Bioequivalent chemical steam sterilization indicators.

Abstract

Biological indicators used to monitor steam sterilization cycles have two major shortcomings--the incubation period needed to determine if sterilization was accomplished, and the reliance on test packs for gathering information in each load. Chemical indicators do not suffer from these shortcomings. Chemical indicators can respond to time, temperature, and steam parameters to thus parallel the BI reaction. Nine commercially available chemical indicators and four biological indicators were evaluated under the conditions of dry heat, in a biological indicator-evaluator resistometer vessel, and in a hospital sterilizer. The results indicate that wider use of integrated chemical steam sterilization indicators is recommended.

The denatured state under native conditions: a non-native-like collapsed state of N-PGK.

The guanidinium-denatured state of the N-domain of phosphoglycerate kinase (PGK) has been characterized using solution NMR. Rather than behaving as a homogenous ensemble of random coils, chemical shift changes for the majority of backbone amide resonances indicate that the denatured ensemble undergoes two definable equilibrium transitions upon titration with guanidinium, in addition to the major refolding event. (13)C and (15)N chemical shift changes indicate that both intermediary states have distinct helical character. At denaturant concentrations immediately above the mid-point of unfolding, size-exclusion chromatography shows N-PGK to have a compact, denatured form, suggesting that it forms a helical molten globule. Within this globule, the helices extend into some regions that become beta strands in the native state. This predisposition of the denatured state to extensive non-native-like conformation, illustrates that, rather than directing folding, conformational pre-organization in the denatured state can compete with the normal folding direction. The corresponding reduction in control of the direction of folding as proteins become larger, could thus constitute a restriction on the size of protein domains.

Does incineration turn infectious waste aseptic?

Incineration of infectious waste is considered to be biologically safe. We performed basic experiments to confirm that bacillus spores are killed by incineration in a muffle furnace. Biological samples containing 10(6) spores of Bacillus stearothermophilus were placed in stainless steel Petri dishes and then into hot furnaces. The furnace temperature and duration of incineration were 300 degrees C for 15 min, 300 degrees C for 30 min, 500 degrees C for 15 min, 500 degrees C for 30 min and 1100 degrees C for 3 min. We confirmed that all spores of B. stearothermophilus were killed at each of these settings. The effect of incineration seems to be equivalent to that of sterilization, based on the satisfactory sterilization assurance level of 10(-6).

Interaction of the E2 and E3 components of the pyruvate dehydrogenase multienzyme complex of Bacillus stearothermophilus. Use of a truncated protein domain in NMR spectroscopy.

A (15)N-labelled peripheral-subunit binding domain (PSBD) of the dihydrolipoyl acetyltransferase (E2p) and the dimer of a solubilized interface domain (E3int) derived from the dihydrolipoyl dehydrogenase (E3) were used to investigate the basis of the interaction of E2p with E3 in the assembly of the pyruvate dehydrogenase multienzyme complex of Bacillus stearothermophilus. Thirteen of the 55 amino acids in the PSBD show significant changes in either or both of the (15)N and (1)H amide chemical shifts when the PSBD forms a 1 : 1 complex with E3int. All of the 13 amino acids reside near the N-terminus of helix I of PSBD or in the loop region between helix II and helix III. (15)N backbone dynamics experiments on PSBD indicate that the structured region extends from Val129 to Ala168, with limited structure present in residues Asn126 to Arg128. The presence of structure in the region before helix I was confirmed by a refinement of the NMR structure of uncomplexed PSBD. Comparison of the crystal structure of the PSBD bound to E3 with the solution structure of uncomplexed PSBD described here indicates that the PSBD undergoes almost no conformational change upon binding to E3. These studies exemplify and validate the novel use of a solubilized, truncated protein domain in overcoming the limitations of high molecular mass on NMR spectroscopy.
