“…Li et al reported that reactive oxygen species (ROS) scavengers can markedly increase cellulase production . β-Carotene, a potent antioxidant compound, has been found to reduce the ROS content, , which may be the reason for the higher cellulase activity in the β-carotene-producing MuQ3 than in the parental strain RUT-C30. Pi et al demonstrated that the insertion of the β-carotene synthesis gene and the cellulase synthesis gene into the genome of Rhodotorula glutinis enabled the simultaneous production of both β-carotene and cellulase, turning biomass waste into valuable products and renewable energy.…”

“…Therefore coccoliths per se in the present study might have a very limited contribution to photoprotection. In addition to calcification and coccolith shell, carotenoids often play a role in light harvesting or energy dissipation depending on the light availability (Goss and Lepetit 2015 ; Leverenz et al 2015 ; Xi et al 2022 ), and they were higher in the diploid cells (Fig. 3 ).…”

“…Its functions include assisting in light absorption and protecting chlorophyll molecules from photooxidation by quenching singlet oxygen species. The rise in β-carotene concentration with increased light intensity is a part of the plant's adaptive response to shield the photosynthetic apparatus from potential damage caused by ROS under high light conditions [61]. Additionally, carotenoids, including violaxanthin and β-carotene, play a role in maintaining the structural integrity of photosynthetic complexes [62].…”
