there is an evidence that Exopolyphosphat of Pseudomonas aeruginosa is essential for flagellum dependent swimming and swarming motility. the author evaluated a WT,DppX and DppxC strain on LB medium plate and incubated at 37uC for 24h. the swimming motility of Dppx was 55-75%less than WT. the Dppx strain also decrease the swarming motility: 65-80% with respect to WT.

to test the motility and biofilm formation of C.jejuni delta ppx mutants, the author assessed the motility on 0.4% soft agar at 42C for 24h. motility was quantified by measuring the swarming zone around the stabbed area. the result indicate that deleting the gene ppx in C.jejuni affect the amount of biofilm, therefore its affect the motility. also, ppx/gppa genes play a role in transmission related phenotypes such as motility and biofilm formation in C.jejuni.

the phylogenetic analysis using MEGA-5 showed that C. jejuni PPX2 clustered with E.coli and mycobacterium tuberculosis species. (fig.S1) also HHpred show that gene TSARBOMBA_148 homologues to Mycobacterium tuberculosis with e-value= 8.8e-28 and probable 99.96.

Figure 4. Motility and biofilm formation of C. jejuni ∆ppx mutants. (A) Motility was assessed on 0.4% soft agar at 42 °C for 24 h. (B) Motility was quantified by measuring the swarming zone (diameter in cm) surrounding the stabbed area. Each bar represents the average from 3 independent experiments with duplicate samples. *P ≤ 0.05 **P ≤ 0.001.

"plate were inoculated with bacteria from an overnight LB culture on agar plates and incubated at 30C for 8-10h for swimming assays and 12-16h for swarming assay

'. The result indicate that the mutants ppx in B. Cereus impaired with the flagella motility
