The ability of 0.1% Trypticase (BBL) to maximize recovery of frozen Escherichia coli on Violet Red Bile Agar is presented.

Eight commercially available selective media were evaluated by the membrane filter technique. Enterococcosel broth (BBL) consistently gave the best recovery of group D streptococci, particularly of Streptococcus bovis.

This paper describes the fabrication of conjugated polymer nanowires by a three stage process: (i) spin-coating a composite film comprising alternating layers of a conjugated polymer and a sacrificial material, (ii) embedding the film in an epoxy matrix and sectioning it with an ultramicrotome (nanoskiving), and (iii) etching the sacrificial material to reveal nanowires of the conjugated polyme...

The alkylating potential of beta-propiolactone (BPL), beta-butyrolactone (BBL), gamma-butyrolactone, and delta-valerolactone, which can be formed by the in vivo nitrosation of primary amino acids, was investigated kinetically. The nucleophile NBP, 4-(p-nitrobenzyl)pyridine, a trap for alkylating agents, was used as an alkylation substrate. The alkylation reactions were performed under mimicked ...

The Oxoid AnaeroGen system was compared with the BBL GasPak for the production of an anaerobic atmosphere and was evaluated for its ability to support the growth of 135 clinically significant anaerobic bacteria. An anaerobe chamber was used as the "gold standard" for supporting the growth of anaerobes. The AnaeroGen requires no catalyst, produces no hydrogen, requires no water, and reduces prep...

One controversial area in protein folding mechanisms is whether some small, ultra-fast-folding proteins exist in distinct native and denatured state ensembles, separated by an energy barrier, or if there is a continuum of states between native and denatured. In theory, the simplest way of distinguishing between single-state barrierless or "downhill" folding and conventional separate state foldi...

Rapid laboratory diagnosis is critical for treating, managing, and preventing methicillin-resistant Staphylococcus aureus (MRSA) infections. We evaluated and compared the potential for MRSA detection of five chromogenic media, Brilliance MRSA agar (Oxoid), ChromID (bioMérieux), MRSASelect (Bio-Rad), CHROMagar (CHROMagar Microbiology), and BBL-CHROMagar (BD Diagnostics). Media were tested with l...

Motivation exists to develop tobacco cultivars with reduced nicotine content for the purpose of facilitating compliance with expected tobacco product regulations that could mandate the lowering of nicotine levels per se, or the reduction of carcinogenic alkaloid-derived tobacco specific nitrosamines (TSNAs). A berberine bridge enzyme-like (BBL) gene family was recently characterized for N. taba...

Could propane from Alaska’s North Slope reduce energy costs for electric utilities and residential space heating, water heating, and cooking demands? We explored the hypothesis that propane is a viable alternative for fourteen selected communities along the Yukon and Kuskokwim Rivers, coastal Alaska, and Fairbanks. Our analysis forecasts propane and fuel prices at the wholesale and retail level...
