Book excerpt: Fresh sprouts have been responsible for 30 foodborne illness outbreaks and 1800 cases since 1996 in the United States. Use of chemical sanitizers prior to the sprouting process has been attempted in many studies to decontaminate or control the growth of pathogens. In 1999, FDA issued a guidance to reduce microbial food safety hazards for sprouted seeds. However, even after FDA's guidance, continuous outbreaks have still been a serious concern for consumers. In an attempt to control the growth of foodborne pathogens on sprouts using protective cultures, lactic acid bacteria (LAB) were isolated from fermented sprouts. Many of the LAB isolates were found to produce bacteriocins, which are ribosomally synthesized antimicrobial peptides that can inhibit closely related bacteria. One bacteriocin, designated mundticin L, produced by Enterococcus mundtii CUGF08 was found to inhibit Listeria spp. and other genera. Another bacteriocin, produced by Lactococcus lactis AA4 was found to be nisin Z. The genetic determinants for mundticin L, the associated ATP-binding cassette (ABC) transporter, and immunity protein were identified, cloned, and sequenced. Mundticin L was isolated and confirmed by N-terminal amino acid sequencing. The function of the immunity protein was analyzed by heterologous expression of the immunity gene in sensitive Gram-positive organisms. The immunity protein does not provide full protection. However, additional factors may be involved in this unusual phenotype. Genomic mutagenesis may reveal these factors. Thermal inactivation and biological control utilizing naturally occurring bacteriocinogenic LAB were investigated as potential decontamination strategies. Both methods showed potential in enhancing the safety of fresh sprouts. LAB as bioprotective cultures to enhance the safety of sprouts may serve a model as a "natural" or "green" hurdle for the safety of non-fermented produce.

This book was released on 2020-10-13 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The economic importance of lactic acid bacteria (LAB) for the food industry and their implication in health and disease has rendered them attractive models for research in many laboratories around the world. Over the past three decades, molecular and genetic analysis of LAB species provided important insights into the biology and application of starter and probiotic LAB and in the virulence of LAB pathogens. The knowledge obtained prepared LAB researchers for the forthcoming opportunities provided by the advent of microbial genomics. Today, developments in next-generation sequencing technologies have rocketed LAB genome research and the sequences of several hundreds of strains are available. This flood of information has revolutionized our view of LAB. First of all, a detailed picture has emerged about the evolutionary mechanisms allowing LAB to inhabit the very diverge ecological niches in which they can be found. Adaptation of LAB to nutrient-rich environments has led to degenerative evolution processes that resulted in shortening of chromosomes and simplified metabolic potential. Gene acquisition through horizontal transfer, on the other hand, is also important in shaping LAB gene pools. Horizontally acquired genes have been shown to be essential in technological properties of starters and in probiosis or virulence of commensals. Progress in bioinformatics tools has allowed rapid annotation of LAB genomes and the direct assignment of genetic traits among species/strains through comparative genomics. In this way, the molecular basis of many important traits of LAB has been elucidated, including aspects of sugar fermentation, flavor and odor formation, production of textural substances, stress responses, colonization of and survival in the host, cell-tocell interactions and pathogenicity. Functional genomics and proteomics have been employed in a number of instances to support in silico predictions. Given that the costs of advanced next-generation methodologies like RNA-seq are dropping fast, bottlenecks in the in silico characterization of LAB genomes will be rapidly overcome. Another crucial advancement in LAB research is the application of systems biology approaches, by which the properties and interactions of components or parts of a biological system are investigated to accurately understand or predict LAB behavior. Practically, systems biology involves the mathematical modeling of complex biological systems that can be refined iteratively with wet-lab experiments. High-throughput experimentation generating huge amounts of data on the properties and quantities of many components such as transcripts, enzymes and metabolites has resulted in several systems models of LAB. Novel techniques allow modelling of additional levels of complexity including the function of small RNAs, structural features of RNA molecules and post-translational modifications. In addition, researchers have started to apply systems approaches in the framework of LAB multispecies ecosystems in which each species or strain is considered as a part of the system. Metatransciptomics, metaproteomics and metametabolomics offer the means to combine cellular behavior with population dynamics in microbial consortia.
