There are a number of bacteria that DO survive in harsh environments be it pH or temperature extremes or an environment that is very salty. Bacteria that don't survive in hars â¦ h conditions usually lose cell wall integrity and break apart, or lose all their intercellular fluid and shrivel up.
Akoya Pearls are the Classic Pearl Variety. The akoya pearl is a saltwater cultured pearl from the akoya oyster (Pinctada fucata martensii). Because akoya are the most abundant type of saltwater pearl with the longest cultured history, information on akoyas is abundant!
akoya pearls can cost several times more than freshwater pearls of similar quality and size one reason for this it that one mussel in a lake can produce as many as 40 freshwater pearls in one harvest season an oyster in the sea usually produces one or two saltwater pearls at a time
