A Comparison of Three Protein Sources Used in Medium-Sized Litopenaeus vannamei: Effects on Growth, Immunity, Intestinal Digestive Enzyme Activity, and Microbiota Structure

Fishes, 2023
The type of protein source in diets has many effects on shrimp. In this study, Litopenaeus vannamei with an initial body weight of 3.68 ± 0.002 g were fed for 8 weeks on three experimental diets (isoproteic: 41.00%; isolipidic: 7.61%) that were ...

Fortification of FeS Clusters Reshapes Anaerobic CO Dehydrogenase into an Air‐Viable Enzyme Through Multilayered Sealing of O2 Tunnels

Angewandte Chemie, Volume 137, Issue 33, August 11, 2025.
Fortification of FeS clusters in Ni─Fe CO dehydrogenase (Carboxydothermus hydrogenoformans) reshapes this anaerobic enzyme into an air‐viable variant through multilayered O2 tunnel sealing. The engineered enzyme retains structural integrity and catalytic efficiency in ambient air, offering a practical solution for industrial CO/CO2 bioconversion ...

Effects of alternate feeding between fish meal and novel protein diets on the intestinal health of juvenile largemouth bass (Micropterus salmoides)

Aquaculture Reports, 2022
To investigate the possibility of completely replacing dietary fish meal with several novel proteins in largemouth bass (Micropterus salmoides), the intestinal health of largemouth bass switched to novel protein diets after being fed with fish meal diet ...

Perspectives for Advancing Biotechnological Succinic Acid Production

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

Careful CO Addition Enhances Autotrophic d‐Lactate Formation With Engineered Acetobacterium woodii

Engineering in Life Sciences, Volume 26, Issue 2, February 2026.
ABSTRACT The acetogen A. woodii efficiently converts CO2 and H2 to acetate. Metabolic engineering enabled the autotrophic production of non‐native products, for example, d‐lactate from CO2 by overexpression of d‐lactate dehydrogenase from Leuconostoc mesenteroides and knockout of the native lactate dehydrogenase. During gas fermentation with acetogens,

A TetR-Family Protein (CAETHG_0459) Activates Transcription From a New Promoter Motif Associated With Essential Genes for Autotrophic Growth in Acetogens

Frontiers in Microbiology, 2019
Acetogens can fix carbon (CO or CO2) into acetyl-CoA via the Wood–Ljungdahl pathway (WLP) that also makes them attractive cell factories for the production of fuels and chemicals from waste feedstocks.

Nutrient Digestibility and Growth Performance of Juvenile Penaeus vannamei Fed Diets Containing the Filamentous Fungus, Paecilomyces variotii, Produced From Corn Ethanol Thin Stillage

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Fungal proteins are emerging ingredients having high potential for use in aquafeeds, yet digestibility and practical inclusion limits remain unclear for marine shrimp. This study evaluated a filamentous fungus (Paecilomyces variotii [PV]) produced from corn ethanol thin stillage as a replacement for salmon by‐product meal (SLM) and poultry by‐product ...
