This book was released on 2022-02-24 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk occupies a strategic place in the daily diet of man, because of its noble components and its richness in vitamins and minerals, especially in dietary calcium. (RAHLI, 2015) Raw milk because of its richness in nutrients (proteins, fats, carbohydrates, vitamins... etc.), is a favourable environment for the development of germs. When taken in good conditions, raw milk contains few germs (103 sprouts per ml).These are saprophytic germs and among them are Lactobacillus, Streptococcus and Leuconostoc. (MENAD, 2017). It also has an antimicrobial effect against pathogenic bacteria, among which are Listeria monocytogenes, Escherichia coli, Staphylococcus aureus and Salmonella typhimurium. This antimicrobial activity is attributed to the presence of lactic acid bacteria that produce antimicrobial substances such as bacteriocin.

This book was released on 2016-06-24 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial polysaccharides represent an attractive alternative to those from plants or macro algae. They can be produced from renewable sources including lignocellulosic waste streams. Their production does not depend on geographical constraints and/or seasonal limitations. Additionally the manipulation of biosynthetic pathways to enhance productivity or to influence the chemical polysaccharide composition is comparatively easy in bacteria. Microbial exopolysaccharides represents a valuable resource of biogenic and biodegradable polymers, suitable to replace petro based polymers in various technical applications. Furthermore, biocompatible exopolysaccharides are very attractive in medical applications, such as drug delivery systems, use as vaccines or nanoparticles. This research topic will depict the status quo, as well as the future needs in the field of EPS and biofilm research. Starting from the unexplored diversity of microbial polysaccharide producers to production processes and possibilities for modifications, to enhance the already high number of functionalities based on the chemical structures. An overview of the recent and future applications will be given, and the necessity in unravelling the biosynthesis of microbial exopolysaccharide producers is depicted, highlighting the future trend of tailor made polymers. Constraints in structure analysis of these highly complex biogenic polymers are described and different approaches to solve the restrictions in imaging and NMR analysis will be given. Therefore; this research topic comprises the whole process from genes to applications.

Download or read book Bacteriocins of Lactic Acid Bacteria written by Luc De Vuyst and published by Springer. This book was released on 2012-12-06 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: As antibacterial compounds, bacteriocins have always lived in the shadow of those medically important, efficient and often broad-spectrum low-molecular mass antimicrobials, well known even to laypeople as antibiotics. This is despite the fact that bacteriocins were discovered as early as 1928, a year before the penicillin saga started. Bacteriocins are antimicrobial proteins or oligopeptides, displaying a much narrower activity spectrum than antibiotics; they are mainly active against bacterial strains taxonomically closely related to the producer strain, which is usually immune to its own bacteriocin. They form a heterogenous group with regard to the taxonomy of the producing bacterial strains, mode of action, inhibitory spectrum and protein structure and composition. Best known are the colicins and microcins produced by Enterobacteriaceae. Many other Gram-negative as well as Gram-positive bacteria have now been found to produce bacteriocins. In the last decade renewed interest has focused on the bacteriocins from lactic acid bacteria, which are industrially and agriculturally very important. Some of these compounds are even active against food spoilage bacteria and endospore formers and also against certain clinically important (food-borne) pathogens. Recently, bacteriocins from lactic acid bacteria have been studied intensively from every possible scientific angle: microbiology, biochemistry, molecular biology and food technology. Intelligent screening is going on to find novel compounds with unexpected properties, just as has happened (and is still happening) with the antibiotics. Knowledge, especially about bacteriocins from lactic acid bacteria, is accumulating very rapidly.

Download or read book Biofilms in the Food and Beverage Industries written by P. Fratamico and published by CRC Press. This book was released on 2009-10-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilms in the Food and Beverage Industries reviews the formation of biofilms and the best practices for their control. When bacteria attach to and colonize the surfaces of food processing equipment and food products themselves, there is a risk that biofilms may form. Human pathogens in biofilms can be harder to remove than free microorganisms and may therefore pose a more significant food safety risk. Part one considers fundamental aspects such as molecular mechanisms of biofilm formation by food-associated bacteria and methods for biofilm imaging, quantification and monitoring. Part two then reviews biofilm formation by different microorganisms. Chapters in Part three focus on significant issues related to biofilm prevention and removal. Contributions on biofilms in particular food industry sectors, such as dairy and red meat processing and fresh produce, complete the collection. With its distinguished editors and international team of contributors, Biofilms in the Food and Beverage Industries is a beneficial reference for microbiologists and those in industry responsible for food safety.

Download or read book Human Behavior and Environmental Sustainability written by Charles Vlek and published by Wiley-Blackwell. This book was released on 2007-03-20 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental sustainability is a necessity for all countries worldwide, and it is strongly related to human quality of life. Given that sustainability problems largely result from human-environment interactions, social and behavioral research is developing as a necessary complement to natural-science and technological studies of environmental problems. To demonstrate this, the various authors address key theoretical, methodological and policy-making questions about the behavioral dimensions of environmental sustainability. Successively considered are the appreciation of environmental risk, citizens’ annoyance from environmental noise, the evaluation of urban environmental quality, the restorative significance of nature experiences, fundamental behavioral processes and environmental motivations, and unsustainable-behavior change and the roles of technology therein. The usefulness of multidisciplinary research is emphasized. Finally explicated is psychology’s drive and potential for analyzing and supporting environmental sustainability as a long-term human social and economic interest.
