As a result, individuals with CGD are particularly vulnerable to infections from catalase-positive bacteria and fungi, as well as experiencing inflammatory complications such as inflammatory bowel ...

Lactic acid bacteria (LAB) have excellent antioxidant properties ... The pure colonies were checked through gram staining and catalase testing. Gram-positive and catalase-negative strains were ...

Catalase, methyl red, Voges–Proskauer, indole production, and oxidation fermentation tests were positive for all strains, while one strain, WumN3, tested negative for the nitrate reduction test; the ...

Oil-degrading bacteria were characterized both morphologically ... including S4 and S7, were negative. The catalase test demonstrated that most isolates were positive, reflecting their ability to ...

Experimental studies involving the manipulation of ROS levels in model organisms have generally shown that interventions ... cytoplasm and extracellular space. Catalase (CAT) works to eradicate ...

Research scientist Bradley Lusk, first author of the study, was curious about what happens to protons in the microenvironments of these bacteria during biodegradation: “If you produce too many ...

Using a new method to study how carbohydrates modify proteins, scientists have discovered that gut bacteria can alter molecular signatures in the brain.

Researchers have succeeded in cultivating an ultra-small bacterial strain parasitizing archaea and classified it as new species and genus of Minisyncoccus archaeiphilus.

This is an important and solid study that examines the role of TFAM, a protein that helps maintain mtDNA, in mtDNA mutator mice. The authors have demonstrated that TFAM's counteractive role in mtDNA ...

Researchers at the VIB-KU Leuven Center for Microbiology and the VIB-KU Leuven Center for Brain & Disease Research have revealed a mechanism involving protein aggregation that allows bacteria to enter ...

This discovery could also have implications in studies of polymer-secreting conglomerations of bacteria known as biofilms—the slippery goo on river rocks, for example—and in industrial ...
