Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

open access: yesWater and Environment Journal, Volume 40, Issue 3, Page 484-494, August 2026.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...

Trylons: Polyamide Surrogate Substrates Enable High‐Throughput Screening of Nylon‐Degrading Enzymes

open access: yesChemBioChem, Volume 27, Issue 13, 14 July 2026.
The NylCs are nylon hydrolases currently at the forefront of research investigating biocatalysts for nylon degradation. Protein engineering of NylCs has been limited by the inefficiency of activity assays for the evaluation of large mutant libraries.

Inhibition of yeast sporulation by ethidium bromide

Molecular Genetics and Genomics, 1978
Ethidium bromide blocks ascus formation in the yeast Saccharomyces cerevisiae. This may mean that the presence of the mitochondrial genome is required for sporulation in this organism.

Interaction of Ethidium Bromide with Heparin

International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1975
The reactions of hydrated electrons produced during pulse radiolysis have been utilized to investigate the binding of ethidium bromide to heparin. Complexes of ethidium bromide and heparin can be dissociated with salt. Divalent cations are more effective than monovalent cations in this respect.

A synthesis of labeled ethidium bromide

Archives of Biochemistry and Biophysics, 1974
Abstract A method is described for the synthesis of labeled ethidium (3,8-diamino-5-ethyl-6-phenyl phenanthridinium) bromide. Based on benzoic acid, the radioactive precursor used, the yield is 15% of a compound that is indistinguishable from authentic ethidium bromide in its absorption spectra (uv, visible, ir), Chromatographie behavior, and ...

Mitochondrial membranes and mutagenesis by ethidium bromide

Journal of Supramolecular Structure, 1972
AbstractThe conversion of wild type (ρ+) to cytoplasmic petites (ρ−) in Saccharomyces cerevisiae, à mutation in mitochondrial DNA, can be brought about with high efficiency by low concentrations of ethidium bromide (EB). The rate and extent of mutagenesis and its expression can be influenced, and even reversed, by a number of genetic lesions, agents or

Destruction of Ethidium Bromide in Solution by Ozonolysis

Biological Chemistry Hoppe-Seyler, 1988
Ethidium bromide can be rapidly destroyed in aqueous solutions or in isoamyl alcohol by ozonolysis in the presence of H2O2 to give a mixture of organic acids. In a variety of buffers commonly used in recombinant DNA technology destruction of ethidium bromide was more than 99.9%. The yellow reaction mixture after ozonolysis was shown to be nonmutagenic.
