A Novel Adaptation Mechanism Underpinning Algal Colonization of a Nuclear Fuel Storage Pond

open access: yesmBio, 2018
Geochemical analyses alongside molecular techniques were used to characterize the microbial ecology and biogeochemistry of an outdoor spent nuclear fuel storage pond at Sellafield, United Kingdom, that is susceptible to seasonal algal blooms that cause ...

State Estimation of Microalgae Photobioreactors: Applications to Haematococcus Pluvialis

open access: yesChemical Engineering Transactions, 2019
Haematococcus Pluvialis is a type of freshwater green unicellular microalgae that can be used as economical natural source of astaxanthin. To guarantee optimal algae production and the proper conditions for the obtainment of high yield of astaxanthin, the growth process should be carefully monitored and controlled.

Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).

The Effects of Different Light Spectra, UV and Extreme Temperature on the Physiology of Endosymbiotic Jellyfish Cassiopea andromeda

open access: yesMarine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT The endosymbiotic jellyfish Cassiopea andromeda represents a yet untapped marine species that could be targeted as a new source for bioproducts, including food and feed. Also, the potential use of contained valuable ingredients, such as carotenoids and other antioxidants, under controlled aquaculture conditions might be a particularly ...

Growth and development time of subtropical Cladocera Diaphanosoma birgei Korinek, 1981 fed with different microalgal diets

open access: yesBrazilian Journal of Biology
The aim of this work was to investigate the growth performance of Diaphanosoma birgei fed with two Chlorophyceae algae, Ankistrodesmus gracilis and Haematococcus pluvialis using monoalgal diets and simpler mixed diets. D.

Synthetic Biology and Metabolic Engineering of Microalgae for Sustainable Lipid and Terpenoid Production: An Updated Perspective

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1359-1376, March 2026.
ABSTRACT Microalgae are increasingly recognised as powerful platforms for the sustainable production of lipids and terpenoids, with expanding applications in the food, fuel and biomanufacturing industries. In this updated review, we consolidate and critically assess the most recent advances in synthetic biology and metabolic engineering of key ...

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

open access: yesPhysiologia 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)

open access: yesAquaculture, 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 ...

Biolistic Transformation of Haematococcus pluvialis With Constructs Based on the Flanking Sequences of Its Endogenous Alpha Tubulin Gene

open access: yesFrontiers in Microbiology, 2019
Haematococcus pluvialis has high commercial value, yet it displays low development of genetic transformation systems. In this research, the endogenous 5′ and 3′ flanking sequences of the constitutive alpha tubulin (tub) gene were cloned along with its ...

Carotenoid Distribution in Living Cells of Haematococcus pluvialis (Chlorophyceae)

open access: yesPLoS ONE, 2011
Haematococcus pluvialis is a freshwater unicellular green microalga belonging to the class Chlorophyceae and is of commercial interest for its ability to accumulate massive amounts of the red ketocarotenoid astaxanthin (3,3'-dihydroxy-β,β-carotene-4,4'-dione).
