Overview

This book focuses on probiotics and gut microbiota, as well as their roles in alleviating the toxicity of various environmental pollutants, presenting the latest research findings and explaining advanced research methods and tools. At the same time, it offers suggestions for future research directions. Further, the book introduces readers to the concept of gut remediation, a potential approach to reducing environmental-pollutant toxicity in vivo, based on modulation of gut microbiota using probiotic supplements. Lastly it provides suggestions for further reading.

Table of Contents

Chapter 1: Gut microbiotaSummary: The gut is a huge complex ecosystem where microbiota, nutrients, and host cells interact extensively, a process crucial for the gut homeostasis and host health. The gut microbiota has many functions including metabolic, barrier effect, and trophic functions. Hence, many diseases have been associated to impairment of the gut microbiota. This part provides in depth view of the close relationship between gut microbiota, health and disease.1.1Gut microbiota1.2Gut microbiota balance and health1.3Gut microbiota dysbiosis and diseaseChapter 2: Probiotics and gut microbiotaSummary: Probiotics, “live micro-organisms”, when consumed in adequate amounts, positively modulate the gut microbiota to prevent or treat some diseases. This part gives the interaction between probiotics and gut microbiota contributing to host health.2.1Probiotics2.2Probiotics and gut microbiota2.3 Probiotics and healthChapter 3: Probiotics, gut microbiota and heavy metalsSummary: The accumulation of heavy metals disrupts the structure of gut microbiota, causing damage to organs such as liver and kidney. Probiotics effectively protect against heavy metals toxicity by facilitating heavy metals excretion and mediating gut microbiota.3.1Common heavy metals (Cr, Cd, Hg, Pb, As, Cu, MeHg)3.2Other representative metals (Al, Zn, Ni)Chapter 4: Probiotics, gut microbiota and pesticidesSummary: Various pesticides lead to adverse effects on human health, such as oxidative stress and metabolism disorder of the gut microbiota. Probiotics protect against pesticides-induced oxidative stress and downstream cellular damage by enzymatically degrading pesticides, reducing the absorption of pesticides and stimulating host’s own immunity.4.1Organophosphorus pesticides (chlorpyrifos, malathion, diazinon, glyphosate)4.2Organochlorine pesticides (pentachlorophenol, permethrin)4.3Other pesticides (imazalil, carbendazim)Chapter 5: Probiotics, gut microbiota and antibioticsSummary: Antibiotics kill a large number of gut microbiota without prejudice, and improve the resistance of pathogenic bacteria such as Clostridium difficile. Antibiotic associated diarrhoea and Clostridium difficile infection can be common following antibiotics treatment. Probiotics have been widely reported to reduce the risks of antibiotics-induced side effects.5.1Antibiotics and gut microbiota5.2Effect of probiotics on antibiotics associated diarrhoea5.3Effect of probiotics on Clostridium difficile infection5.4Potential protective mechanism of probioticsChapter 6: Probiotics, gut microbiota and other persistent organic pollutantsSummary: Polycyclic aromatic hydrocarbons come from grilled or smoked meat and fish that is carcinogenic. The essential oil analogue has significant antimicrobial activity against gut microbiota, which causes abnormal metabolism of gut microbiota. However, probiotics can be used as an alternative method against mutagenesis caused by some persistent organic pollutants. Many food additives can be replaced by lactic acid bacteria. 6.1Polycyclic aromatic hydrocarbons (anthracene, naphthalene, phenanthrene, pyrene, benzo(a)pyrene)6.2 Food additives (sweeteners, emulsifiers, flavoring agents, coloring agents)Chapter 7: Gut microbiota, probiotics and biological contaminantsSummary: Some pathogenic organisms can invade the gastrointestinal tract, compete for nutrients and release toxins. Meanwhile, they can inhibit the normal growth and metabolism of the host’s native microbiota. Probiotic, such as Lactobacillus rhamnosus, has been reported to detoxify aflatoxin through modulate gut microbiota, fecal excretion in animals.7.1Mycotoxins7.2CyanotoxinsChapter 8: Gut remediationSummary: The phenomenon of alleviating the toxicity of environmental pollutants by regulating the composition and function of gut microbiota using probiotics is termed as “gut remediation”. Compared to current remediation technology, gut remediation appears to be a novel remediation approach to repairing tissue damage caused by various pollutants.8.1Gut remediation8.2The advantage of gut remediationChapter 9: ProspectiveSummary: An important consideration for probiotics is how to successfully introduce a/some strain with desired function and also robust colonization ability into recipient communities. This merit formulates probiotics regimen design based on a particular consumer at differing clinical contexts.
