Solid liquid separation of microbial product in industry using filtration and centrifugation techniques?

Filtration.

Explanation:

Filtration can be used to separate solid part from liquid part of microbial product because it is less time consuming. This filtration process can easily separate liquids from solid material by allowing liquids to pass through the small holes and collecting solid on the surface of sieve. centrifugation techniques are used to separate liquids of different densities so it can't separate solid from liquid, it can only be done by filtration process.

not too sure maybe olecranon process

i'd say that the moon rock is about 2.2 billion years old.
