The origin of the competitive exclusion (CE) concept in controlling a Salmonella infantis outbreak in poultry in 1971 and the subsequent development of a commercial treatment product are described. The possible role of CE in salmonella control, current status of the concept and theories relating to the bacteria involved and mechanisms of protection are reviewed. Some observations are made on the need for methodological development and possibilities for extending the scope of CE to other pathogens and types of domestic animal. 相似文献

The origins of cheesemaking and the gradual growth of the cheese industry in Britain are reviewed. The factors responsible for the evolution of our present varieties are discussed, and the contributions of the leading 19th century cheesemakers. teachers, and dairy chemists are described. The reasons for the decline of farmhouse cheesemaking and the growth of the cheese factory or creamery are also discussed.
In spite of the progress made in dairy chemistry and microbiology. cheesemaking still remains largely a craft, although specialized aspects can now be controlled scientifically. Not until microorganisms can be eliminated or their behaviour completely controlled will cheesemaking become a true technology or applied science. 相似文献

The influence of the mind on the body and the body's influence on the mind have far reaching implications for human health and well-being in modern society. One of the most salient present-day examples of this interaction is the complex relationship between emotional state and skin health, which appears to be positively correlated. Because odorants have been demonstrated to improve mood and increase relaxation, Aromachology can assist in the maintenance of good skin health, and can be an important part of skin-care practices. Through both the natural qualities of odorants and through odor-induced stress-reduction, the sense of smell can enhance skin appearance and health, which leads to a sense of well-being and better quality of life. 相似文献

21世纪制浆厂的建设将与之前浆厂有很大不同,因为来自能源利用最大化、提高产品质量、降低环境影响和优化资产和操作成本等多方面的压力使21世纪制浆厂在动土建设前就需要考虑各方面因素,以使工艺生产和周围环境满足上述要求.现阶段,大多数的新建制浆厂都选择在亚洲和南美地区,因为这两个地区适合速生材原材料的生产和其他的一些优势,如降低投入成本且资本回收周期短. 相似文献

<正> 公元2001年11月10日,中国加入WTO。我国乳品工业,尤其是婴幼儿奶粉生产厂家将面临新的机遇与挑战。加入WTO后,首先是要减让关税。目前,我国乳制品进口关税平均为26%。到2004年可能降到10~15%,生产辅助原料的进口关税也将大幅度下降。这表明,我国婴幼儿奶粉市场将受到一定的冲击。 相似文献
