Complementation of crt1 deletion by overexpression of the RUT-C30 version of CRT1 or by heterologous transporters. a Protein secreted into medium by \(\Delta\)crt1 strain expressing different transporters and grown in minimal medium with indicated carbon sources. b Cellulase activities from cultivation of the same strains, measured as methylumbelliferyl-\(\upbeta\)-d-lactoside (MULac) hydrolysis. Colors and symbols are same as in a. Error bars in a, b present standard deviation between 2 growth replicates of two biological replicates (n = 4). c Cell dry weights of the strains with trMM-CB 2% as carbon source. Error bars present standard deviation between three independent experiments
