Isolation of Species Specific Bacteria from Raw Nature for Porcine Gelatin Detection

Abstract

The ability of gelatinase bacteria to hydrolyze gelatin makes them widely distributed and may have an impact on the safety and quality of gelatin manufacture. A study was conducted to find out specific species of gelatinase bacteria in 14 samples from selected sources using the agar isolation method through 1, 3 and 5% porcine gelatin. The samples are chosen from various types of soil, animal skin and water. The selection is made in the event of gelatinase activity on the agar surface. Findings were obtained with the 10 most active gelatinase bacteria characterized through culture morphology which were then isolated to see their sensitivity in the detection of Halal gelatin.
