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!
Saltwater pearls include the akoya cultured pearls grown in Japanese and Chinese waters. They range in size from the tiny 2mm to the rare 10mm and are usually white or cream in color and round in shape. Australia, Indonesia, and the Philippines produce the South Sea pearl - the largest of all the pearls.
