x‐Ray Structure of Streptomyces avermitilis Phospholipase D Reveals a Ca2+‐Stabilized Expanded Active‐Site Cleft Adapted for Phospholipid Binding

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Phospholipase D (PLD) catalyzes the hydrolysis of phospholipids to generate phosphatidic acid and free head groups such as choline. Among bacterial PLD enzymes, Streptomyces chromofuscus PLD (SchPLD), a member of the alkaline phosphatase D (PhoD) superfamily, exhibits unique Ca2+‐dependent phospholipase activity.

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

open access: yesJournal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Extrusion and Pancreatin Superdosing Modulate the Metabolic Impact of 20% Chlorella vulgaris Inclusion in Broiler Diets

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae such as Chlorella vulgaris are gaining attention as sustainable and nutritionally valuable feed ingredients, with the potential to partially replace soybean meal in broiler diets. However, dietary inclusion of 20% C. vulgaris has been attempted, but negatively affected growth performance due to limited digestibility.
