We describe our experience in developing a discourse-annotated corpus for community-wide use. Working in the framework of Rhetorical Structure Theory, we were able to create a large annotated resource with very high consistency, using a well-defined methodology and protocol. This resource is made publicly available through the Linguistic Data Consortium to enable researchers to develop empirica...

The objective was to determine the effect of inoculum concentration on degradation Diesel 2 by a microbial consortium called BIOT.PD001. For this, five systems were designed (in triplicate), which Contained Davis Minimum Medium, 5% as carbon source, and suspension BIOT.PD001 (9 × 108 cells/mL) in concentrations 2, 4, 6, 8, 10% final volume. monitoring carried out indirectly through bacterial co...

Abstract—In the present study, presence of endosulfan, imidacloprid, carbendazim, in the soil /vegetables/cereals and water samples was observed in agriculture fields of Uttarakhand. In view of biodegradation of these pesticides, 9 bacterial isolates were recovered from the soil samples of the fields which tolerated endosulfan, imidacloprid, carbendazim from 100 to 200 μg/ml. Three bacterial co...

This study was carried out to investigate the ability of microalgae Synechocystis sp. to high molecular weight Polycyclic Aromatic Hydrocarbon pyrene (PYR) and artificial microalgal–bacterial consortium at different concentrations. The consortium consisted of one axenic species Synechocystis sp. and two PYR-degrading bacteria with known complementary degradative capabilities viz. Pseudomonas sp...

Diesel is composed of various toxic compounds that can have a negative influence on the environment including plants, microorganisms, and even groundwater being used for cultivation and human consumption. Diesel oil biodegradation kinetics was investigated using bubble-column reactor and microbial consortium isolated from a hydrocarbons spill site and were assessed<em...

Degradation of rice straw by cooperative microbial activities is at present the most attractive alternative to fuels and provides a basis for biomass conversion. The use of microbial consortia in the biodegradation of lignocelluloses could reduce problems such as incomplete synergistic enzymes, end-product inhibition, and so on. In this study, a cellulolytic microbial consortium was enriched fr...

Removal of long-chain hydrocarbons and n-alkanes from oil-contaminated environments are mere important to reduce the ecological damages, while bio-augmentation is a very promising technology that requires highly efficient microbes. In present study, the efficiency of pure isolates, i.e., Geobacillus thermoparaffinivorans IR2, Geobacillus stearothermophillus IR4 and Bacillus licheniformis MN6 an...

the expansion of a microbial bank for the degradation of polycyclic aromatic hydrocarbons (pahs) is crucial for removal of these persistent pollutants. in this study, five gram-negative, aerobic, non-fermentative bacterial strains (iii-r3, iv-p11, iv-p13, iv-r13, and v-p18) were isolated from the activated sludge of a petrochemical wastewater treatment plant using enrichment pro­ tocol based on...

This presentation reports on recent progress the Linguistic Data Consortium has made in addressing the needs of multiple research communities by collecting, annotating and distributing, simplifying access and developing standards and tools. Specifically, it describes new trends in publication, a sample of recent projects and significant improvements to LDC Online that improve access to LDC data...
