Alkaline slant - Observation for Carbohydrate Utilization Pattern Test
Alkaline slant (red) and acid butt (yellow) with or without gas production - This indicates fermentation of glucose only. As glucose concentration is low, only small amount of acid is produced which gets oxidized rapidly on a slant surface.
