Although malodour formation on textiles and in washing machines has been reported to be a very relevant problem in domestic laundry, the processes leading to bad odours have not been studied intensively. In particular, the smell often described as "wet-and-dirty-dustcloth-like malodour" had not been reproduced previously. We developed a lab model based on a bacterial mixture of , , and , which can produce this odour type and which might allow the detailed investigation of this problem and the development of counteractions. The model uses bacterial strains that have been isolated from malodourous textiles. We could also show that the three volatile compounds dimethyl disulfide, dimethyl trisulfide, and indole contribute considerably to the "wet-fabric-like" malodour. These substances were not only found to be formed in the malodour model but have already been identified in the literature as relevant malodourous substances.
尽管据报道，纺织品和洗衣机中产生恶臭是家庭洗衣中一个非常严重的问题，但导致产生难闻气味的过程尚未得到深入研究。特别是，那种常被描述为“类似湿脏抹布的恶臭”的气味此前尚未被重现出来。我们基于嗜麦芽窄食单胞菌、解淀粉芽孢杆菌和阴沟肠杆菌的混合菌群开发了一种实验室模型，该模型能够产生这种气味类型，并且可能有助于对这一问题进行详细研究以及制定应对措施。该模型使用的是从有臭味的纺织品中分离出来的细菌菌株。我们还发现，二甲基二硫醚、二甲基三硫醚和吲哚这三种挥发性化合物对“类似湿织物的”恶臭有很大影响。这些物质不仅在恶臭模型中被发现会形成，而且在文献中已被确认为相关的恶臭物质。
