What is a gram popstive and gram negative cell wall?
After Christian Gram developed the Gram stain in 1884, it soon became evident that bacteria could be divided into two major groups based on their response to the Gram-stain procedure. Gram-positive bacteria stained purple, whereas gram-negative bacteria were colored pink or red by the technique. The true structural difference between these two groups became clear with the advent of the transmission electron microscope. The gram-positive cell wall consists of a single 20 to 80 nm thick homogeneous peptidoglycan or murein layer lying outside the plasma membrane. In contrast, the gram-negative cell wall is quite complex. It has a 2 to 7 nm peptidoglycan layer surrounded by a 7 to 8 nm thick outer membrane. Because of the thicker peptidoglycan layer, the walls of gram-positive cells are stronger than those of gram-negative bacteria. Microbiologists often call all the structures from the plasma membrane outward the envelope or cell envelope. This includes the wall and structures like capsules when present.
What is a gram positive aerobic bacteria which uses citrate and dextrose?
I think that there are two possible answers....first, Nocardia and, also, Bacillus anthracis. Lactobacillus might also work; however it is a microaerophilic organism and can only tolerate lesser levels of oxygen than a true aerobic organism. But all three are gram positive and, I believe, thrive with both dextrose and citrate. Nocardia has a Trycarboxylic acid cycle which utilizes both dextrose and citrate.
