Resuming on 103 for two, and looking to overhaul the visitors' 469, Mominul showed a sense of urgency in passing his hundred from just 98 balls before lunch on day three.
The left-hander was eventually dismissed just short of a double hundred on 181 but his stunning performance, coupled with useful contributions from Mushfiqur Rahim (67) and Nasir Hossain (46), saw Bangladesh dominate as they closed the day on 380 for seven - 89 runs behind their opponents.
