    This study investigated how in vitro gas production (GP) and ruminal fermentation characteristics were affected by increasing concentrations of green algae (C. Reinhardtii) extracts in combination with nanoparticles of MgO and MgS. A solution containing 0.1 M MgCl2 was prepared in 300 mL for the green production of MgCl nanoparticles. The mixture was refluxed for two hours at 85 °C using a reflux condenser after 10 mL of pomegranate algae extract was added. The green algal (C.Reinhardtii), which has many non-toxic antioxidants, was utilized as a carbon source to produce carbon quantum dots (CQD). Rumen fluid used for in vitro experiment was taken from slaughtered calves. The data was analyzed using SAS software in a completely randomized design. The variance analysis results and the average values of the chemical compositions were significantly influenced by the extracts (all P<0.0001). In this line, the values of net gas, pH, organic matter digestibility (OMD), metabolisable energy (ME), and net energy (NE) were found to be the highest for Algae + 50 MgO and the lowest for Algae + 50 MgS, respectively (all P < 0.0001). These promising results imply that extracts from C. Reinhardtii may mitigate the adverse consequences of rumen fermentation. To determine the specific impact of Rhodophyta on greenhouse gas emissions, additional investigation is needed.
