20090317879 | Use of selection pressures to enable microbial biosynthesis of polyhydroxyalkanoates from anaerobic degradation products - A method for inexpensive and efficient PHA biosynthesis includes operating a sequencing bioreactor in alternating phases of nutrient deprivation and carbon feedstock deprivation to select for robust PHA-producing microbes. Preferably, the bioreactor is operated in a non-sterile manner with mixed cultures of methanotrophs. The method also preferably uses periodic biomass-wasting (PHA harvesting) at the end of the carbon feed phase, gradually lengthening the time period of carbon deprivation phase to create a penalty for rapid PHA degradation and incentive for PHA accumulation. Also, bacterial enrichment cultures may be introduced periodically. The PHA-accumulating bacteria are preferably grown on common anaerobic degradation products, specifically volatile fatty acids, such as acetate and propionate, and methane gas. The PHA has useful applications in bioplastics and other products. | 12-24-2009 |

20120028321 | High Solids Fermentation for Synthesis of Polyhydroxyalkanoates From Gas Substrates - Production of polyhydroxyalkanoates (PHAs) is performed by delivering substrates such as methane in gas phase during a high solids fermentation. Microorganisms are grown under balanced conditions, then gas phase substrates are delivered under unbalanced conditions to produce PHA granules inside the cells. The cells containing these granules are lysed and the bioplastic powder recovered. The balanced phase growth may occur in submerged liquid cultures or attached as biofilms to a surface. | 02-02-2012 |

20130071890 | Production of PHA using Biogas as Feedstock and Power Source - Methods for producing bioplastics from biogas include techniques for the production of PHB using a dirty biogas (e.g., methane from landfill, digester) as both a power source for the process and as feedstock. Biogas is split into two streams, one for energy to drive the process, another as feedstock. Advantageously, the techniques may be implemented off the power grid with no dependence upon agricultural products for feedstock. | 03-21-2013 |
20130180914 | Long-term Sequestration of Uranium in Iron-Rich and Iron-Enriched Sediment - In situ formation of U(VI)-Fe(III) oxides and hydroxides can provide effective uranium remediation. The reason for this is that such compounds can effectively sequester uranium, even in the (VI) oxidation state. Such compounds can be formed in situ by 1) providing Fe(II), 2) reducing uranium to U(IV), and 3) oxidizing the resulting mixture to provide the desired U(VI)-Fe(III) oxides and hydroxides. | 07-18-2013 |
20140076819 | Magnetically Separable Synthetic Nanoparticles for Water Treatment - New multifunctional synthetic nanoparticles are adapted for water treatment, with environmentally-functional layers, optional capping layers, and synthetic antiferromagnetic cores. With high surface-to-volume ratio, these nanoparticles are very efficient in water treatment, including but not restricted to water disinfection, photo-catalytic degradation, contaminant adsorption, etc., in the context of drinking water or waste water treatment. Meanwhile, their magnetic cores are highly magnetically responsive and can be separated by 99% within 10 min using simply a permanent magnet. Moreover, once some non-degradable chemicals (like perfluorinated compounds) are absorbed to the particle surface, these chemicals can be further degraded by introducing hyperthermia or eddy current heating. These particles can be redispersed after the external magnetic field is removed, and can therefore be used in a regenerative treatment process, substantially reducing the cost while eliminating contaminated byproducts. | 03-20-2014 |
