A bacterial consortium capable of sucrose degradation primarily to CH(4) and CO(2) was constructed, with acetate as the key methanogenic precursor. In addition, the effect of agar immobilization on the activity of the consortium was determined. The primary fermentative organism, Escherichia coli, produced acetate, formate, H(2), and CO(2) (known substrates for methanogens), as well as ethanol a...

One of the most significant advances in oral microbiology in recent years is advanced imaging methodologies to reveal the geography of oral biofilms. Although the revolution in bacterial sequencing has left us with an unprecedented abundance of data regarding the diversity and abundance of bacteria in caries and periodontal diseases, detailed information on the organization of dental biofilms i...

Recent advances have led to insights into the structure of the bacterial ribosome, but little is known about the 3D organization of ribosomes in the context of translating polysomes. We employed cryoelectron tomography and a template-matching approach to map 70S ribosomes in vitrified bacterial translation extracts and in lysates of active E. coli spheroplasts. In these preparations, polysomal ...

A bacterial consortium BMP1/SDSC/01 consisting of six isolates was isolated from textile effected soil, sludge, and textile effluent from Hudiara drain near Nishat Mills Limited, Ferozepur Road, Lahore, Pakistan. It was selected because of being capable of degrading and detoxifying red, green, black, and yellow textile dyes. The pH and supplements were optimized to enhance the decolorization ab...

<p>Aphelenchoides besseyi is a seed-borne nematode that causes white-tip disease in rice. Yield losses due to this infection reach 30-50% various countries. This research aimed investigate the effectiveness of consortium rhizobacteria and endophytic bacteria controlling white tip while promoting growth rice seeds infected by A. besseyi. The experiments conducted were bacterial compatibili...

The effect of addition of a microbial consortium (A) with 22 micro-organisms on the large scale (400 m3) bioremediation of municipal waste water contaminated with petroleum hydrocarbons was evaluated. Our results showed that addition of Consortium A was effective in reducing the level of contamination of total petroleum hydrocarbons (TPH) from 1086 mg L-1 to 56 mg L-1after just 21 days and to 1...

The widely distributed water fern Azolla was investigated for use as an amendment in the bioremediation of fuel-contaminated environments. In a field experiment Azolla pinnata as well as Pistia stratiotes and Salvinia molesta were applied to plots containing soil that had been surface-contaminated with diesel fuel (2.4 L m(-2)) and flooded with water. The plants quickly died and bacterial flocs...

Assembling functional bacterial biocontrol consortia is expected to expand the scope and efficiency of agents. Generally, interspecies interactions lead incompatibility events, as bacteria can produce antibacterial compounds and/or assemble contact-dependent killing (CDK) devices. Here, we aimed a consortium comprising Lysobacter enzymogenes OH11 Bacillus safensis ZK-1 for synergistic control f...

Background: Hydrocarbons degradation is principally achieved by microorganisms in natural environments. The extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. Objectives: The aims of the current study was to isolate and identify crude oil degrading bacterium from surface sed...
