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

Screening of Chemical Residues and Antimicrobial Resistance in Dehydrated Chicken Feet Intended as Dog Treats: A Pilot Study

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
The pet population is steadily increasing worldwide, and treats, which account for approximately 15% of the pet food market, are the fastest‐growing segment of the pet food industry. However, the widespread use of antimicrobials in poultry farms may pose a direct risk to pets’ health, leading to the emergence of antimicrobial resistance.
