Which fungus is known as 'Green Mold'?

The correct answer is Penicillium.

Key Points

• Penicillium is a genus of fungi known for its role in the production of antibiotics, most notably penicillin.
• Penicillium species are commonly referred to as "Green Mold" due to their characteristic blue-green color.
• These fungi are found in various environments, including soil, decaying vegetation, and indoor environments.
• Penicillium notatum and Penicillium chrysogenum are particularly well-known for their role in the discovery and production of penicillin.
• Penicillium plays a vital role in the food industry, particularly in the ripening of cheeses like Roquefort and Camembert.

Additional Information

• Antibiotics:
  • Penicillin, derived from Penicillium, was the first true antibiotic discovered by Alexander Fleming in 1928.
  • Antibiotics are substances that can destroy or inhibit the growth of bacteria and are used to treat bacterial infections.
  • Penicillin works by interfering with the synthesis of the bacterial cell wall, leading to the death of the bacteria.
• Mycotoxins:
  • Penicillium species can produce mycotoxins, which are toxic compounds that can contaminate food and pose health risks.
  • Common mycotoxins produced by Penicillium include patulin and ochratoxin A.
• Food Industry:
  • Penicillium is used in the production of certain cheeses, adding distinct flavors and textures.
  • Penicillium roqueforti is used in blue cheeses, whereas Penicillium camemberti is used in soft cheeses like Camembert and Brie.
• Fungal Reproduction:
  • Penicillium reproduces asexually through the production of conidia, which are spores that disperse and germinate in suitable environments.
  • These spores contribute to the characteristic mold appearance on various surfaces.
