The influence of nutrients in wastewater from dairy lagoons on the survival of Escherichia coli O157:H7 was monitored. Initially, the survival of E. coli O157:H7 in wastewater from which the competing native organisms had been removed by filter sterilization or autoclaving was compared with that in wastewater from which competing organisms had not been removed. Numbers of E. coli O157:H7 or E. ...

Milk proteins play a range of roles which make dairy products and products containing dairy components are valuable. Theses include nutrition, physical functionality and breakdown under controlled condition to produce nutritional, functional or flavour full products. This article reviews the structure of whey protein concequence for dairy industry. [Journal of American Science. 2010;6(11):79-84...

Widespread speculation about the possible role of MAP in Crohn’s disease in humans has led to concern within the dairy industry, particularly since some studies have shown that the organism can survive pasteurization. A national control strategy would promote and protect New Zealand dairy export sales and match efforts by other major dairy producers such as the US, Australia and some EU countries.

Representatives of the genus Bacillus are common milk contaminants that cause spoilage and flavor alterations of dairy products. Bacillus sp. FMQ74 was isolated from raw milk on a Danish dairy farm. To elucidate the genomic basis of this strain's survival in the dairy industry, a high-quality draft genome was produced.

As advances in dairy cattle nutrition research are now becoming available to the dairy industry, it is sometimes difficult to understand how these differ ent advances and improvements in our understanding of dairy nutrition with the different approaches taken by different companies and their associated “jargon”. This brochure is meant as a general overview of the different ration balancing syst...

The objective of this paper is simultaneous of aerobic and anaerobic process for phosphorus removal from a dairy wastewater. The system consists of a granular sequencing batch reactor (SBR) working under alternating aerobic/anaerobic conditions. In order to analyze the process, four significant variables viz. MLSS, COD/N ratio, aeration time and cycling time and four dependent parameters as the...

Wastewater from dairy industries, characterized by its high COD content and relative high COD/TKN ratio, requires post-treatment after anaerobic treatment to complete the removal of organic matter and nutrients. Due to its simplicity, robustness and low maintenance costs, sequencing batch reactors (SBR) result in an attractive system, especially in case of small dairy industries in order to com...

The dairy industry in the developed world has undergone profound changes over recent decades. In this paper, we present an overview of some of the most important recent changes in the dairy industry that affect health and welfare of dairy cows, as well as the science associated with these changes. Additionally, knowledge gaps are identified where research is needed to guide the dairy industry t...

Membrane Bioreactors (MBRs) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. They have proven quite effective in removing organic and inorganic contaminants as well as biological entities from wastewater. Advantages of the MBR include good control of biological activity, high quality effluent free of bacteria and pathogens, smaller...
