Title Amino acids in the sedimentary humic and fulvic acids
 
Creator Sardessai, Sugandha
 
Description 394-399
Humic and
fulvic acids isolated from a few sediment samples from Arabian Sea and Bay of Bengal were analysed for total hydrolysable amino
acids concentration and their composition. The amino acids content of fulvic
acids was higher than in the humic acids in the coastal Arabian Sea sediments;
whereas amino acids content of fulvic acids was lower than that of humic acids
in the coastal sediments of Bay of Bengal.
Slope sedimentary humic acids were relatively enriched in amino acids as
compared to the coastal sedimentary humic acids implying higher association of
amino acids with the carbonaceous

and fine grained sedimentary
humic acids. Both the humic and fulvic acids are composed of neutral, acidic,
basic, aromatic and sulphur containing amino acids. Low molecular weight, as
compared to higher molecular weight, fractions of humic acids indicated higher
abundance of amino acids. Lysine, aspartic acid and the straight chain-glycine
and alanine were the major basic, acidic and neutral amino acids, respectively.
