Amino acids and reef aquarium: Glycine
Representatives of 10 phyla removed significant quantities of glycine from solution during an observation period of 16 to 24 hrs (Stephens and Schinske 1961) Glycine is not essential nutritional amino acid for prawns (Cowey and Forster 1971) Most abundant DFAA in southern California coastal waters (Clark et al 1972, Carlucci et a 1984) Bivalve Mytilus edulis has very... »
Amino acids and reef aquarium: Glutamic acid
Glutamic acid was very successful feeding activator for stony coral Montastrea cavernosa, causing full envelopment on every trial (Lehman and Porter 1973) One of the predominant amino acids in costal surface water and has high heterotrophic turnover rate (Williams et al 1976) Main contributor to the bacterial intracellular amino acid pool, may compete with nitrate uptake... »
Amino acids and reef aquarium: Cysteine
Cysteine seems to be less interesting amino acid as it is found in only 11 abstracts out of 4300 scientific papers I have in my collection. There are some papers that discuss Cysteine as a part of special proteins in marine invertebrates but these are much too advanced (for me) or theoretical to apply... »
Amino acids and reef aquarium: Aspartic acid
Important carbon source for some bacteria strains (Macleod et al. 1954, Berland et al. 1970) Aspartic acid is not an essential amino acid for crustaceans (Cowey and Forster 1971) As a DFAA reduced in surface water but found in much more larger amount in bottom and interstitial water (Clark et al. 1972) Causes a slight feeding response... »
Amino acids and reef aquarium: Arginine
Arginine is essential amino acid for crustaceans, it cannot be synthesized by themselves (Cowey and Forster 1971). Arginine causes feeding response (including digestion) in stony coral but has a significantly delayed response (1-2 minutes). Activity is confined to the mouth region (Lehman and Porter 1973) Arginine is a major contributor to copepod and mysid free amino... »
Amino acids and reef aquarium: Alanine
Alanine is not essential amino acid for crustaceans (Cowey and Forster 1971). Alanine can elicit synthetic food retention in sea anemone tentacles but not mouth opening or digestion (Nagai and Nagai 1973) Present in natural seawater and is readily utilized by pelagic heterotrophic organisms (Williams et al. 1976) Common marine diatom Nitzschia laevis can utilize Alanine, uptake... »
Amino acids and reef aquariums
In this my first post about amino acids and reef aquariums I take a look at what products are available to hobbyists and what amino acids and vitamins they contain. Unfortunately there are still several manufacturers who do not have enough respect for amateur aquarists to include the list of ingredients for their products.... »
