Alicyclobacillus contaminans is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated during a survey from both orange juice, and soil in Fuji City, Japan. The species was first described in 2007, and the name is derived from the Latin contaminans (contaminating).[1]
