In sufficiently high concentrations,
these by-products will inhibit microorganisms,
bacteria as well as yeasts. While relatively high concentrations
of aliphatic acids and furan aldehydes are required to
negatively influence yeast, some phenolic compounds are
strongly inhibitory even at low concentrations [17,18].
With regard to G. xylinus, it is well known that detoxification
of lignocellulosic hydrolysates may be required to
achieve efficient production of BC [10].
