Effect of salinity on amino acid composition of the marine fungus Cirrenalia pygmea

Cirrenalia pygmea, a mangrove fungus, was grown at various salinities and its amino acid composition determined. Higher salinity led to an increase in the amino acid pool size and the number of amino acids produced. Acidic amino acids were present in higher concentrations at 6.9‰ and 20.7‰ salinitie...

Description
Summary:Cirrenalia pygmea, a mangrove fungus, was grown at various salinities and its amino acid composition determined. Higher salinity led to an increase in the amino acid pool size and the number of amino acids produced. Acidic amino acids were present in higher concentrations at 6.9‰ and 20.7‰ salinities. Gln, His, Thr, Arg and Val were present only when the fungus was exposed to high salinity conditions. The concentration of Gly increased with salinity. Arginine and ornithine were present in low salinity, but in high concentrations at higher salinities. Proline and Dragendorff-positive compounds were absent.
