We examined the bioremediation of soils contaminated with munition compounds 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine, and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetraazocine by a procedure that produced anaerobic conditions in promoted biodegradation nitroaromatic contaminants. This consisted flooding 50 mM phosphate buffer, adding starch as supplemental carbon substrate, incubating under static conditions. Aerobic heterotrophs, present naturally soil or added an...
Microwave resonator sensors are attractive for their contactless and label-free capability of monitoring bacterial growth in liquid media. This paper outlines a new microwave biosensor based on pair planar split ring resonators non-invasive solid agar The sensor is comprised two with slightly different resonant frequencies differential operation. transmission coefficient (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> ) the...
This work presents the development of a coplanar waveguide based split ring resonator, integrated with microfluidic channel suitable for liquid sensing applications. The sensor was fabricated via photolithography on 0.5 mm borosilicate glass substrate patterned gold. aligned area and bonded to ensure consistent volume (0.784 μL) over region. microwave 1.5 × 3 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> had resonant frequency...
The effect of peptide charge on the self-assembly, gelation behavior, and model drug release profiles has been explored here for three octa-peptides, VEVKVEVK (VEK2), VKVKVEVK (VEK3), VEVEVKVE (VEK1), that carry a net 0, +2, -2 at neutral pH, respectively. Transparent, self-supporting hydrogels were found to form above critical concentration when modulus was >1 this independent sign charge. TEM, SAXS, shear rheology revealed there no differences in hydrogel structure or mechanical properties...
This letter presents a practical application of differential microstrip microwave sensor for label-free and realtime monitoring Escherichia coli (E. coli) growth under different nutritional conditions on solid agar media. Two planar ring resonators coupled with one-port power divider form the core sensing system. The resonator operates at 1.509 GHz an amplitude -10.21 dB reference 1.798 -11.75 dB. profile E. each glucose concentration in Luria-Bertani (LB) was derived by measuring resonant...
A novel soil treatment method for achieving the removal of dinoseb (2-sec-butyl-4,6-dinitrophenol) from contaminated soils was investigated. One contained as major contaminant, although several other hazardous compounds were also present. second highly with dinoseb. Dinoseb not degraded in these under aerobic conditions at each site. Pretreatment by addition a starchy potato-processing by-product and flooding phosphate buffer stimulated consumption oxygen nitrate soils, thereby lowering...
The metabolism of m -cresol by methanogenic cultures enriched from domestic sewage sludge was investigated. In the initial studies, bromoethanesulfonic acid used to inhibit methane production. This led accumulation 4.0 � 0.8 mol acetate per metabolized. These results suggested that CO 2 incorporation occurred because each molecule contained seven carbon atoms, whereas four molecules product a total eight atoms. To verify this, [ 14 C]bicarbonate added acid-inhibited cultures, and those...
