Book Description :

The Bifidobacteria and Related Organisms: Biology, Taxonomy, Applications brings together authoritative reviews on all aspects of Bifidobacteria and related genera. Their place within the Phylum Actinobacteria is discussed first, and this is followed by descriptions of the genera Bifidobacterium, Alloscardovia, Aeriscardovia, Bombiscardovia, Gardnerella, Metascardovia, Parascardovia and Scardovia and the currently accredited species within those genera. The increased availability of genome sequences and molecular tools for studying bifidobacteria provides important information about their taxonomy, physiology and interactions with their host. Also considerations about common bifidobacterial core maintenance during the mutual coevolution of a host and its intestinal microbes could be relevant for health claims for the ability of symbiotic gut bacteria to provide health benefits to their host, and for evaluating such claims in scientifically valid experiments. Chemotaxonomy is important to our understanding of these genera and so is considered along with physiological and biochemical aspects before proceeding to examine clinical and other practical aspects. The ability to maintain pure cultures and to grow cells in industrial quantities when required for applications requires that the cells’ environmental and nutritional needs are well understood. Some species are important clinically and as animal digestive tract synbionts—and even play a part in honey production—so these matters are considered along with milk oligosaccharides’ roles in gut flora development in neonates. Presents information on all bacteria in this group in one place Provides applications and technological considerations placed alongside more academic matters such as nomenclature and phylogeny Includes basic information on the beneficial role of bifidobacteria in the human gut, with particular importance for infants Provides information on genomic and gene modification technologies

Book Description :

The lactic acid bacteria (LAB) are a group of relatedmicro-organisms that are enormously important in the food and beverage industries. Generally regarded as safe for humanconsumption (and, in the case of probiotics, positively beneficialto human health), the LAB have been used for centuries, andcontinue to be used worldwide on an industrial scale, in foodfermentation processes, including yoghurt, cheeses, fermented meatsand vegetables, where they ferment carbohydrates in the foods,producing lactic acid and creating an environment unsuitable forfood spoilage organisms and pathogens to survive. The shelf life ofthe product is thereby extended, but of course these foods are alsoenjoyed around the world for their organoleptic qualities. They are also important to the brewing and winemaking industries,where they are often undesirable intruders but can in specificcases have desirable benefits. The LAB are also used in producingsilage and other agricultural animal feeds. Clinically, theycan improve the digestive health of young animals, and also havehuman medical applications. This book provides a much-needed and comprehensive account ofthe current knowledge of the lactic acid bacteria, covering thetaxonomy and relevant biochemistry, physiology and molecularbiology of these scientifically and commercially importantmicro-organisms. It is directed to bringing together the currentunderstanding concerning the organisms’ remarkable diversitywithin a seemingly rather constrained compass. The genera now identified as proper members of the LAB aretreated in dedicated chapters, and the species properly recognized as members of each genus arelisted with detailed descriptions of their principalcharacteristics. Each genus and species is described using astandardized format, and the relative importance of each species infood, agricultural and medical applications is assessed. Inaddition, certain other bacterial groups (such asBifidobacterium) often associated with the LAB are givenin-depth coverage. The book will also contribute to a betterunderstanding and appreciation of the role of LAB in the variousecological ecosystems and niches that they occupy. Insummary, this volume gathers together information designed toenable the organisms’ fullest industrial, nutritional andmedical applications. Lactic Acid Bacteria: Biodiversity and Taxonomy is anessential reference for research scientists, biochemists andmicrobiologists working in the food and fermentation industries andin research institutions. Advanced students of food science andtechnology will also find it an indispensable guide to thesubject.

Book Description :

The study had three principal aims related to pediococci and bifidobacteria and their enumeration, genomic characterisation and applicability as probiotics. Two selective edia based on mMRS with mupirocin or mixture of ampicillin, novobiocin, and vancomycin were developed for bifidobacteria and pediococci, respectively. Both media were applied to a range of cultures, powder-based products and porcine caecal samples. A detailed examination of RAPD PCR and PFGE found both methods effectively discriminated Bifidobacterium strains and Pediococcus strains and species. A detailed description of the bifidobacteria population associated with a porcine caecum was described using PFGE. The same Bifidobacterium strains were found to be associated with the epithelium and lumen contents. This implied that a dynamic interaction between adhering and non-adhering cells exists and that, for the caecum at least, bacterial growth can occur within the GIT lumen. In addition, based on subtle differences in PFGE patterns evidence for genomic plasticity was observed and this was considered to be a possible mechanism underlying long-term colonisation. Furthermore, based on a number of approaches that included 16S rDNA sequencing three known Bifidobacterium species were identified that included B. minimum a species that had only previously been isolated from sewage. Moreover, a novel species, Bifidobacterium pyschraerophilum, and a novel genus and species, Aeriscardovia aeriphila were identified and distinguished by their marked resistance to oxygen. With regards to the safety of pediococci and their use in feed, food and silage, erythromycin resistance in a P. acidilactic strain was found to be plasmid encoded. With regards to developing food-grade powders containing high levels of viable and stable bifidobacteria the intrinsic tolerance of Bifidobacterium species to heat and oxygen was established. A group of closely related species with a tolerance to both parameters were identified. Following spray drying at laboratory-scale, heat and oxygen tolerant species had high initial survival and good viability at refrigerated temperatures in skim-milk powders. However, oxygen tolerance alone did not correlate with high initial survival or good storage viability. Viability during storage at ambient temperatures was significantly reduced for all species but was greatly improved when bifidobacteria were dried using a pilot-scale fluidised-bed spray dryer. Ice cream was manufactured using bifidobacteria enriched skim-milk spray-dried powder.

