“…The results suggested that some azo dyes could serve as a carbon, energy, and nitrogen source for anaerobic bacteria. The potentia] for biotransformation of pyridine in sediments from the Tsengwen River in Taiwan was investigated (Liu and Kuo, 1997). Pyridine was removed in sulfate-amended sediment slurries.…”

MICROBIOLOGY Strain Isolation.A hydrogen-producing anaerobic bacterium, Clostridium butyricum strain SC-E I, was isolated from soybean meal and studied under vacuum and nonvacuum systems. The maximal hydrogen production potential by the bacteria ranged from 1.3 to 2.2 mol Hz/mol glucose, which was less than 50% of theoretical values (Kataoka et aI., 1997). The ability of a sulfate-reducing bacterium, Desulfovibrio desulfuricans, to reduce molybdenum(VI) and molybdenum(IV) in anaerobic environments was investigated (Tucker et aI., 1997). The organism was observed to be useful for removing soluble molybdenum from water. The anaerobic bacterial strain Desulfomonile tiedjei was introduced in soil slurry microcosms supplemented with acetate and formate as cosubstrates and was able to achieve dechlorination of 2.5 mM of 3-chlorobenzoate within 12 days (EI Fantroussi et aI., 1997). A DNA extraction and purification method was also presented. Godon et al. (1997) analyzed the bacterial community structure of a fluidized bed reactor fed by vinasses and established three 16S rDNA clone libraries of Bacteria, Archaea, and Procarya.The enzymes from anaerobic fungi, that is, Piromyces sp. strain E2 and Neocallimastix patricia rum strain N2, effectively converted up to 2% (w/v) microcrystalline cellulose (Avicel) to glucose and surpassed their commercial counterparts (Celluclast and Novozym) in batch degradation of 2% (w/v) Avicel (Dijkerman et aI., ]997). The anaerobic bacterium Dehalospirillum multivorans was applied to a biofilm reactor at 20°C for reduc-518 S.J.W.H.; Stams, A.

This study deals with the optimization of bacterial degradation of pyridine raffinate by previously isolated two aerobic bacteria ITRCEM1 (Bacillus cereus) and ITRCEM2 (Alcaligens faecalis) with accession number DQ4335020 and DQ435021, respectively. The degradation of pyridine raffinate was studied by axenic and mixed bacterial consortium at different nutritional and environmental conditions after the removal of formaldehyde from pyridine raffinate (FPPR). Results revealed that the optimum degradation of pyridine raffinate was observed by mixed bacterial culture in presence of glucose (1% w/v) and peptone (0.2% w/v) at 20% FPPR, pH 7.0, temperature 30°C and 120 rpm at 168 h incubation period . The HPLC analysis of degraded pyridine raffinate samples has indicated the complete removal of a, b and c picoline. Further, the GC-MS analysis of FPPR pyridine raffinate has shown the presence of pyrazine acetonitrile (6.74), 1,3-dioxepin (8.68), 2-pyridine carboxaldehyde (11.26), propiolactone (12.06), 2-butanol (13.10), benzenesulfonic acid (16.22) and 1,4-dimethyl pyperadine while phenol (17.64) and 3,4-dimethyl benzaldehyde as metabolic products of FPPR.
