Which organism hydrolyzes sodium hippurate to glycine and benzoic acid?

Explanation:
Hydrolyzing sodium hippurate tests for the enzyme hippuricase, which cleaves hippurate into glycine and benzoic acid. After incubation, glycine is detected (often with ninhydrin) by a color change, indicating a positive result. Streptococcus agalactiae is hippurate-positive, so it hydrolyzes hippurate to glycine and benzoic acid. This property is a useful identifier for Group B Streptococcus in clinical labs, helping distinguish it from other streptococci in routine workups. Therefore, among the organisms listed, this one is the classic hippurate-hydrolyzing performer.
