Four selected azo dyes (acid orange 6, acid orange 7, methyl orange and methyl red) were completely decolourised in the presence of anaerobic granular sludge, while only methyl red was degraded in aerobic conditions using a conventional activated sludge. Additional experiments with culture broth devoid of cells showed that anaerobic decolourisation of azo dyes was performed by extracellular red...

BACKGROUND Role of renin-angiotensin aldosterone system (RAAS) in feline systemic hypertension is poorly understood. OBJECTIVES Examine plasma renin activity (PRA) and plasma aldosterone concentrations (PAC) in normotensive and hypertensive cats with variable renal function and in response to antihypertensive therapy. ANIMALS One hundred and ninety-six cats >9 years from first opinion pract...

BACKGROUND: Azospirillum is effective in biostabilization of nitrogen and Pseudomonas is effective in dissolving soil phosphorus. OBJECTIVES: Current study was conducted to assess effect of different level of nitrogen and biofertilizer on seed yield, its components and protein content. METHODS: This research was carried out via spilt plot fac...

Four new azo-dyes, 3-phenyl azopentane-2,4-dion (LA), 3-(4-nitro phenyl azo)-pentane-2,4-dion (LP), 3-(2-nitro phenyl azo)-pentane-2,4-dion (LO) and 4-(1-acetyle-2-oxo-propyl azo)-benzene sulfonate sodium (LS), were synthesized from, aniline, 4-nitroaniline, 2-nitroaniline and sulfanilic acid with acetylacetone, respectively. Reaction of these new dyes with acetate salts of copper(II), nickel(I...

Crystallizing the cobalt(II) salt of the azo dye Orange G from water was found to give the solvent-separated ion-pair species hexa-aqua-cobalt(II) 7-oxo-8-(2-phenyl-hydrazin-1-ylidene)-7,8-dihydro-naphthalene-1,3-disulfonate tetra-hydrate, [Co(H(2)O)(6)](C(16)H(10)N(2)O(7)S(2))·4H(2)O. The asymmetric unit of the cobalt(II) salt contains three independent octa-hedral [Co(OH(2))(6)](2+) cations, ...

The title compound, C26H20N6BrRu(BF4), crystallizes in the centrosymmetric space group P2(1)/n and consists of discrete complex units. The Ru(II) ion is octahedrally coordinated to one 2,2':6',2"-terpyridine (tpy), one 2-(phenylazo)pyridine (azpy) and a Br atom in trans-axial position at a distance of 2.547(5)A. The shorter Ru-N (azo) distance (1.960(3)A) than the Ru-N(py) distance (2.061(3)A) ...

1. The elastase of human spleen was shown to exhibit endopeptidase activity against azocasein and elastin. 2. Activity against several synthetic substrates was detected, and benzyloxycarbonyl-L-alanine 2-naphthyl ester was found to be a good substrate for routine use. 3. The enzyme showed a broad pH optimum in the range of 8.2-9.2 against azo-casein and the synthetic substrate. 4. The effect of...

The photo-rechargeable supercapacitor enables the self-powering of flexible wearable electronics. However, electronics require supercapacitors not only with excellent flexibility but also high energy density. P-diaminoazobenzene (P-Azo) as a new type organic electrode material NN is directly connected to benzene ring and forms large π-conjugated system, which makes it have lower lowest unoccup...
