Caption:
This image depicts a frontal view of two Petri dishes containing xanthine medium. The plate on the left was inoculated with Nocardia asteroides, while the plate on the right was inoculated with Nocardia otitidiscaviarum, formerly known as N. caviae. The ability of N. otitidiscaviarum to hydrolyze xanthine is demonstrated by a halo surrounding the colony, indicating a zone of xanthine degradation. In contrast, the N. asteroides colony shows no halo, indicating an absence of xanthine hydrolysis.
