The liberated H₂S reacts immediately with soluble iron salts (ferric ammonium citrate or ferrous sulfate) dissolved throughout the agar matrix to form insoluble black ferrous sulfide (FeS), producing the characteristic jet-black colouration localised to the colony and its immediate surroundings. Concurrent oxygen scavenging by sodium sulfite within the agar creates a locally reduced microenvironment that favours anaerobic growth, enhancing recovery of even low-density spore populations from water and food matrices without the absolute requirement for external anaerobic jar systems in some protocols.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003c!-- Clostridium \/ SRC Detection Comparison Table --\u003e\n    \u003cdiv style=\"margin-bottom: 35px;\"\u003e\n      \u003ch3 style=\"color: #1a1a2e;
