| b1481 | Orf, hypothetical protein | 4.0 |
| ykgM | Putative ribosomal protein | −2.9 |
| upp | Uracil phosphoribosyltransferase | −3.2 |
| treC | Trehalase 6-P hydrolase | −3.5 |
| yifE | Orf, hypothetical protein | −4.0 |
| lamB | Phage lambda receptor protein; maltose high-affinity receptor | −4.5 |
[i] The log2 fold change was calculated as log2(gene expression with salt treatment)/(gene expression with no treatment).
