New Type Biomembrane: Transport and Biodegradation of Reactive Textile Dye

mycolabadmin

Researchers developed an innovative biodegradable membrane containing mushroom fungus (Morchella esculenta) to clean textile dye-contaminated water. The membrane uses natural fungal enzymes called laccase to break down harmful dyes while also absorbing them, achieving 98.6% dye removal in 60 hours. This eco-friendly approach eliminates the need for toxic chemicals used in traditional water treatment and can be reused multiple times, making it promising for industrial textile wastewater treatment.

Beeswax waste improves the mycelial growth, fruiting body yield, and quality of oyster mushrooms (Pleurotus ostreatus)

mycolabadmin

Researchers found that adding beeswax waste to the growing substrate for oyster mushrooms significantly improves their yield and nutritional quality. At optimal levels (5%), mushrooms grown with beeswax waste produced 4% more yield and had 28% more protein than those grown with traditional wheat bran. This discovery offers an environmentally friendly solution for disposing of beeswax waste from beekeeping while producing healthier, more nutritious mushrooms.

Isolation and screening of wood-decaying fungi for lignocellulolytic enzyme production and bioremediation processes

mycolabadmin

Researchers isolated wood-decaying fungi from forests in Latvia to identify species that produce powerful enzymes capable of breaking down complex plant materials. These enzymes have practical applications in cleaning contaminated water, treating textile industry waste, and converting plant biomass into useful products. The study found that certain environmental fungi, particularly Trametes pubescens, produced enzymes at levels exceeding those of commercially used strains, suggesting they could be valuable tools for environmental cleanup and industrial processes.

Hydrothermal liquefaction aqueous phase mycoremediation to increase inorganic nitrogen availability

mycolabadmin

When biomass is converted to biofuel through a heating process called hydrothermal liquefaction, it produces a waste liquid containing nutrients but also toxins. Scientists used a type of fungus called Trametes versicolor to clean up this waste and convert the nitrogen into forms that plants can use. After three days of treatment with the fungus, nitrogen levels that plants can use increased dramatically. Adding helpful bacteria further improved the results, making this waste potentially usable as a fertilizer for growing vegetables hydroponically.

Hydrothermal liquefaction aqueous phase mycoremediation to increase inorganic nitrogen availability

mycolabadmin

This research shows that a common mushroom fungus called Trametes versicolor can clean up wastewater produced during the conversion of food waste into biofuel. The fungus transforms hard-to-use nitrogen compounds in the waste into forms that plants can absorb. After three days of treatment, the nitrogen that plants can use increased dramatically. When bacteria known for converting ammonia to nitrate were added to the fungal treatment, the results improved even more, suggesting this waste could eventually be recycled as a fertilizer for growing plants in water-based farming systems.
