What are the difference between water mold and mold growing the expired bread?

Answer 1

Water molds are typically oomycetes. Oomycetes are in teh calde Stramenopila. They are separated from Fungi (including bread molds) by the their use of the DAP pathway for lysine synthesis, the presence of cellulose in their cell walls, their tubular cisternae in the mitochondria, heterokont flagella on their zoospores, and lack of a Spitzenkorper in their hyphae.

Fungi use the AAA pathway for lysine synthesis, have chitin in their cell walls, have plate-like cisternae in the mitochondria, a single whiplash flagellum, and use a Spitzenkorper to elongate their hyphae.

Answer 2

Water mold is a type of mold-like organism that typically grows in waterlogged environments, while mold growing on expired bread is a fungus that thrives in warm and humid conditions, like on bread left out past its shelf life. Water mold poses a threat to aquatic organisms, whereas bread mold is a common household nuisance that can be harmful if ingested.
