SpletMany gram neg rods are considered enteric or "gut" bacteria (called enterobacteriaceae) and use aerobic respiration. The non-enterobacteriaceae aerobic gram neg rods (non-gut bugs) can be further categorized by their fermentation patterns. Review the list below to familiarize yourself with the overall categorization of these bacteria. SpletGram-negative bacteria have cell walls with thin layers of peptidoglycan (10% of the cell wall) and high lipid (fatty acid) content. This causes them to appear red to pink under a Gram stain. Gram-negative organisms include: Neisseria gonorrheae and Neisseria meningitides. Moraxella species. Escherichia coli (E. coli). Pseudomonas species. SpletIt tests an organism's ability to ferment the sugar glucose as well as its ability to convert the end product of glycolysis, pyruvic acid into gaseous byproducts. This is a test commonly used when trying to identify Gram-negative enteric bacteria, all of which are glucose fermenters but only some of which produce gas. book royal scotsman
