aSecretomic analysis based on spectral counting. A quantitative analysis was conducted for samples grown on cellulose or SCB (mean of triplicates), while a semiquantitative analysis for samples grown on glucose or glycerol (one replicate) was performed. The complete protein reports are given in Additional file 3
bThe secretion of each protein was verified by the softwares SignalP, SecretomeP and YLoc. When at least two of three softwares give a positive result the protein was considered secreted
