Co-treatment of H2S and toluene in a biotrickling filter
Biological treatment is an emerging technology for the treatment of publicly owned treatment works (POTWs) off-gases. Most of POTWs off-gases contain H2S and a wide range of volatile organic compounds (VOCs). Since co-treatment of odors and VOCs in biotrickling filters is a relatively unexplored area, the simultaneous biotreatment of H2S and toluene (as the model VOC) was investigated. The expe...
متن کاملA Microscopic Method of Distinguishing Dead from Living Bacterial Cells.
Dilute solutions of dyes were applied to animal or plant cells nearly as far back as a century ago. By this means it was sought to gain an insight into various life processes of the cells, to demonstrate certain cellular structures, or to find out whether the cell were dead or alive. The work started by Ehrlich on nerve cells and blood cells, and the stimulus it gave other workers, have given u...
متن کاملStudies on the Influence of Various Metabolic Uncouplers on the Biodegradation Rate of Toluene in a Biofilm Bio-Filter Reactor
Biological inhibition of air pollution has vast advantages over physicochemical methods. One of the biggest challenges faced by researchers with traditional bio-filter in controlling Volatile Organic Compounds (VOCs) such as Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) is, low degradation rate (elimination capacity) and accumulation of very high biomass. The use of metabolic uncouplers...
متن کاملBacterial species dominance within a binary culture biofilm.
Studies with two species of bacteria, Pseudomonas putida and Hyphomicrobium sp. strain ZV620, were carried out to evaluate the overall net rate of accumulation of biofilm, the biofilm species composition, and individual species shear-related removal rates. Bacterial cells of either or both species were deposited onto glass or biofilm surfaces to initiate multispecies biofilms. Subsequent biofil...
متن کاملCommunity dynamics within a bacterial consortium during growth on toluene under sulfate-reducing conditions.
A sulfate-reducing bacterial consortium was enriched from an anoxic aquifer contaminated with BTEX compounds, using toluene as a growth substrate. Total cell counts, protein contents and sulfide production were determined to follow growth at the in situ temperature (14 degrees C) and at 25 degrees C, respectively. Community members were identified by 16S rRNA gene cloning and sequencing. Phylog...