Book Description :

The human intestine is home of an almost inconceivable large number of microorganisms. The human gut microbiota can therefore be pictured as an organ placed within a host organism. The human gut microbiome, which in total may contain >100 times the number of genes present in our genome, endows us with functional features that we did not have to evolve ourselves. It is recognized that intestinal microbiota plays an important role in human health and disease. In fact, gut bacteria other than metabolize dietary components, may play complex roles such as modulation of the immune system and in reduction of gut infections. Variations in the presence and/or abundance of certain components of the intestinal microbiota have repeatedly been observed in patients that suffer from atopic diseases, inflammatory bowel disease, Crohn disease, ulcerative colitis, infectious colitis, colon cancer and diabetes. In this context, bifidobacteria represent one of the most common bacterial members of the human gut microbiota. Bifidobacteria are anaerobic, Gram-positive, irregular or branched rod-shaped bacteria that are commonly found in the gastro-intestinal tracts (GIT) of humans, especially during the first stages of life and most animal and insects. Bifidobacterial fluctuations seem directly associated with health effects and for these reasons they are being exploited as health-promoting or probiotic bacteria. However, despite the extensive commercial exploitation of bifidobacteria as probiotic bacteria, little is known about their impact or dependency on other members of the human gut microbiota or on their host. Genome analyses have highlighted the existence of gene repertoires encoding products that are responsible for the adaptation of bifidobacteria to the human intestine and intense research efforts at international level are ongoing to understand the molecular details of these interactions. Specifically, the molecular interactions that are presumed to exist between bifidobacteria and the human host, as well as interactions between different residents of intestinal microbiota are the main topic of bifidobacterial research communities.

Book Description :

RNA is a chemical found in the nucleus and cytoplasm of cells. RNA plays an important role in protein synthesis and other chemical activities of the cell. The structure of RNA is similar to that of DNA, although RNA is single stranded whereas DNA has a characteristic "double helix". Genetic information is stored by DNA in the nucleus of cells, and RNA carries that information to other parts of the cell where it is converted into protein. Three types of RNA are; mRNA (messenger RNA, which contains the specific sequence of nucleotides necessary to dictate amino acid sequence in proteins), tRNA (transfer RNA, which serves as the "adapter" to position the appropriate amino acid next to a growing polypeptide chain during protein synthesis), and rRNA (ribosomal RNA, which is the RNA component of ribosomes). This book presents state-of-the-research from throughout the world.

Book Description :

It is hardly controversial to propose that an environment has an effect on the residents of that environment. The interaction between hosts and their associated microbes spans many forms of life, from plant roots to the human gut. It is in understanding the mechanism of this interaction that challenges lie, and it is this that is the focus of this dissertation. The first chapter is a review of current understanding of the relationship between the genus Bifidobacterium and the components of human milk that influence its symbiosis with the infant gut. The review focuses primarily on human milk oligosaccharides (HMO), complex sugars that are abundant in human milk and are left undigested by the infant, arriving intact into the colon. The second chapter is an in-depth analysis of a single species of Bifidobacterium, B. pseudocatenulatum. This species has been encountered frequently in the human gut (both infant and adult), but has rarely been the focus of direct study. That chapter explores the genetic diversity of the species, as well as its functional diversity in an HMO context. The third chapter describes the validation of a tool used to differentiate between bifidobacteria in a complex community, something that is necessary when attempting to use probiotic products with specific outcomes in mind. The final chapter, a brief description of work that is not yet complete, shows that components in milk other than HMOs, namely fatty acids, also have an effect on the behavior of bifidobacteria, namely B. longum subsp. infantis. Those last two chapters were projects to which I contributed, but were led by other researchers, and are preceded by an explanation of my contribution. The overall conclusion, permeating throughout this dissertation, is that Bifidobacterium species possess characteristics that clearly make them adapted to the human, and particularly infant, gut environment.
