Abstract
Bengkalis district is one of the area dominated by peatlands. Most of peatland areas are
found along the coast and influenced by tides and low tides. Tides and low tides can cause
abrasion, affecting the microbial cells number and microbial diversity. This research aimed
to calculate the microbial cells number on abrasion peat soil on the coast of Bengkalis
Island. Soil samples were taken from shrubs (SM), peat boulder (BK), peatball (BG) and
sesai (SS). Calculation of the microbial cells number using the plate count method by pour
plate. Result showed that bacterial cells number ranged from 2,1-14,1 x105 CFU/g soil. The
fungi cells number ranged from 0,4-6,6 x104 CFU/g soil. Based on the result, it can be
concluded that the microbial cells number in locations that have not been affected by
abrasion is higher than that of post-abrasion areas.
