Dehalococcoides strains respire a wide variety of chloro-organic compounds and are important for the bioremediation of toxic, persistent, carcinogenic, and ubiquitous ground water pollutants. In order to better understand metabolism and optimize their application, we have developed a pan-genome-scale metabolic network and constraint-based metabolic model of(More)
Tropical agroforestry systems have immense potential to sequester carbon both in aboveground and belowground biomass and soil. Homegarden agroforestry is a popular land-use system in the tropics, sequestrating more organic carbon in soil than crops, monoculture plantations and even than other agroforestry systems. Tree diversity and density are reported to(More)
Moorella thermoacetica is a strictly anaerobic, endospore-forming, and metabolically versatile acetogenic bacterium capable of conserving energy by both autotrophic (acetogenesis) and heterotrophic (homoacetogenesis) modes of metabolism. Its metabolic diversity and the ability to efficiently convert a wide range of compounds, including syngas (CO + H2) into(More)
A study was conducted to investigate the cultural and financial management techniques of betel leaf based agroforestry system practiced in or near homegardens of Khasia community in Jaintapur Upazila in the district of Sylhet, Bangladesh. The Khasia is an educated community where 100% of Khasia people were literate, a stunning fact for this ethnic community(More)
Gene sequences annotated as proteins of unknown or non-specific function and hypothetical proteins account for a large fraction of most genomes. In the strictly anaerobic and organohalide respiring Dehalococcoides mccartyi, this lack of annotation plagues almost half the genome. Using a combination of bioinformatics analyses and genome-wide metabolic(More)
A study was conducted on small-scale enterprises based on murta (Schumannianthus dichotoma (Sal.) Willd.) in Gowainghat upazila (sub-district) to investigate their nature, profitability and sustainability. The study area was selected purposively while a general random sampling method was followed to select individual respondents. About 94% people are(More)
Organohalide respiration, mediated by Dehalococcoides mccartyi, is a useful bioremediation process that transforms ground water pollutants and known human carcinogens such as trichloroethene and vinyl chloride into benign ethenes. Successful application of this process depends on the fundamental understanding of the respiration and metabolism of D.(More)
Mono-ethylene glycol (MEG) is an important petrochemical with widespread use in numerous consumer products. The current industrial MEG-production process relies on non-renewable fossil fuel-based feedstocks, such as petroleum, natural gas, and naphtha; hence, it is useful to explore alternative routes of MEG-synthesis from gases as they might provide a(More)

The agar tree (Aquilaria agallocha Roxb.) is an evergreen tropical tree species containing precious dark resinous heartwood (agarwood). The population of agar tree is rapidly declining in natural forests in Bangladesh, and the species is now being planted in government-owned degraded forest sites as well as privately-owned homestead forests. A survey was(More)
