Morpho-biometric and biochemical responses in lettuce seedlings treated by different application methods of Chlorella vulgaris extract: foliar spray or root drench?

Ivana Puglisi et al.

Summary: Microalgae-based products applied as biostimulants have attracted the attention of researchers. This study evaluated the effect of two different methods of Chlorella vulgaris extract application (foliar spray and root drenching) on lettuce seedlings. The growth parameters, chlorophyll, carotenoid, and protein contents, as well as enzymatic activities involved in primary and secondary metabolism, were monitored. The results showed that both application methods positively influenced the growth and biochemical response of lettuce seedlings, although their mechanisms of action seemed to be different.

Optimisation of Scenedesmus almeriensis production using pig slurry as the sole nutrient source

Martina Ciardi et al.

Summary: The study demonstrates that pig slurry can be used as an effective nutrient source for biomass production of Scenedesmus almeriensis, with a biomass productivity rate comparable to standard growth medium. Different dilutions of pig slurry did not significantly affect microalgal growth, while ozonation was effective in reducing the chemical oxygen demand concentration of the media.

Microalgae cultivation using palm oil mill effluent as growth medium for lipid production with the effect of CO2supply and light intensity

Prakash Bhuyar et al.

Summary: Malaysia is a major producer and exporter of palm oil, generating millions of tons of palm oil mill effluent (POME) annually. POME, a major environmental pollutant, also contains nutrients and minerals suitable for microbial-based applications like wastewater treatment and biofuel production. Cultivating microalgae in enriched POME has been explored as an effective method to utilize POME and increase biomass yield for applications like biodiesel production.

Cytokinins as central regulators during plant growth and stress response

Si-Min Li et al.

Summary: Cytokinins are a class of phytohormones that regulate plant growth, development, and stress responses by interacting with transcription factors through a series of phosphorylation cascades. They also play a crucial role in crosstalk with other phytohormones to modulate plant development and stress reactions. This review provides a comprehensive overview of cytokinins as central regulators of plant biology and highlights areas for future research.
