The present invention relates to processes from producing synthetic fuels from biolipid sources by treating the biolipids with biologically produced hydrogen gas, and the fuel stocks and fuels produced thereby.
摘要:
The microorganism-containing biocatalysts disclosed have a large population of the microorganisms irreversibly retained in the interior of the biocatalysts. The biocatalysts possess a surprisingly stable population of microorganisms and have an essential absence of debris generation from metabolic activity of the microorganisms. The biocatalysts are composed of highly hydrophilic polymer and have an internal, open, porous structure that promotes community phenotypic changes.

La presente invención se refiere al uso de cepas de Botrytís cinérea, sus esporas, hifas, micelio, esclerocios, moléculas intra y/o extracelulares de naturaleza orgánica, tales como proteínas, ácidos nucleicos, polisacáridos, lípidos y metabolitos secundarios para la biosíntesis de nanopartículas de oro (AuNps). En términos generales, la presente invención está dirigida a utilizar cepas de B. cinérea y/o moléculas generadas por este organismo para la síntesis biológica de AuNps, siendo entonces el campo de aplicación, la síntesis de nanomateriales, específicamente AuNps utilizando el hongo fitopatógeno B. cinérea y/o sus proteínas intra o extracelulares purificadas en forma individual o combinación de ellas o cualquier otra molécula intra y/o extracelular producida por este organismo como sistema biológico de síntesis. Las nanopartículas metálicas se utilizan en diversas aplicaciones incluyendo: semiconductores, fotoluminiscencia, biomedicina, imágenes para el diagnóstico médico, catalizadores (dispersados y soportados) y en terapias contra algunos tipos de neoplasias (cáncer), entre otras.
摘要:
Methods of dispersing an activation agent, nutrient, or both to a carbonaceous material to stimulate production of a biogenic gas are described. The methods may include accessing a subterranean geologic formation containing the carbonaceous material, and supplying a mixture to the formation. The mixture may include an activation agent or nutrient mixed with a dispersed phase and a continuous phase. The method may also include contacting the carbonaceous material with the mixture, and distributing at least a portion of the activation agent or nutrient over and/or into the carbonaceous material from the dispersed phase. The production of biogenic gases is increased by microorganisms that are stimulated by the distributed activation agent or nutrient to convert a portion of the carbonaceous material into the biogenic gases.
摘要:
A method, process, apparatus, use and formulation for dual biocatalytic conversion of CO 2 containing gas into carbon containing bio-products by enzymatic hydration of CO 2 into bicarbonate ions in the presence of carbonic anhydrase and metabolic conversion of the bicarbonate ions into carbon containing bio-products in a biological culture. The dual biocatalytic conversion may be relatively constant with controlling a feeding of the bicarbonate ions to the biological culture in accordance with demands of the biological culture by retaining over-production of bicarbonate ions and feeding part of the over-production to the biological culture in accordance with nutrient demands of the biological culture. Bicarbonate ions may also be reconverted to generate a pure CO 2 gas stream. The CO 2 containing gas may be derived from operations of a power plant which receives a carbon-containing fuel for combustion, and the biological culture may be an algae culture.

인체에 무해하고 환경오염을 일으키지 않고 토양의 강도와 바람에 대한 저항력이 충분하게 확보된 미생물을 이용한 바이오 결합제로 보강된 토양의 제조방법 및 그에 의해 제조된 토양을 제시한다. 그 방법 및 토양은 실리카와 알루미나를 주성분으로 하는 모래와 우레아(urea)를 생산하는 미생물, 요소(urea), 칼슘 이온 및 고분자 섬유를 결합시켜 제조하며, 이때, 고분자 섬유는 모래에 대하여 0.05wt%~5wt%의 함량을 갖는다. 또한 미생물은 표준 상태에서 1~7×10 -9 (g CaCO 3 ppt cell -1 hr -1 )의 CaCO 3 생성율을 제공하는 것이 바람직하다.
摘要:
The present invention relates to newly discovered, novel strains of thermophilic Geobacillus bacteria isolated from the Northam Platinum Mine (NPM) in South Africa. The present invention further relates to the isolation and characterization of novel thermostable enzymes responsible for the bioreduction of Pt (IV) to elemental Pt. The present invention also extends to the use of the isolated enzymes in the bioreduction of Pt (IV) to elemental Pt and in the microbial transformation of Pt (IV) to platinum nanoparticles. The invention further extends to a process for the bioremediation, or at least partial remediation, of a site contaminated with a source of Pt (IV).
