6个月后的存活率,优选储存9个月后,更优选储存12个月后超过50%。 本发明涉及生产冷冻干燥细菌,特别是乳酸菌的领域。 更具体地,本发明涉及使用冷冻保护剂的新型组合来增加冷冻干燥后细菌的存活力,改善裂解饼的质地以便于研磨,并提高冷冻干燥细菌在不同温度下的长期稳定性 条件。 本发明还涉及用于食品工业或人或动物健康应用的这种冷冻干燥细菌。 更具体地,本发明涉及能够表达异源蛋白质或肽并且施用于人或动物用于治疗或疫苗接种目的的重组细菌的增加的活力和长期储存。

    • An expression system for producing an enzyme, and a method for preparing same, are disclosed. The system includes a promoter nucleotide sequence, a nucleotide sequence coding for a secretion signal, a nucleotide sequence coding for a mature enzyme and a terminator nucleotide sequence. The expression system is particularly useful for producing a Pseudomonas lipase. Said expression system may be inserted into a vector. A Pseudomonas wisconsinensis strain transformed by the expression vector is used as the host strain. The expression system may also include a nucleotide sequence coding the Pseudomonas wisconsinensis lipase modulator and/or a nucleotide sequence coding for the GPW protein included in the Pseudomonas wisconsinensis lipase operon. The Pseudomonas wisconsinensis lipase modulator that is involved in effective lipase expression and aids the formation of an active lipase is also disclosed. Furthermore, the GPW protein that appears also to be involved in effective lipase expression is disclosed. The resulting lipase may be used in detergent compositions.
    • 公开了一种用于生产酶的表达系统及其制备方法。 该系统包括启动子核苷酸序列,编码分泌信号的核苷酸序列,编码成熟酶的核苷酸序列和终止子核苷酸序列。 表达系统对于产生假单胞菌脂肪酶特别有用。 所述表达系统可以被插入向量中。 将由表达载体转化的威斯康星假单胞菌菌株用作宿主菌株。 表达系统还可以包括编码威斯康星州假单胞菌脂肪酶调节剂的核苷酸序列和/或编码威斯康星州假单胞菌脂肪酶操纵子中包含的GPW蛋白的核苷酸序列。 还公开了参与有效脂肪酶表达并有助于形成活性脂肪酶的假单胞菌威斯康星州脂肪酶调节剂。 此外,还公开了也参与有效脂肪酶表达的GPW蛋白质。 所得脂肪酶可用于洗涤剂组合物中。
