Unveiling the underlying molecular mechanisms of high lutein production efficiency in Chlorella sorokiniana FZU60 under a mixotrophy/photoautotrophy two-stage strategy by transcriptomic, physiological, and biochemical analyses [PDF]

Biotechnology for Biofuels and Bioproducts, 2023
Background Chlorella sorokiniana FZU60 is a promising lutein producing microalga. A mixotrophy/photoautotrophy two-stage strategy can achieve high biomass concentration at stage 1 and high lutein content at stage 2, leading to excellent lutein production

Transcriptome analysis reveals the molecular mechanism of differences in growth between photoautotrophy and heterotrophy in Chlamydomonas reinhardtii [PDF]

Frontiers in Plant Science
BackgroundThe green alga Chlamydomonas reinhardtii can grow photoautotrophically utilizing light and CO2, and heterotrophically utilizing acetate. The physiological and biochemical responses of autotrophy and heterotrophy are different in C. reinhardtii.

Heterotrophy Compared to Photoautotrophy for Growth Characteristics and Pigment Compositions in Batch Cultures of Four Green Microalgae [PDF]

Plants
Four strains of green microalgae (Scenedesmus acutus, Scenedesmus vacuolatus, Chlorella sorokiniana, and Chlamydomonas reinhardtii) were compared to determine growth and pigment composition under photoautotrophic or heterotrophic conditions. Batch growth

Genomic insights into the alphaproteobacterium Georhizobium sp. MAB10 revealed a pathway of Mn(II) oxidation-coupled anoxygenic photoautotrophy: a novel understanding of the biotic process in deep-sea ferromanganese nodule formation [PDF]

mBio
Under light conditions, Mn(II) facilitates the photoautotrophic growth of Georhizobium sp. MAB10, a strain derived from deep-sea ferromanganese nodules, along with the generation of dark Mn oxides (β-MnO2). This study investigated the genetic basis of Mn(

Green microalga Chromochloris zofingiensis conserves substrate uptake pattern but changes their metabolic uses across trophic transition [PDF]

Frontiers in Microbiology
The terrestrial green alga Chromochloris zofingiensis is an emerging model species with potential applications including production of triacylglycerol or astaxanthin. How C. zofingiensis interacts with the diverse substrates during trophic transitions is

Mixotrophy emerges as an optimal strategy in mature waters of the Amazon River plume [PDF]

Communications Biology
Phytoplankton, namely diatoms and cyanobacteria, combine photoautotrophy and the uptake of dissolved organic matter (osmotrophy) for a mixotrophic living.

Photosystem I-independent oxygenic photosynthesis in cyanobacteria

Nature Communications
Oxygenic photosynthesis generates ATP and NADPH via linear electron flow from water to NADP+, a process thought to require photosystem I (PSI) for reductant formation.

Metabolomic Insights into the Adaptations and Biotechnological Potential of Euglena gracilis Under Different Trophic Conditions [PDF]

Plants
Euglena gracilis is a metabolically versatile microalga capable of thriving under photoautotrophic (light, no ethanol), mixotrophic (light with 1% v/v ethanol), and heterotrophic (dark with 1% v/v ethanol) conditions.
