Ectophoma salviniae sp. nov., Neottiosporina mihintaleensis sp. nov. and four other endophytes associated with aquatic plants from Sri Lanka and their extracellular enzymatic potential

mycolabadmin

Researchers in Sri Lanka discovered six species of fungi living inside freshwater aquatic plants, including two entirely new species. These fungi were identified using advanced genetic testing and were found to produce useful enzymes like amylase, cellulase, and laccase. This research reveals that Sri Lankan freshwater ecosystems harbor diverse fungal communities with potential biotechnological applications.

Strains of Aureobasidium pullulans from Extreme Environments: New Potential Biocontrol Agents?

mycolabadmin

Researchers studied yeast strains collected from extreme environments like deserts and cold coastlines to find natural solutions for protecting fruit crops. They found that Aureobasidium pullulans, a black yeast that thrives in harsh conditions, can effectively control brown rot disease on peaches. The strains showed remarkable ability to survive extreme temperatures and pH levels, making them promising candidates for environmentally friendly crop protection that could help agriculture adapt to climate change.

Acid Phosphatase Produced by Trichoderma harzianum in Solid Fermentation Using Millet

mycolabadmin

Researchers used a fungus called Trichoderma harzianum grown on millet grain to produce phosphatase enzymes, which help convert unavailable phosphorus in soil into forms that plants can use. By carefully controlling the amount of millet, moisture, and fungal starter culture, they achieved significantly higher enzyme production than previous methods. This inexpensive, sustainable approach could improve soil fertility and plant growth in agriculture.

Morphological Engineering of Filamentous Fungi: Research Progress and Perspectives

mycolabadmin

Filamentous fungi are microscopic organisms used to produce important enzymes and chemicals in industries. However, their growth forms during fermentation vary significantly and affect product quality. Scientists are developing methods to control how these fungi grow, both by adjusting fermentation conditions like temperature and oxygen levels, and by using genetic engineering to modify their growth patterns. These approaches help improve industrial production of medicines, enzymes, and other useful compounds.

Enhanced extracellular production of laccase in Coprinopsis cinerea by silencing chitinase gene

mycolabadmin

Scientists improved the production of laccase, an enzyme with industrial uses in detoxification and food processing, by genetically engineering mushroom cells to have stronger cell walls. By reducing the activity of genes that break down chitin in the cell wall, they created mushroom strains that could better withstand the stirring forces during fermentation, resulting in over twice as much enzyme production. This breakthrough could lead to cheaper, more efficient production of this useful green catalyst on an industrial scale.

PRMT5 promotes cellulase production by regulating the expression of cellulase gene eg2 through histone methylation in Ganoderma lucidum

mycolabadmin

Scientists discovered that a protein called PRMT5 controls how much cellulase enzyme the medicinal mushroom Ganoderma lucidum produces. When PRMT5 activates a specific gene called eg2 through a molecular modification of histone proteins, the mushroom produces more cellulase. This enzyme is valuable for breaking down plant waste into useful sugars for industrial and bioenergy applications. This research could help develop better enzyme-producing strains for industries that need cellulase.

The differences between broad bean koji fermented in laboratory and factory conditions by an efficient Aspergillus oryzae

mycolabadmin

This study compared how two types of A. oryzae fungi ferment broad beans to make koji, a starter ingredient for Chinese broad bean paste. Researchers tested the same fungi in small laboratory batches and large factory batches to see if what works in the lab also works in industry. They found that the factory’s larger scale and different environment actually had a bigger impact on the final product than which specific fungus strain was used, though the PN strain was still efficient overall.

Cunninghamella echinulata DSM1905 biofilm-based L-asparaginase production in pneumatically-driven bioreactors

mycolabadmin

Scientists tested different types of bioreactors to grow a fungus called Cunninghamella echinulata that produces L-asparaginase, an enzyme used to treat leukemia and lymphoma. They found that a special hybrid bioreactor with a mesh scaffold allowed the fungus to form a biofilm, which produced significantly more of the therapeutic enzyme than other reactor types. This discovery could improve the production of cancer-fighting medications.

Statistical methodologies for enhancing lipase production from Aspergillus Niger and using biologically treated cottonseed waste in animal nutrition

mycolabadmin

This study shows how scientists can grow an enzyme called lipase on cottonseed waste using a fungus called Aspergillus niger. The leftover treated material becomes excellent animal feed with high protein and important amino acids. This approach solves two problems at once: producing valuable enzymes for industry while creating nutritious feed for livestock from agricultural waste.

Enhanced extracellular production of laccase in Coprinopsis cinerea by silencing chitinase gene

mycolabadmin

Scientists enhanced the production of laccase, a useful enzyme with industrial applications, in a type of mushroom by silencing specific genes involved in cell wall construction. The modified mushroom strain could withstand stronger mixing forces during fermentation, leading to significantly higher enzyme yields. This genetic engineering approach could help make laccase production more efficient and cost-effective for industrial uses like detoxification and food processing.
