  1. The sequence coverage (percentage of the protein sequence covered by identified peptides), unique peptides (number of peptide sequences that are unique to a protein), the protein ID, the expected molecular weight and the predicted protein function are reported for each identified protein. Proteins are listed in decreasing order of sequence coverage. Only proteins identified with the highest score (323.31) are listed. Identification was performed by using the annotated genome of P. sumatraense AQ67100 as reference database. Proteins specifically identified in AX-filtrate are highlighted in bold. All the remaining proteins were identified in AX- and at least in 1 out of 2 filtrates from algal-supplemented cultures. See Fig. 6 for further details on identified proteins
