Using NAC Against Antibiotic Resistance Bacteria

GwynneL.

N-acetyl Cysteine Coated Gallium Particles Demonstrate High Potency against Pseudomonas aeruginosa PAO1 SUMMARY: Antibiotic resistant bacterial infections are on the rise, especially in hospitals. One of the culprits is the bacteria Pseudomonas aeruginosa (POA1). Researchers are quickly running out of antibiotics to use against resistant strains. The problem has reached the point where colistin, a… Continue reading Using NAC Against Antibiotic Resistance Bacteria

Impacts of Biogeochemical Redox Processes

GwynneL.

Biogeochemical Redox Processes and their Impact on Contaminant Dynamics SUMMARY: Reduction and oxidation reactions are the drivers behind many biological processes. Energy is both stored and transferred through these reactions. This article talks about the various redox reactions that can occur, both biotically and abiotically, and how that affects both biogeochemical cycles and contaminants. The… Continue reading Impacts of Biogeochemical Redox Processes

Fungal biodegradation and enzymatic modification of lignin

GwynneL.

Fungal biodegradation and enzymatic modification of lignin SUMMARY: This article is a summary breaking down and explaining the different types of ligninases found in white-rot and brown-rot fungi. Each section is a description of a particular type of ligninase and its specific function. LESSON COMMENTS: This is a great article if you’re teaching students about… Continue reading Fungal biodegradation and enzymatic modification of lignin

Silver Dressing and Bacteria

GwynneL.

Wound management in an era of increasing bacterial antibiotic resistance: A role for topical silver treatment(NOT OPEN ACCESS) SUMMARY: One way of fighting antibiotic resistant bacteria is to prevent them from growing in the first place. This article looks at three different types of silver dressing, intended to do just that: silver nitrate, silver sulfadiazine,… Continue reading Silver Dressing and Bacteria

Beaming Pyrimidines Part 2

GwynneL.

Thymine and Other Prebiotic Molecules Produced from the Ultraviolet Photo-Irradiation of Pyrimidine in Simple Astrophysical Ice Analogs(NOT OPEN ACCESS) SUMMARY: In the second edition of beaming pyrimidines, instead of using ammonia, scientists beamed pyrimidines with methanol, water and methanol, methane, and water and methane. As with “Beaming Pyrimidines Part 1”, the gases were cooled way… Continue reading Beaming Pyrimidines Part 2
