Shrimp bacteria species

The hydrothermal vent shrimp, Rimicuris exoculata, which is known to be a primary consumer of the chemolithoautotrophic bacteria, contained 13 pg/g of arsenic almost exclusively as arsenobetaine 54. The major parts of the extractable arsenic species in the adductor muscle/mantle tissues and in the gill were present as riboside derivatives 56 and 57, while 54 was present at 16% and 3.6%, respectively, in these tissues... 

Once fertilization occurs, crustacean embryos are commonly carried and tended by the female. In some shrimp and lobster species, the embryos are chemically protected from microbial pathogens by symbiotic microbes covering the embryo surfaces and producing chemicals that prevent attack by harmful microbes. In the shrimp Palaemon macrodactylus and the lobster Homarus americanus, symbiotic bacteria on the embryo surfaces produce 2,3-indolinedione (isatin) and... 

The UCB group also performed triazine EIAs on samples from agricultural evaporation ponds in the San Joaquin Valley. These ponds collect drainage from fields where triazines may be used, and thus have the potential for accumulating these, and other pesticides. Metal ions, salts, and suspended solids accumulate in amounts up to 20 times those found in sea water, and various species of bacteria, algae and even brine shrimp may propagate in water from these... 

The copolymers were tested for toxicity against two different species of bacteria viz., aeruginosa and lutea. A bioassay of these compounds was also performed on brine shrimp A. salina, whose life cycle resembles that of barnacles, a severe fouling organism.
