Figure 2From: Comparison of lignin derivatives as substrates for laccase-catalyzed scavenging of oxygen in coatings and filmsOxygen content in chambers with coated boards with lignin derivatives and with (A) or without (B) laccase. The chambers were flushed with fresh gas mixture (1% oxygen and 99% nitrogen) after three days (indicated by arrows). Error bars indicate standard deviations of three replicates.Back to article page
