Biocontrol Agents and Natural Compounds against Mycotoxinogenic Fungi by Florence Mathieu,Selma P. Snini Pdf

Mycotoxins are toxic secondary metabolites produced by fungi. They cause deleterious effects on humans, animals, and plants. More than one hundred mycotoxins are known which contaminate food and feed raw materials. Fungal infection and mycotoxin contamination can occur directly in fields (pre-harvest stage), during storage, or during industrial processing (post-harvest stage). Given the proven toxicity of mycotoxins and their widespread distribution, it is necessary to prevent their occurrence in food and feed. To limit mycotoxin contamination, several techniques can be adopted at the pre-harvest or post-harvest stages. These techniques can reduce mycotoxin concentration through fungal growth reduction or mechanisms leading to mycotoxin degradation or mycotoxin detoxification (i.e., reduction of the toxicity). Until very recently, fungicides were favored to limit mycotoxin contamination by reducing fungal growth. Nonetheless, the sanitary and environmental impacts of these products and their effects on food quality encourage the development of alternative strategies based on biocontrol agents (BCAs) or natural compounds. Moreover, in some cases, fungal growth reduction can stimulate mycotoxin production. The focus of this Special Issue of Toxins is to gather the most recent advances related to reducing mycotoxin contamination in food and feed using BCAs and natural compounds. In this context, two main types of approaches can be proposed: Preventive methods that could be applied in the field, during storage, or during industrial processing and curative methods that detoxify contaminated matrices by eliminating the produced mycotoxin.

Mycotoxins in Food and Beverages by Didier Montet,Catherine Brabet,Sabine Schorr-Galindo,Ramesh C. Ray Pdf

Mycotoxins are secondary metabolites produced by fungi in a wide range of foods (cereals, peanut, tree nuts, dried fruits, coffee, cocoa, grapes, spices...) both in the field and after harvest, particularly during storage. They can also be found in processed foods of plant origin, or by transfer, in food products of animal (milk, eggs, meat and offal). Mycotoxins are of major concern since they can cause acute or chronic intoxications in both humans and animals which are sometimes fatal. Many countries, particularly in Europe, have set maximum acceptable levels for mycotoxins in food and feed. The book reviews the latest literature and innovations on important aspects of mycotoxins, e.g. mycotoxin producing fungi and the related ecosystems, mycotoxin occurrence, toxicity, analysis and management. Quantitative estimation of impacts of climate change on mycotoxin occurrence have been made recently, using predictive modelling. There is also a growing interest in studying the occurrence and toxicity of multiple mycotoxins in food and feed, including emerging or modified forms of mycotoxins. Innovative tools have also developed to detect and quantify toxinogenic fungi and their toxins. In order to reduce the use of chemicals that are harmful to the environment and health of consumers, alternative methods of prevention and decontamination of mycotoxins were tested in pre- and post-harvest, using microorganisms, natural substances or radiation treatments.

Applied Microbiology by A. Durieux,J.-P. Simon Pdf

This book illustrates the major trends in applied microbiology research with immediate or potential industrial applications. The papers proposed reflect the diversity of the application fields. New microbial developments have been done as well in the food and health sectors than in the environmental technology or in the fine chemical production. All the microbial genera are involved : yeast, fungi and bacteria. The development of biotechnology in parallel with the industrial microbiology has enabled the application of microbial diversity to our socio-economical world. The remarkable properties of microbes, inherent in their genetic and enzymatic material, allow a wide range of applications that can improve our every day life. Recent studies for elucidating the molecular basis of the physiological processes in micro-organisms are essential to improve and to control the metabolic pathways to overproduce metabolites or enzymes of industrial interest. The genetic engineering is of course one of the disciplines offering new horizons for the « fantastic microbial factory » . Studies of the culture parameter incidence on the physiology and the morphology are essential to control the response of the micro-organisms before its successful exploitation at the industrial scale. For this purpose, fundamental viewpoints are necessary. Development of novel approaches to characterise micro-organisms would also facilitate the understanding of the inherent metabolic diversity of the microbial world, in terms of adaptation to a wide range of biotopes and establishment of microbial consortia.

Principles of Plant-Microbe Interactions by Ben Lugtenberg Pdf

The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.

Agricultural Applications by F. Kempken Pdf

In this volume the relevance of fungi for agriculture is discussed in four sections. The first one 'Food and Fodder Production' concerns the application and potential of mushrooms, straw enrichment, and food or crop spoilage. The next section 'Mycotoxins and Detoxification' deals with the biosynthesis of mycotoxins and the use of fungi in organopollutant degradation. A large section entitled 'Disease Control, Diagnostic, and Management' covers various aspects of biological control (fungi, insects, and weeds), diagnostics with emphasis on the example of Magnaporthe grisea, and disease management with focus on the important fungal pathogens Phoma, Fusarium, rusts and powdery mildew. The last section 'Update on Host-Parasite Interactions' discusses signal transduction, avirulence determinants, phytotoxins, cell wall degradation, and the coevolution of pathogenic fungi and grass hosts.

Fumonisins in Food by Lauren S. Jackson,Jonathan W. DeVries,Lloyd B. Bullerman Pdf

The contents of this book are the proceedings of the ACS symposium, "Fumonisins in Food," which was held April 4-6, 1995, at the American Chemical Society National Meeting in Anaheim, CA. This symposi"Qm, which was international in scope, brought together researchers from diverse backgrounds in academia, government, and industry. Thirty-three speakers discussed topics ranging from the analysis offumonisins to toxicology and regulatory aspects. The fumonisins became the spotlight of mycotoxin research in 1988, when re searchers at the South African Medical Research Council isolated and structurally charac terized the fumonisins. Since 1988, there has been an explosion in the numbers of papers dealing with fumonisin-related topics. The interest in the fumonisins has arisen for several reasons. First, fumonisins are found in measurable concentrations in corn grown throughout the world. Second, these compounds have been implicated as the causative agents in a variety of naturally occurring animal diseases. Finally, there is speCUlation that fumonisins may in part be responsible for the high incidence of esophageal cancer in regions of the world in which corn is the staple grain.
