What Does Gram-Positive Mean? | FermUp Gram-Postive

The name comes from its discoverer and inventor, Han Christian Gram (Gram, 1884). This stain will either stain the cells purple (for positive) or pink (for negative). Gram-positive bacteria have a very thick cell wall made of a protein called peptidoglycan.

Answer 2

Answer:

bacteria, isolated from oily sludge, were found to be able to tolerate pure and mixture of saturated hydrocarbons, as well as pure and mixture of monoaromatic and polyaromatic hydrocarbons. Isolated Gram-negative bacteria were more tolerant to mixture of saturated (n-hexane, n-hexadecane, cyclohexane), monoaromatic (benzene, toluene, ethylbenzene) and polyaromatic (naphthalene, 2-methylnaphthalene, fluorene) hydrocarbons than Gram-positive bacteria
