Abstract
⺠Inverse response of 22S/(22S + 22R) ratio between extended hopane and its 25-norhopane as severe biodegradation occured. ⺠Abundance of 25-norhopanes showed a minor increase as hopanes decreased significantly. ⺠Alternative degradation pathways for hopanes might occur in a reservoir, besides C-25 demethylation. ⺠25-Norhopanes were formed prior to complete elimination of acyclic and bicyclic alkanes. ⺠Oil biodegradation in the subsurface was dominantly by anaerobic bacteria.
