Morphological and multi-gene phylogenetic analyses reveal Nigrellomyces gen. nov. and one new species in Pleurotheciaceae from China

mycolabadmin

Scientists discovered a new type of fungus in freshwater streams in China called Nigrellomyces aquaticus. This fungus helps break down dead wood in water and is unique compared to other similar fungi because of its distinctive spore structure. The researchers used DNA analysis and detailed observations to confirm this is a completely new genus and species of fungus, adding to our knowledge of freshwater fungal diversity in Southwest China.

Genetic Ablation of the Conidiogenesis Regulator Enhances Mycoprotein Production

mycolabadmin

Researchers created genetically modified versions of a fungus (Fusarium venenatum) used to make mycoprotein, a meat alternative. By removing a gene controlling spore formation, they increased fungal growth by 22%, which could significantly reduce production costs. The modified fungus also contained more amino acids and showed no safety concerns in lab tests, making it a promising advancement for sustainable food production.

A New Species and a New Record of Graphium from Freshwater Environment in Korea

mycolabadmin

Researchers found two types of fungi called Graphium in freshwater streams in Korea. One type (Graphium carbonarium) had been found before in other countries but never in Korea. The other type is completely new to science and was named Graphium aquaticum because it lives in water. This discovery is surprising because scientists previously thought these fungi only lived on wood and were spread by beetles, not in freshwater environments.

Genetic Ablation of the Conidiogenesis Regulator Enhances Mycoprotein Production

mycolabadmin

Scientists created a genetically modified version of the Quorn fungus (Fusarium venenatum) by removing a gene that controls spore production. This modification caused the fungus to grow faster and produce more biomass while also containing higher levels of amino acids. When combined with another genetic modification, the fungus produced 22% more biomass than normal, which could significantly reduce costs for mycoprotein production used in meat alternative products.

Multigene phylogeny and taxonomy of Dendryphion hydei and Torula hydei spp. nov. from herbaceous litter in northern Thailand

mycolabadmin

Scientists discovered and formally named two new fungal species from dead plant material in northern Thailand. Using both traditional microscopy to examine the fungi’s physical structures and modern DNA analysis, they determined these are previously unknown species within the Torulaceae fungal family. The research helps scientists better understand fungal diversity and how different fungal species are related to each other.
