A study was conducted to determine the amino acid variations in Tylenehorhynehus bravilineatus collected from different altitudes (100m, 450m, 525m & 1900m above sea level) around the soils of some economically important plants in two agro-ecological environments i.e. Allahabad (plain) and Pauri-Garhwal (hilly regions). It was interesting to note that the maximum (14) amino acids were detected at Allahabad in comparasion to other places. The amino acids common to all the altitudes were glycine, hydroxyproline, leucine, and serine. Arginine and tyrosine were exceptionally present at 100 m ASL whereas aspartic acid, phenylalanine and threonine were absent at the same altitude in T. bravilineatus in comparasion to other places. Glutamic acid and ornithine were present at both the extremes. Threonine was exceptionally present in the worm isolated from the soil of Kotdwara (hilly region). The common amino acids detected in high altitude were glycine, hydroxyproline, leucine, phenylalanine and serine.
