“…Numerous studies have shown that pure or heterogenous microbial cultures isolated from different environments are capable of irreversibly transforming DON and other mycotoxins into less toxic compounds [15]. Composting alone or in combination with anaerobic digestion has also been shown to be an effective method of removing mycotoxins from contaminated substrates [16,17,72]. For example, 90 days of co-composting the organic fraction of municipal solid waste with corn artificially contaminated with AFB1 almost completely removed the mycotoxin [17].…”

“…However, most studies on mycotoxin degradation only tested the ability of isolated strains of bacteria or fungi under in vitro conditions, not in realistic scenarios [15]. To the best of our knowledge, the ability of the composting process to degrade mycotoxins has only been tested for aflatoxin B1 [16,17]. Moreover, there are other mycotoxins that are considered chemically stable and heat resistant [18,19].…”

Although toxicogenic moulds have been identified in municipal waste and composting facilities, only a few reports exist on the occurrence of mycotoxins in compost. Those reports mostly concern sewage sludge as a substrate, tested only a limited range of mycotoxins, and did not monitor the production of mycotoxins during the composting process. Therefore, this study aimed to investigate whether mycotoxins are produced during composting of selectively collected kitchen and garden waste. The study was carried out at pilot scale (550 L reactor with passive aeration). Kitchen waste (59.0% w/w), garden leaves (28.2%), and wood chips (12.8%) were used as a substrate, which was sampled every five days to determine its basic physicochemical characteristics (temperature, moisture, size-fraction content, loss on ignition) and respirometric activity (AT4). The substrate and leachate samples were also tested for the content of eight mycotoxins by HPLC-MS/MS. To screen the local compost market, commercial organic-compost samples were analysed for mycotoxin contamination. The substrate was successfully stabilized after 45 days (thermophilic peak of 62.6 °C, 40.4% mass reduction, 26.9% loss of organic matter, increase in the share of particles in the smallest size fraction, AT4 of 9.82 g O2/kg). Although the substrate was colonised by moulds at an early stage, only trace amounts of mycotoxins were detected in a few samples. Similarly, little or no mycotoxins were found in the commercial compost. Our results suggest a low risk of mycotoxin contamination in biowaste compost produced under appropriate technological conditions. Future research should focus on screening compost produced at smaller scales (e.g., in agricultural/residential compost piles) and on identifying factors associated with the risk of mycotoxin contamination in compost.

“…The possible destruction of mycotoxins directly in AD under the action of anaerobic biocatalysts of methanogenesis should be taken into account in the case of incomplete detoxification of mycotoxins contained in bird droppings at the stage of its alkaline pretreatment. It is known that the destruction of mycotoxins can be carried out by a number of microorganisms involved in AD when various polluted substrates are used in the process [ 18 , 24 , 79 , 80 , 81 , 82 , 83 , 84 , 85 ]. The success of their effect on mycotoxins is due to the fact that they have a number of enzymes capable of catalyzing the transformation of mycotoxins ( Table 4 ) [ 81 , 82 , 83 , 84 , 85 ].…”

To reduce the toxicity of modern feeds polluted by mycotoxins, various sorbents are added to them when feeding animals. A part of the mycotoxins is excreted from the body of animals with these sorbents and remains in the manure. As a result, bulk animal wastes containing mixtures of mycotoxins are formed. It is known that it is partially possible to decrease the initial concentration of mycotoxins in the process of anaerobic digestion (AD) of contaminated methanogenic substrates. The aim of this review was to analyze the recent results in destruction of mycotoxins under the action of enzymes present in cells of anaerobic consortia catalyzing methanogenesis of wastes. The possible improvement of the functioning of the anaerobic artificial consortia during detoxification of mycotoxins in the bird droppings is discussed. Particular attention was paid to the possibility of effective functioning of microbial enzymes that catalyze the detoxification of mycotoxins, both at the stage of preparation of poultry manure for methanogenesis and directly in the anaerobic process itself. The sorbents with mycotoxins which appeared in the poultry wastes composed one of the topics of interest in this review. The preliminary alkaline treatment of poultry excreta before processing in AD was considered from the standpoint of effectively reducing the concentrations of mycotoxins in the waste.
