Background & Aims: Acrylonitrile is widely used as the main raw material in the production of Acrylonitrile butadiene styrene (ABS). It can be considered as pollutant in ABS process effluent. Since the importance of biological systems to treatment the ABS effluents, this study aimed to identify the dominant microorganisms in biological wastewater treatment plant and to evaluate the pot...
This study investigated the potential of aquatic bacteria for their ability as a biocatalyst to synthesized Fe2O3 nanoparticles using iron precursor, FeCl3. A total of 25 aquatic bacterial strains were isolated in trypticase soy agar plus 10 mM FeCl3 with selective enrichment technique. Among the bacterial strains evaluated, NV06 was the only strain able to synthesize Fe2O3 nanoparticles extrac...
Conn (1942) observed that Alcaligenes faecalis required organic nitrogen, but as observed by Porter (1946) no report was found of a study of nitrogen compounds suitable for continued growth of A. faecalis. It was reported, however, that this organism grew in a medium containing NH4 lactate as a source of nitrogen and carbon (Braun and Cahn-Bronner, 1921), and used NH4NO3, asparagine, cysteine, ...
The range of aromatic compounds that support the growth of Alcaligenes eutrophus has been determined, and the pathways used for the dissimilation of these substrates have been explored, largely by enzymatic analyses. The beta-ketoadipate pathway operates in the dissimilation of benzoate and p-hydroxybenzoate; the genetisate pathway, in the dissimilation of m-hydroxybenzoate; and the meta cleava...
An Alcaligenes species, which was isolated from soil, can utilize abietic acid as its sole carbon source. During growth, the bacterium transforms abietic acid into 5alpha-hydroxyabietic acid (I, R=OH), a product considered to be 7beta-hydroxy-13-isopropyl-8xi-podocarp-13-en-15-oic acid (II, R=H) and a compound, C(20)H(28)O(3), which is believed to be an epoxy-gamma-lactone.
