Book Description
It is generally assumed that microorganisms synthesize, release, detect and respond to small signaling hormone-like molecules. These molecules are used for a process termed “quorum sensing” (QS), a phenomenon that enables bacteria to sense when the minimal number of cells, or “quorum,” is achieved for a concerted response to be initiated. Words such as “language” and “behavior” are frequently used to depict QS in the literature. More simply put, language and cross-talk between bacteria, and between bacteria and animal or plant hosts, determines the behavior (e.g., beneficial or pathogenic effects) of bacteria. Currently, the major concern is to understand and decode this language. Overall, bacterial cross-talk was mainly studied on environmental, plant, and human pathogenic bacteria. Few studies considered food-related lactic acid bacteria. The cross-talk between bacteria influences the behavior and, in turn, the environmental adaptation and phenotypes. Therefore, it is understood that bacterial cross-talk has important applicative repercussions. The language spoken between bacteria populating the same food ecosystem may condition the phenotypic traits of starter lactic acid bacteria and, consequently, their performance. This Brief aims to define the basis of cell-to-cell signalling in food fermentation and will highlight: (i) microbiology, nutritional, chemical and functional aspects; (ii) functional properties due to microbial adaptation to the gastrointestinal tract; (iii) principal phenotypes under control of QS circuitries; (iv) quorum quenching. This Brief will be the first reference on this topic and it will highlight the main results for a more productive industrial application. Draft content 1. Signals of food related Gram-negative and Gram-positive bacteria The chapter will describe the different signaling languages used by Gram-negative bacteria (N-acyl-L-homoserine lactones) and Gram-positive bacteria (based on the synthesis of post-translationally modified peptides) and the universal chemical lexicon, shared by both Gram-positive and -negative bacteria (autoinducer-2 through the activity of the LuxS enzyme). 2. Phenotypes related to quorum sensing The chapter will describe the bacterial phenotypes, such as virulence, biofilm maturation, bacteriocin synthesis, and secondary metabolite production under control of QS circuitries. 3. Cell-to-cell signalling in fermented food: sourdough The chapter will describe the language spoken between bacteria populating the same food ecosystem (sourdough) and will provide an overview of the conditioned phenotypic traits of starter lactic acid bacteria and, consequently, their performance. 4. Cell-to-cell signalling in fermented food: yoghurt The chapter will describe the language spoken between bacteria populating the same food ecosystem (yoghurt) and will provide an overview of the conditioned phenotypic traits of starter lactic acid bacteria and, consequently, their performance. 5. Probiotic message at the intra-, inter-species and inter-kingdom level The chapter will describe the mechanisms that regulate the interaction between microorganism and host, and the capacity of the microorganism to adapt to environment. Particular reference will also be made to: (i) pathogen inhibition and restoration of microbial homeostasis through microbe-microbe interactions; (ii) enhancement of epithelial barrier function; and (iii) modulation of immune responses. 6. New Perspectives of quorum sensing This chapter will provide an overview of the future perspective regarding quorum sensing, showing that bacterial cross-talk may have important applicative repercussions. It will highlight the interference on the language of QS, which is defined as quorum quenching (QQ). Increasing translation of the bacterial cross-talk has shown that in some environmental circumstances, quenching of the language may occur.

Book Description
Lactic acid bacteria (LAB) are a diverse group of bacteria that comprise low GC content Gram-positive cocci or rods that produces lactic acid as the major end product of the fermentation process. Bifidobacterium genera may also be considered as a part of the LAB group for possessing some similar phenotypical characteristics despite the higher GC content. The key feature of LAB metabolism is efficient carbohydrate fermentation. This contributes to the production of several microbial metabolites that result in the improvement of flavor and texture of fermented foods, in addition to its positive impact on the human health when LAB is administered as a probiotic. The book deals with advances made in the functionalities of LAB, such as their effect on vitamin D receptor expression, impact on neurodegenerative pathologies, production of B-vitamins for food bio-enrichment, production of bacteriocins to improve gut microbiota dysbiosis, production of metabolites from polyphenols and their effects on human health, effect on reducing the immunoreaction of food allergens, as biological system using time-temperature to improve food safety, and the use of probiotics in animal feed. The book also reviews the use of LAB and probiotic technologies to develop new functional foods and functional pharmaceuticals.

Book Description
In complex microbial ecosystems constituted by a mixture of different species and strains, interactions will occur between individual micro-organisms. The general environment from which raw food products originate and the microbiological quality of the products in its processed state admits yeast growth. Moreover, the types of interaction found in mixed populations of micro-organisms are classified as direct or indirect interactions. Indirect interaction such as competition, commensalism, mutualism, amensalism or antagonism and neutralism; and direct interaction to predation and parasitism could be occurring. This book examines such interactions in fermented foods and beverages, which develop their nutritional and organoleptic qualities as a result of the metabolic activity of a succession of different micro-organisms. Furthermore, it is known that many microbes use extracellular signals to transmit information about population density and environmental conditions. The authors examine the process as microbes continually respond to varying medium conditions, in which quorum-sensing regulation that is modulated by physical factors and nutrients availability affect the interactions produced between micro-organisms.

Book Description
Traditional foods such as red meat and beer have unique, recognizable and desirable sensory traits. However, public awareness about health and the climate crisis is now driving consumers and governmental organizations to consume less meat and alcohol. These recognizable flavors are either missing in novel foods because the material is different (plant-based) or removed after the fermentation process. Therefore, there is a need for innovation of the flavor, texture and trigeminal sensations to meet the expectations for the expanding consumer groups. Improvements with proteins and microbial fermentation processes are currently in the process of making novel foods a global commercial success. For example, recent progress in plant-based foods has focused on the production of proteins that may lead to umami flavors and precursors that are transformed into savory flavor compounds in the cooking process. New non-conventional yeast species provide a very promising route to bioflavoring of foods and beverages. In addition, the nutritious value of foods can be dramatically improved by introducing new pathways that produce vitamins and micronutrients, for example for vulnerable groups, such as elderly people with a limited diversity of food choice. The functionality of the food may also be increased by the release/synthesis of bioactive compounds with functional potential (antimicrobial, antioxidant, immunomodulatory activities etc.).
