I do not know about quinones, but methyl esters of fatty acids may be readily extracted from the broth with dichloromethane or chloroform. If the phase separation is unsatisfactory, you may spin the biphasic mixture down or use 10% methanol in the solvents above. Polar lipids may be extracted analogously. However, negatively charged lipids that is, those possessing carboxylic or phosphodiester groups, are best extracted from acidic media. Adding sodium chloride will always help to extract fatty compounds.

Good luck with your project.
