Abstract:
Penicillium are very diverse and cosmopolite fungi, about 350 species are recognized within this genus. It is subdivided in four subgenera Aspergilloides, Penicillium, Furcatum, and Biverticillium; recently the first three has been included in Penicillium genus, and Biverticillium under Talaromyces. They occur worldwide and play important roles as decomposers of organic materials, cause destructive rots in the food industry where produces a wide range of mycotoxins; they are considered enzyme factories, and common indoor air irritants. In terms of human health are rarely associated as human pathogen because they hardly growth at 37°, while the main risk is related to ingestion of food contaminated by mycotoxins produced by several species of Penicillium. Various mycotoxins can occur in foods and feeds contaminated by Penicillium species, the most important are ochratoxin A and patulin; for which regulation are imposed in a number of countries, and at a less extent cyclopiazonic acid. In this chapter we summarize the main aspect of the morphology, ecology and toxigenicity of Penicillium foodborne mycotoxigenic species which belong mainly in subgenus Penicillium sections Brevicompacta, Chrysogena, Fasciculata, Penicillium, and Roquefortorum.
Insights
Penicillium fungi are widespread and produce mycotoxins like ochratoxin A and patulin, posing risks through contaminated food. This review covers their morphology, ecology, and toxigenicity in foodborne species.
Area of Science:
- Mycology
- Food Science
- Toxicology
Background:
- Penicillium fungi are diverse, cosmopolitan organisms with significant ecological and industrial roles.
- They are known decomposers, enzyme producers, and indoor air irritants.
- While rarely pathogenic due to limited growth at 37°C, they pose health risks via mycotoxin ingestion.
Purpose of the Study:
- To summarize the morphology, ecology, and toxigenicity of foodborne Penicillium species.
- To highlight key mycotoxins produced by Penicillium, including ochratoxin A and patulin.
- To focus on species within Penicillium subgenus, sections Brevicompacta, Chrysogena, Fasciculata, Penicillium, and Roquefortorum.
Main Methods:
- Literature review and synthesis of existing data on Penicillium species.
- Analysis of morphological characteristics relevant to identification and ecology.
- Assessment of ecological roles and toxigenic potential, focusing on food contamination.
Main Results:
- Penicillium species are classified into four subgenera, with Biverticillium now under Talaromyces.
- Major foodborne mycotoxins include ochratoxin A and patulin, subject to regulatory limits.
- Key toxigenic species belong to specific sections within the Penicillium subgenus.
Conclusions:
- Understanding Penicillium morphology, ecology, and toxigenicity is crucial for food safety.
- Regulatory control of mycotoxins like ochratoxin A and patulin is essential.
- Further research into Penicillium species impacting food is warranted.
