    • The invention concerns bacteria having byle salt hydrolysis activity and optionally and preferably also bile salt polymerisation activity. Food products comprising such bacteria have been found to be capable to reduce the blood cholesterol level in the human blood. The effect is obtained by interference with the cholesterol and/or bile salt metabolism and is based on BSH activity of the bacteria. Food products which, on the basis of their normal daily intake provide a daily-BSH-intake of 0.3 micro-mol/min/kg bodyweight, are preferred, and even more preferred are food products providing at least a daily-BSH-intake of 0.6 micro-mol/min/kg bodyweight. In a further preferred embodiment a BSH activity of at least 0.8 micro-mol/min/1e10 cfu is obtained by the common, daily intake of food products comprising the bacteria. Further preferred are food products comprising fat, wherein at least 40% of the fat are poly unsaturated fatty acids.
    • 本发明涉及具有副盐水解活性和任选且优选也是胆盐聚合活性的细菌。 已经发现包含这种细菌的食品能够降低人血液中的血液胆固醇水平。 通过干扰胆固醇和/或胆汁盐代谢而获得的效果是基于细菌的BSH活性。 以每日正常摄入量为基础的食品,优选为0.3微摩尔/分/公斤体重的日常BSH摄入量,更优选的是至少提供每日BSH摄入量的BSH摄入量 0.6微mol / min / kg体重。 在另一个优选的实施方案中,通过每天摄入含有细菌的食品,获得至少0.8微摩尔/分钟/ 1e10cfu的BSH活性。 进一步优选的是包含脂肪的食品,其中至少40%的脂肪是多不饱和脂肪酸。

    • Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Protease variants are provided that contain substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more negative or less positive compared to a precursor protease and thus the protease variant is more effective in a low detergent concentration system than a precursor protease. Also provided are protease variants containing substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more positive or less negative compared to a precursor protease and thus the protease variant is more effective in a high detergent concentration system than a precursor protease. Protease variants are provided that contain substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more negative or less positive compared to a precursor protease and thus the protease variant is more effective in a medium detergent concentration system than a precursor protease. Also provided are protease variants containing substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more positive or less negative compared to a precursor protease and thus the protease variant is more effective in a medium detergent concentration system than a precursor protease. Further provided is a method of producing a protease variant that is more effective in a low detergent concentration system, medium detergent concentration system and high detergent concentration system than a precursor protease.
