Kineochelins—A New Group of Siderophores From an Antarctic Bacterium

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...

Lasalocid or Rumensin to prevent lactic acidosis in cattle

, 1980
Lasalocid or Rumensin (monensin) protected cattle gorged with grain from lactic acidosis. Both lasalocid and monensin prevented the decrease in rumen and blood pH and increase in rumen and blood lactic acid (0(-) isomer) usually associated with lactic

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 591-605, March/April 2026.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

Arenicolide Family Macrolides Provide a New Therapeutic Lead Combating Multidrug‐Resistant Tuberculosis

Angewandte Chemie, Volume 137, Issue 1, January 2, 2025.
Chemical and genomic studies of the arenicolide family macrolides discovered eight new congeners, assigned the previously undetermined absolute configuration, and identified their type I polyketide biosynthetic pathway. Biological evaluation revealed that arenicolide A inhibits drug‐resistant Mycobacterium tuberculosis (Mtb) as an effective ...
