“…The proposed method reported by Foroughi et al in 2018 consists of immobilizing yeast such as Saccharomyces cerevisiae on perlite support to detoxify AFM1-contaminated milk [146]. The results showed a significant reduction in AFM1 concentration for all tested milk samples with various initial AFM1 contents.…”

Aflatoxins (AF) are carcinogenic metabolites produced by different species of Aspergillus which readily colonize crops. AFM1 is secreted in the milk of lactating mammals through the ingestion of feedstuffs contaminated by aflatoxin B1 (AFB1). Therefore, its presence in milk, even in small amounts, presents a real concern for dairy industries and consumers of dairy products. Different strategies can lead to the reduction of AFM1 contamination levels in milk. They include adopting good agricultural practices, decreasing the AFB1 contamination of animal feeds, or using diverse types of adsorbent materials. One of the most effective types of adsorbents used for AFM1 decontamination are those of microbial origin. This review discusses current issues about AFM1 decontamination methods. These methods are based on the use of different bio-adsorbent agents such as bacteria and yeasts to complex AFM1 in milk. Moreover, this review answers some of the raised concerns about the binding stability of the formed AFM1-microbial complex. Thus, the efficiency of the decontamination methods was addressed, and plausible experimental variants were discussed.

“…The immobilization of S . cerevisiae has provided a decontamination process with a higher performance because of its practical benefits compared with a traditional free cell system (Foroughi et al ; Rahaie et al ). The cell immobilization technique provides a continuous decontamination process as well as higher yeast cell densities and metabolic activity in the biofilter, which leads to a shorter AF decontamination time (Verbelen et al ).…”

This study was aimed to investigate the immobilization of Saccharomyces cerevisiae on two different types of ceramic beads (activated alumina and alumina silicate) and comparing the supports for reduction aflatoxin M1 (AFM1) in vitro. The immobilization of S. cerevisiae was done on ceramic beads for 24 and 48 hr. The best immobilization was achieved at 48 hr. The images of scanning electron microscope confirmed that the immobilization of yeast cells on the activated alumina was better than the alumina silicate (P < 0.05). The ceramic beads with immobilized yeasts were applied to remove the AFM1 from contaminated standard liquid (0.2 µg/L) by 5, 10, and 20 min circulation time. Results showed that the AFM1 concentration in the solution after 20 min circulation was minimal and the highest AFM1 reduction was 75%, when the contaminated solution passed through the activated alumina beads. There was no Si or Al residue in standard liquid. Practical applications This study indicated that the activated alumina and alumina silicate can provide a perfect support for immobilization and the immobilization of Saccharomyces cerevisiae cells on ceramic beads can be used practically to detoxify AFM1‐contaminated liquid food.

“…was enhanced by cell immobilized onto perlite (Emtiazi et al 2005). A column system using perliteimmobilized Saccharomyces cerevisiae as stationary phase was designed for the decontamination of a atoxin M1 in milk (Foroughi et al 2018). Perlite was selected as the best support material for the immobilization of Mycobacterium austroafricanum IFP 2012 that was capable of mineralizing methyl tert-butyl ether (Lyew et al 2007).…”

Objectives Enhance androstadienedione (Androst-1,4-diene-3,17-dione, ADD) production of rough-type morphotype Mycolicibacterium neoaurum variant by repeated-batch fermentation of immobilized cells. Results M. neoaurum R was a rough colony morphotype variant, obtained from routine plating of smooth M. neoaurum strain CICC 21097. M. neoaurum R showed rougher cell surface and aggregated in broth. The ADD production of M. neoaurum R was notably lower than that of M. neoaurum CICC 21097 during the free cell fermentation, but the yield gap could be erased after proper cell immobilization. Subsequently, repeated-batch fermentation by immobilized M. neoaurum R was performed to shorten the production cycle and enhance the bio-production efficiency of ADD. Through the optimization of the immobilization carriers and the solvents for phytosterols, the ADD productivity of M. neoaurum R immobilized by semi-expanded perlite reached 0.075 g/L/h during the repeated-batch fermentation for 40 days. Conclusions Although smooth strains that could homogenously suspended in broth seemed to be preferred in the steroid bioconversion, the rough-type strain M. neoaurum R might be able to find their place by proper cell immobilization.
