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!
usually the larger the pearl the more it is valuable size can greatly impact on price for example a 1mm increase in the size of medium quality pearls can raise their price 100 % to 200 % south sea pearls usually larger than akoya and freshwater pearls whose average diameters tend to range from 9 19mm
