[Growth conditions for toxin-forming fungi]
Abstract:
Moulds represent the biggest proportion in the number of approximately 250,000-300,000 species which belong to the kingdom fungi. Their role in nature and their different stages of multiplication on appropriate substrates are described. The conditions for multiplication of toxin-producing moulds are not principally different for non-toxogenic species. Most important for the multiplication of moulds are the following parameters: temperature, substrate composition, amount of light, gas compound; they are discussed. The quantitative results of mycological laboratory investigations of feed are given in the number of colony forming units (c.f.u.) per gram and can be interpreted in three categories: normal content (mostly not perished feed), increased content (mostly less fresh) and excessively high content (mostly perished). Often the results of the cultural investigation do not correspond with the investigation on mycotoxins. The reasons for that are mentioned.
Insights
Moulds, a major fungal group, multiply under various conditions. Their presence in feed, measured in colony forming units (c.f.u.), doesn't always correlate with mycotoxin levels.
Area of Science:
- Mycology
- Fungal Biology
- Environmental Microbiology
Context:
- Moulds constitute a significant portion of the estimated 250,000-300,000 fungal species.
- Understanding mould multiplication is crucial due to their ecological roles and potential for toxin production.
Purpose:
- To describe the role of moulds in nature and their multiplication stages.
- To outline the environmental conditions favoring mould growth, including toxin-producing species.
- To explain the interpretation of mycological feed analysis results and their limitations.
Summary:
- Mould multiplication depends on temperature, substrate, light, and gas composition, similar for both toxigenic and non-toxigenic species.
- Feed analysis quantifies mould content using colony forming units (c.f.u.) per gram, categorized as normal, increased, or excessively high.
- Discrepancies between mould counts and mycotoxin detection are common, with reasons discussed.
Impact:
- Provides insights into fungal ecology and factors influencing mould proliferation.
- Highlights the importance of considering environmental parameters for mould control.
- Clarifies the interpretation of feed mycology results and the need for complementary mycotoxin testing.
