Dietary Feeding Lycopene, Citric Acid, and Chlorella Alleviated the Neurotoxicity of Polyethylene Microplastics in African Catfish (Clarias gariepinus)

open access: yesFrontiers in Environmental Science, 2022
A few studies assessed how natural products can protect fish from the neurotoxic effects of Microplastics (MPs). Therefore, the goal of this study was to look into the neurotoxicity of PE-MPs on the brain tissue of African catfish (C.

A separation of the reactions in photosynthesis by means of intermittent light [PDF]

open access: yes, 1932
Experiments on photosynthesis in intermittent light have been made on two occasions. Brown and Escombe, in 1905, made use of a rotating sector to study the effect of light intensity on the photosynthesis of leaves.

METABOLIC CONDITIONS IN CHLORELLA [PDF]

open access: yesJournal of General Physiology, 1948
1. The effect of nitrate reduction and assimilation on the CO2/O2 quotient of gas exchange has been used as an index of the relative rates of carbon and nitrogen assimilation in Chlorella pyrenoidosa. Changes in over-all metabolism induced by starvation, high light intensity, and nitrogen deficiency have been studied in comparison with the metabolism ...

Chlorella nana sp. nov. (Chlorophyceae): a New Marine Chlorella

open access: yesBotanica Marina, 1978
Chlorella nana sp. nov. (Chlorophyceae) from the Northern Adriatic Sea (about 8 km off Venice) is described, using both light and electron-microscopical techniques. Its prominent feature is the very reduced size (1.5-3μ). Moreover it has an either thick or thin cell wall, a parietal, cup-shaped chloroplast without pyrenoid.
