1 Introduction Fungi have the ability to transform organic materials into a rich and diverse set of useful products and provide distinct opportunities for tackling the urgent challenges before all humans. Fungal biotechnology can advance the transition from our petroleum-based economy into a bio-based circular economy and has the ability to sustainably produce resilient sources of food, feed, chemicals, fuels, textiles, and materials for construction, automotive and...

Introduction Weaning events such as changes in diets, facilities, and littermates are among the factors that cause weaning stress. The weaning stress can lead to inflammatory activation in the intestine and damage of enterocytes [1, 2], reducing the digestibility of nutrients in feeds and nutrient absorption. It has long been demonstrated that pigs weaned at older ages are less susceptible to weaning stress and, thus, have improved feed intake and body weight gain [3–5]....

Introduction Fungal contamination in grains is a serious issue for modern animal production. Mold growth is associated with decreased nutrient content in animal feedstuff (Vieira, 2003). Furthermore, the development of fungi under specific conditions may lead to another major threat: mycotoxin production. In past decades, over one quarter of the world’s food crop production was estimated to be contaminated with mycotoxins (CAST, 2003). Mycotoxins are secondary fungal...

Deoxynivalenol (DON; vomitoxin) is a trichothecene mycotoxin that is produced by Fusarium graminearum (F. graminearum) and is prevalently found in grains such as wheat, corn, barley and their by-products. Food and feed contaminated with DON cause a variety of adverse health effects in humans and farm animals. Poultry are also adversely affected by DON but less susceptible due to differences in DON metabolism. Because of the differences in breeds, types of diet and strains of poultry,...

INTRODUCTION Mycotoxins are secondary metabolic products of fungi with toxigenic effects in other living species. Worldwide, about 88% of animal feed and feedstuffs are contaminated with at least one mycotoxin [1]. Fusarium toxins are the most prevalent, where deoxynivalenol ranks at first with 64% of occurrence, followed by fumonisins and zearalenone [1]. In pigs chronically fed deoxynivalenol contaminated diets, it is observed increased expression of interleukin 8 and...

1. Introduction Aspergillus fumigatus is a saprophytic fungus that can colonize diverse ecological niches facilitated by its great plasticity to adapt to different environments and the wide dispersal of its small, airborne spores called conidia [1,2]. The conidia allow A. fumigatus to reach all chambers of the human respiratory tract, where the fungus is able to cause a wide range of infections depending on the immune status of the patient [3–6]. The biological...

1. Introduction Aspergillus fumigatus is a saprophytic fungus implicated in nitrogen and carbon recycling. Typically of soil decomposers, it is capable of surviving in a wide range of conditions [1]. It has evolved to be a great competitor against other environmental microorganisms because it possesses a controlled nutritional flexibility to scavenge nutrients from the environment efficiently [2]. In addition to these characteristics, its abundant sporulation has gained it a...

Introduction The study of mycotoxins has been an object of interest for the world in the last twenty years, not only because of the large losses in crop and animal productivity but also because of their deleterious effects. Mycotoxins are considered the secondary metabolic product of a large number of fungi that in small amounts are capable of triggering alterations and pathological conditions in both humans and animals. The intake of food contaminated with mycotoxins may cause...

Dear all, at first we need to select: what is deactivation? Is it destroying? Or binding? Or we need to know how effective is liver P-450 in vivo against mycotoxins? How can we use binders if these binders can chemically react with vitamins? What is alternative? Grain without mycotoxins: is it possible? Probably not, and this is problem for everybody. Let's discuss!...

In 2021 mycotoxins annual survey, Life Rainbow Biotech randomly collected 393 feed samples of raw materials and feed mills in farms and analyzed. The samples were tested for aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3) and deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit. Results: From January to December 2021, the import volume of feed corn was 4,128 thousand tons, and the United States is 35.26%, followed by Brazil and Argentina for...

Introduction Fusarium head blight (FHB), also known as scab, is an economically devastating fungal disease of small-grain cereals such as wheat, barley and oat (Kulik et al., 2007). Fusarium graminearum is the major causal agent of this disease in many areas of the world, while in Europe other species such as F. culmorum, F. avenaceum and F. poae have been found frequently (Nicholson et al., 2003). Several researches have documented the increased importance of F. poae in some...

1. Introduction Mycotoxins are fungal-generated secondary metabolites that are ubiquitous and unavoidable contaminants of food and feed, and their consumption by humans and animals results in diseases and death. Several species of the genus Aspergillus, Penicillium, and Fusarium are capable of producing mycotoxins (Cole & Cox, 1981). For instance, Aspergillus flavus, A. parasiticus, A. nomius, and A. psudotamarii are responsible for the production of a series of highly toxic...
