Different bacterial species produce over 100
phenazine derivatives (Gibson et al., 2009) but P.
[F.sub.420] cycling can be accomplished using the [F.sub.420]-dependent hydrogenase (Frh) and [F.sub.420][H.sub.2]:
phenazine oxidoreductase (Fpo) complex [48] (Figure 2).
In spite of the detection of
phenazines from the oil palm rhizospheric strain of P.
They found that the bacterial colonies produced a
phenazine gradient that is likely to be of physiological significance.
Several types of electron mediators considered are as follows: ferrocene, hexacyanoferrate, tetrathiafulvalene, ophenylenediamine, quinones, flavins, quinoic type compounds, such as phenoxazines and organic dyes, including methylene blue (MB), Prussin blue,
phenazines, toluidine blue, methylene green, meldola's blue, and tionin (REZAEI-ZARCHI et al., 2009; YANG et al., 1998).
To improve DNA quality it was used cross-linked polyvinyl pyrrolidone (PVPP) to remove alkaloids, terpenoids, glycosides, phenols,
phenazines polyketides and peptides, as well as protein and carbohydrate (HAAF et al., 1985).

Phenazines aqnd other redox-active antibiotics promote microbial mineral reduction.
aeruginosa invades the mucus, turning it blue-green with antibiotic pigments called
phenazines and even destroying lung tissue,
