Marine eukaryotic phytoplankton are major contributors to global primary production. To adapt and thrive in the oceans, phytoplankton relies on a variety of light-regulated responses and light-acclimation capacities probably driven by sophisticated photoregulatory mechanisms. A plethora of photoreceptor-like sequences from marine microalgae have been identified in omics approaches. Initial studies have revealed that some algal photoreceptors are similar to those known in plants. In addition, new variants with different spectral tuning and algal-specific light sensors have also been found, changing current views and perspectives on how photoreceptor structure and function have diversified in phototrophs experiencing different environmental conditions.

Hearing loss is one of the most common sensory disorders in humans, and a large number of cases are due to ear cell damage caused by ototoxic drugs including anticancer agents, such as cisplatin. The recent literature reported that hearing loss is promoted by an excessive generation of reactive oxygen species (ROS) in cochlea cells, which causes oxidative stress. Recently, polysaccharides from the cyanobacterium showed many biological activities, including antioxidant activity, suggesting their potential use to combat hearing loss.

Ocean oil spills can severely impact ecosystems and disrupt marine biodiversity and habitats. Microbial remediation is an effective method for removing thin oil slick contamination. In this study, the adsorption and degradation of low-concentration oil spills by Chlorella vulgaris LH-1 immobilized in konjac glucomannan (KGM) aerogel were investigated.

Calcium (Ca)-dependent signalling plays a well-characterised role in the perception and response mechanisms to environmental stimuli in plant cells. In the context of a constantly changing environment, it is fundamental to understand how crop yield and microalgal biomass productivity are affected by external factors. Ca signalling is known to be important in different physiological processes in microalgae but many of these signal transduction pathways still need to be characterised.

is an important source of natural β-carotene (containing and isomers) for industrial production. The phytohormone salicylic acid (SA) has been proven to have impacts on the stress resistance of higher plants, but research on microalgae is currently unclear. In this study, the effects of SA on the growth, biochemical composition, antioxidant enzyme activity, key enzymes of β-carotene synthesis, and cis-and trans-isomers of β-carotene in under different salt concentrations were investigated.

This study evaluated the growth performance of and microalgae cultivated in diluted liquid digestate supplemented with CO, comparing their efficiency to that of a conventional synthetic media. The presence of an initial concentration of ammonium of 125 mg N-NH .L combined with the continuous injection of 1% v/v CO enhanced the optimal growth responses and bioremediation potential for both strains in 200-mL cultures.
