Characterization of Phytoene Desaturase Knockout Carotenoid‐Deficient Microalgal Mutants Generated by Cas9‐Ribonucleoprotein Complexes

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Phytoene desaturase (PDS; EC 1.3.5.5) is a key enzyme of the carotenoid biosynthetic pathway, catalyzing the desaturation of phytoene, precursor of all carotenoids. In this study, several PDS‐knockout (PDS‐KO) transformants of the chlorophyte microalga Chlamydomonas reinhardtii were generated using a reverse genetics strategy. Two single guide

Effect of Dietary Astaxanthin on Growth Performance, Feed Utilisation, Body Colouration and Survival in Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Astaxanthin is a potent dietary carotenoid known to enhance growth and pigmentation in fish. This study evaluated the effects of graded dietary astaxanthin supplementation, extracted from Haematococcus pluvialis (0, 25, 50, 75 and 100 mg/kg) on growth performance, feed utilisation, body colouration and survival of Nile tilapia (Oreochromis ...

Network Component Analysis Can Identify Potential Axenisation Strategies Circumventing Antibiotic‐Use for Phototrophic Eukaryotic Microalgae

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Network component analysis of published axenisation methods reveals optimal, antibiotic‐free workflows for phototrophic eukaryotic microalgae. Distinct strategies are identified for diatoms, dinoflagellates, and green algae. Verification using microscopy, sequencing, and cell counting enhances reproducibility.
