Summary
Antibiotic pollution from sulfamerazine (SM1) and sulfamethoxazole (SMZ) significantly alters drinking water microbial communities, reducing diversity and inducing resistance genes like sul2.
Area of Science:
- Environmental Science
- Microbiology
- Ecotoxicology
Background:
- Antibiotic overuse leads to widespread environmental contamination.
- Sulfamerazine (SM1) and sulfamethoxazole (SMZ) are frequently detected in various environments.
- Understanding their impact on drinking water microbial communities is crucial.
Purpose of the Study:
- To investigate the effects of SM1 and SMZ on the bacterial diversity in drinking water.
- To analyze the changes in microbial community structure and function.
Main Methods:
- Treatment of drinking water samples with SM1 and SMZ at four different concentrations.
- Analysis of microbial community structure using molecular techniques.
- Detection of specific resistance genes.
Main Results:
- Statistically significant changes in microbial community structure were observed.
- Bacterial growth inhibition and reduced microbial diversity in drinking water.
- Induction of the sul2 resistance gene by SM1 was detected.
Conclusions:
- SM1 and SMZ significantly impact drinking water microbial ecology.
- Bacterial community composition may influence antibiotic degradation.
- The induction of resistance genes poses a public health concern.

01:23Amines to Sulfonamides: The Hinsberg Test
4.5K
The Hinsberg test is a method to identify primary, secondary and tertiary amines, named after its pioneer, Oscar Hinsberg. Here, amines are treated with benzenesulfonyl chloride, also known as the Hinsberg reagent, in the presence of an excess of aqueous base, followed by acidification. Based on the nature of the amines, different changes are observed.
Generally, a primary amine reacts with the Hinsberg reagent to produce an N-substituted benzenesulfonamide. The electron-withdrawing sulfonyl...

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Archaea, a domain of single-celled microorganisms, are classified into five major phyla based on genetic and biochemical characteristics: Euryarchaeota, Crenarchaeota, Thaumarchaeota, Korarchaeota, and Nanoarchaeota. Among these, the phylum Euryarchaeota is notable for its remarkable diversity in morphology, metabolism, and ecological adaptations.Morphological and Metabolic DiversityMembers of Euryarchaeota exhibit a variety of cellular shapes, including rods and cocci.

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

Archaea, one of the three domains of life, exhibit remarkable diversity and adaptability, thriving in both extreme and moderate environments. Historically, most identified archaea have been classified into two major phyla: Euryarchaeota and Crenarchaeota. However, recent molecular studies have expanded this classification to include three additional phyla: Thaumarchaeota, Nanoarchaeota, and Korarchaeota, each exhibiting unique characteristics and ecological roles.Thaumarchaeota: Mesophiles...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
