Sizing the Bacillus anthracis PA63 channel with nonelectrolyte poly(ethylene glycols).
Nonelectrolyte polymers of poly(ethylene glycol) (PEG) were used to estimate the diameter of the ion channel formed by the Bacillus anthracis protective antigen 63 (PA(63)). Based on the ability of different molecular weight PEGs to partition into the pore and reduce channel conductance, the pore appears to be narrower than the one formed by Staphylococcus aureus alpha-hemolysin. Numerical inte...
متن کاملMicrobial degradation of polyethylene glycols.
Mono-, di-, tri-, and tetraethylene glycols and polyethylene glycols (PEG) with molecular weight up to 20,000 were degraded by soil microorganisms. A strain of Pseudomonas aeruginosa able to use a PEG of average molecular weight 20,000 was isolated from soil. Washed cells oxidized mono- and tetraethylene glycols, but O2 consumption was not detectable when such cells were incubated for short per...
متن کاملRuling Out Bacillus anthracis
Optimization of methods for ruling out Bacillus anthracis leads to increased yields, faster turnaround times, and a lighter workload. We used 72 environmental non-B. anthracis bacilli to validate methods for ruling out B. anthracis. Most effective were the use of horse blood agar, motility testing after isolates had a 2-h incubation in trypticase soy broth, and screening isolates with a B. anth...
متن کاملLecithinase from Bacillus anthracis.
When Bacillus anthracis is grown in egg yolk medium, a reaction occurs which is presumably due to lecithinase (Colmer, 1948; McGaughey and Chu, 1948; Chu, 1949). In liquid egg yolk medium the lecithinase reaction is characterized by the formation of an opalescent suspension and flocculation of particles which rise to the top of the medium as a curd. A test such as this is usually referred to as...
متن کاملPyrosequencing Bacillus anthracis
Pyrosequencing technology is a sequencing method that screens DNA nucleotide incorporation in real time. A set of coupled enzymatic reactions, together with bioluminescence, detects incorporated nucleotides in the form of light pulses, which produces a profile of characteristic peaks in a pyrogram. We used this technology to identify the warfare agent Bacillus anthracis by sequencing 4 single n...
