Answer 1

$\huge\boxed{\displaystyle \rm\green{Answer}}$

Almost all commercially available bacteria blends only contain a mix of Bacillus. Bacillus is an excellent treatment of bacteria in wastewater but is best suited for treating fats, oils, greases, and proteins. That is why they are primarily used in wastewater treatment plants.

Answer 2

Answer:

Methanogenesis or biomethanation is the formation of methane by microbes known as methanogens. Organisms capable of producing methane have been identified only from the domain Archaea, a group phylogenetically distinct from both eukaryotes and bacteria, although many live in close association with anaerobic bacteria.
