Large amounts of algal beach wracks are accumulating on the shores of the Mar Menor lagoon due to its ecological imbalance. This biomass is collected and discarded in landfills without any added value. In an attempt to valorize this material, semi-solid media including dried algal wracks with or without prior dialysis, wheat straw and mycological malt extract agar (as control) were prepared to cultivate edible mushroom mycelia...

Despite ecological protections, the Mar Menor lagoon in Spain continues to experience eutrophication, leading to uncontrolled proliferation of algae such as Caulerpa prolifera . When it decomposes, it reduces oxygen and creates sludge, causing fish and other aquatic animals to suffocate. Storms and seasonal changes then wash the uprooted algae ashore, generating foul odors and sludge buildup along the lagoon’s banks. In this s...
