Probability models for growth and aflatoxin B1 production as affected by intraspecies variability in Aspergillus flavus [PDF]
, 2018 The probability of growth and aflatoxin B1 (AFB1) production of 20 isolates of Aspergillus flavus were studied using a full factorial design with eight water activity levels (0.84e0.98 aw) and six temperature levels (15e40 C).

Assessment of intraspecies variability in fungal growth initiation of Aspergillus flavus and aflatoxin B1 production under static and changing temperature levels using different initial conidial inoculum levels [PDF]
, 2018 Intraspecies variability in fungal growth and mycotoxin production has important implications for food safety. Using the Bioscreen C we have examined spectrophotometrically intraspecies variability of A.

Degradation of Aflatoxin by Aspergillus flavus
Microbiology, 1987 Aflatoxin degradative activity was demonstrated in 6- to 12-d-old intact mycelium and cell-free extracts of Aspergillus flavus. The addition of cycloheximide, SKF 525-A or metyrapone to cultures of A. flavus prevented subsequent degradation of the aflatoxins, while in cell-free extracts degradation was inhibited by SKF 525-A, metyrapone and cytochrome ...

Cyclopiazonic Acid Biosynthesis of Aspergillus flavus and Aspergillus oryzae [PDF]
Toxins, 2009 Cyclopiazonic acid (CPA) is an indole-tetramic acid neurotoxin produced by some of the same strains of A. flavus that produce aflatoxins and by some Aspergillus oryzae strains. Despite its discovery 40 years ago, few reviews of its toxicity and biosynthesis have been reported.

Integrating gene expression, ecology and mycotoxin production by Fusarium and Aspergillus species in relation to interacting environmental factors [PDF]
, 2016 Environmental factors, such as water availability (water activity, aw), temperature and their interactions, have a significant impact on the life cycle of mycotoxigenic fungi.

Using Staged Tree Models for Health Data: Investigating Invasive Fungal Infections by Aspergillus and Other Filamentous Fungi [PDF]
arXiv, 2023 Machine learning models are increasingly used in the medical domain to study the association between risk factors and diseases to support practitioners in predicting health outcomes. In this paper, we showcase the use of machine-learned staged tree models for investigating complex asymmetric dependence structures in health data.

Generic model of morphological changes in growing colonies of fungi [PDF]
Phys. Rev. E 65, 021903 (2002), 2001 Fungal colonies are able to exhibit different morphologies depending on the enviromental conditions. This allows them to cope with and adapt to external changes. When grown in solid or semi-solid media the bulk of the colony is compact and several morphological transitions have been reported to occur as the external conditions are varied.

An attempt to model the probability of growth and aflatoxin B1 production of Aspergillus flavus under non-isothermal conditions in pistachio nuts [PDF]
, 2015 Human exposure to aflatoxins in foods is of great concern. The aim of this work was to use predictive mycology as a strategy to mitigate the aflatoxin burden in pistachio nuts postharvest.
