Synergistic production of nitrogen-rich hydrochar and solid biofuels via co-hydrothermal carbonization of microalgae and macroalgae: when nitrogen circularity matters.

This work explores the synergies between N-rich (Chlorella pyrenoidosa) and N-deficient (Undaria pinnatifida) macroalgae for the production of N-containing hydrochar and solid biofuels via co-hydrothermal carbonization (co-HTC). The impact of the feedstock (each alga alone and all possible binary mixtures) was comprehensively assessed under different temperatures (180-260 °C) and times (60-240 min). The synergies between micro and macroalgae governed product distribution, nitrogen transformation pathways, and hydrochar quality, with these effects varying by processing conditions.

The world's largest green tide, caused by Ulva prolifera, in the Yellow Sea negatively affects the social and economic development of China's coastal region. The dissolved organic matter (DOM) released from U. prolifera is a potential threat to the offshore ecological health.

The West Antarctic Peninsula (WAP) is a hotspot of climate warming, evidencing glacier retreat and a decrease in the fast-ice duration. This study provides a > 30-y time-series (1987-2022) on annual and seasonal air temperatures in Potter Cove (Isla 25 de Mayo/King George Island). It investigates the interaction between warming, glacial melt, fast-ice and the underwater conditions (light, salinity, temperature, turbidity) over a period of 10 years along the fjord axis (2010-2019), and for the first time provides a unique continuous underwater irradiance time series over 5 years (2014-2018).

Electronic address:
Macroalgae widely distribute in intertidal zones, one of blue carbon organisms. However, the regulatory mechanisms of tide on the carbon sequestration of macroalgae are still unclear. This study explored the effects of desiccation-rewetting cycles induced by tide on dissolved organic carbon (DOC) release from Ulva pertusa, which is prevalent from high to low tidal zones.

Ocean acidification can significantly affect the physiological performance of macroalgae. While copper (Cu) is an essential element for macroalgae and has been extensively studied, the interactive effects of ocean acidification and Cu on these organisms remain less understood. In this study, we measured the photosynthetic characteristics of Ulva lactuca exposed to varying Cu concentrations at two CO levels (415 ppmv, low concentration; 1000 ppmv, high concentration).
