The campaign group FARE (Football Against Racism in Europe) said on Twitter that Taison's team mate and follow Brazilian Dentinho reported the insults to the referee and a stadium announcement was made.
Following UEFA-recommended protocol, the referee then took the players to the dressing-room for five minutes, FARE said, before dismissing Taison and restarting the game which Shakhtar won 1-0.
The third step of the protocol would have been to abandon the match.
"Third step not activated, victim of racism sent off," said FARE, which added that Dynamo fans also mocked a club campaign by displaying posters which said "Like to racism."
In 2015, Dynamo Kiev were ordered by UEFA to play two European matches behind closed doors after four black spectators were attacked at their stadium during a match against Chelsea. (Writing by Brian Homewood; Editing by Ken Ferris)
