Bioenhancement of Moina cf. macrocopa With Probiotics: Improving Biomass Production and Nutritional Quality in Chlorella‐Based Cultures

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
A critical bottleneck in the growth and survival of freshwater fish larvae is the availability of nutritious live feed. The cladoceran, Moina cf. macrocopa, is suitable for aquaculture due to its high population growth rate and adequate nutritional value.

The influence of probiotic administration on the phagocytic and oxidative burst activity of neutrophils and monocytes in the peripheral blood of dairy cows during different lactation periods

Journal of Veterinary Research
The objective of this bovine peripheral blood study was a comparative assessment of the phagocytic activity of neutrophils and monocytes and of the intracellular killing capacity of neutrophils from cows given no probiotic and from cows which were ...

Single-genotype syntrophy by Rhodopseudomonas palustris is not a strategy to aid redox balance during anaerobic degradation of lignin monomers

Frontiers in Microbiology, 2016
Rhodopseudomonas palustris has emerged as a model microbe for the anaerobic metabolism of p-coumarate, which is an aromatic compound and a primary component of lignin. However, under anaerobic conditions, R.

An Engineered Probiotic Consortium Based on Quorum‐Sensing for Colorectal Cancer Immunotherapy

Advanced Science, Volume 12, Issue 46, December 11, 2025.
This work develops an engineered probiotic consortium sensing pH, hypoxia, and lactate in the tumor microenvironment. It releases a lactate‐depleting enzyme (LdhA) and a PD‐L1 nanobody. In humanized mouse models (MC38 and HT‐29 tumors), it achieves durable oscillations, suppresses tumors, activates CD8+, CD4+, IFN‐γ+ T cells, and reduces Foxp3 ...

Effect of Circular‐Economy‐Derived Experimental Biostimulants on Growth and Development of Soilless Strawberry Plants in Greenhouse Conditions

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Increasing awareness of the adverse effects of agrochemicals is driving farmers to adopt more sustainable strategies for enhancing plant growth. Biostimulants have gained significant attention in both academic research and the horticultural industry as promising tools to promote growth, improve stress tolerance, and enhance crop performance ...

A Role for a Sterol and a Sterol Precursor in the Bacterium Rhodopseudomonas palustris [PDF]

Journal of General Microbiology, 1964
SUMMARY: The multiplication of the purple photosynthetic bacterium Rhodopseudomonas palustris is inhibited by the hypocholesteraemic agents benzmalecene and triparanol. This inhibition is annulled by oleic acid, ergosterol, squalene, farnesol and lanosterol, in that order, but not by mevalonic acid, geranyl acetate, palmitic or stearic acids.

Acclimation strategy of Rhodopseudomonas palustris to high light irradiance

Microbiological Research, 2017
The ability of Rhodopseudomonas palustris cells to rapidly acclimate to high light irradiance is an essential issue when cells are grown under sunlight. The aim of this study was to investigate the photo-acclimation process in Rhodopseudomonas palustris 42OL under different culturing conditions: (i) anaerobic (AnG), (ii) aerobic (AG), and (iii) under ...

Redox Regulation of a Light-Harvesting Antenna Complex in an Anoxygenic Phototroph

mBio, 2019
The purple nonsulfur bacterium Rhodopseudomonas palustris is a model for understanding how a phototrophic organism adapts to changes in light intensity because it produces different light-harvesting (LH) complexes under high light (LH2) and low light ...
