ANME-2a encoded a protein with a domain specific for PhzF, which is an enzyme involved in phenazine biosynthesis in Pseudomonas fluorescens [152,153].
Cellular viability is determined by the MTS assay, which measures the reduction of {3-(4,5dimethylthiazol-2-yl)-5-(3- carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium} (MTS) in the presence of phenazine methosulfate (PMS).
Cells were incubated with 8% MTS and 0.8% phenazine methosulfate for 1 h at 37[degrees]C and the absorbance of the medium was measured at 595 nm in a Beckman coulter.
A kinetic colorimetric assay procedure is described for measuring lactate dehydrogenase activity, in which the reduction of NAD is coupled to the reduction of tetrazolium salt, 2-p-iodophenyl-3-p-nitrophenyl-5-phenyl tetrazolium chloride (INT), with phenazine methosulfate serving as an immediate electron carrier.
The chemicals used in the experiments were purchased from the following suppliers: acetic acid, dimethyl sulfoxide (DMSO), Dublecco's modified Eagle's medium (DMEM), ethanol, methanol, ethylenediamine tetra acetic acid disodium salt dihydrate (Na2-EDTA), trypan blue, 3-amino-m-dimethylamino-2-methyl phenazine hydrochloride (neutral red), penicillin-streptomycin, sinapic acid, sodium chloride (NaCl), sodium hydroxide (NaOH) from Sigma (St.
To identify the phenazine antibiotics from the selected UPMP3 strain of Pseudomonas aeruginosa and assessment of its antagonistic activity of Ganoderma boninense, three antibiotics phenazine (PHZ), phenazine-l-carboxylic acid (PCA) and pyocyanin (PYO) were extracted from the bacterial fermented broth using benzene and chloroform and detected through High-performance liquid chromatography (HPLC).
Phenazine oxidoreductase (soluble succinate dehydrogenase - SDH) was measured in terms of the decrease in absorbance due to the reduction in 2,6-dichloroindophenol (DCIP) at 600 nm as reference wavelength ([epsilon] = 19.1 [mM.sup.-1] x [cm.sup.-1]) in the presence of phenazine methosulphate (PMS).
Papers in Chapter 3, "Renewable Energy Materials Application, Thermal Materials Engineering, Biomaterials," cover topics of autonomous solar-wind power forecasting systems, biodiesel production from sunflower oil, and phenazine derivatives from Pseudomonas aeruginosa.
The gels were then soaked and equilibrated in a developing buffer (100 mM potassium phosphate pH 7.5 0.1 mM phenazine methosulfate 0.4 mM 3-[45-Dimethylthiazol-2-yl]-25-diphenyletrazolium bromide) after which they were transferred to a fresh buffer containing 1 mM hypoxanthine as a substrate for xanthine dehydrogenase (XD).
