Herein we demonstrate that the mitochondrial genome influences temperature tolerance in Saccharomyces yeasts. The present invention provides methods for manipulating the mitotype of yeast, including methods to produce synthetic yeast hybrids with a selected mitotype and methods to exchange the native mitochondrial DNA (mtDNA) present in polyploid yeast with mtDNA from a desired source. Saccharomyces cerevisiae?Saccharomyces eubayanus hybrids with selected mitotypes are also provided. The yeast and methods of the present invention may be utilized in a variety of applications, including in fermentation to produce beer and wine.

A novel method of growing fungi is disclosed which uses an engineered artificial media and produces high density filamentous fungi biomats that can be harvested with a minimum of processing and from which fungal products such as antibiotics, proteins, and lipids can be isolated, the method resulting in lowered fungus cultivation costs for energy usage, oxygenation, water usage and waste stream production.

The present invention discloses an endophytic fungal strain Pseudophialophora sp. P-B313 and an application thereof, and belongs to the technical filed of microbial applications. The deposit number of the endophytic fungal strain P-B313 is CCTCC M 2021504, and the scientific name thereof is Pseudophialophora sp. The endophytic fungal strain P-B313 can enhance the resistance of rice against seedling leaf blast with a control efficiency of 87.56% and a disease index reduced by 62.59. The biological control efficiency of the endophytic fungus P-B313 against seedling leaf blast in rice has great value by promotion and applications thereof in the field of agriculture.

A fungus having manganese oxidation capacity is provided. The fungus can oxidize Mn.sup.2+ in a water body into a water-insoluble manganese oxide; and the Mn.sup.2+ oxidizing fungus is Cladosporium sp. XM01 strain with the accession number of CGMCC NO. 21083. The Cladosporium sp. XM01 strain is used to oxidize Mn.sup.2+ in a natural water body, and has stable operation within a range of room temperature (15-30 C.) and a range of neutral pH (6.0-7.5) and high Mn.sup.2+ oxidation efficiency; moreover, the XM01 strain may oxidize Mn.sup.2+ cyclically, thereby achieving the in-situ remediation of water bodies or soils polluted by heavy metals or trace organic substances. The manganese oxides generated through oxidization in the growth process of the strain have a good application potential in sewage treatment, water environment restoration, soils and other fields.

A novel method of growing fungi is disclosed which uses an engineered artificial media and produces high density filamentous fungi biomats that can be harvested with a minimum of processing and from which fungal products such as antibiotics, proteins, and lipids can be isolated, the method resulting in lowered fungus cultivation costs for energy usage, oxygenation, water usage and waste stream production.

The present application relates to the technical field of biology, in particular to a Beauveria bassiana strain with high ultraviolet radiation resistance as well as a directional mutagenesis method therefor and use thereof. The Beauveria bassiana strain with high ultraviolet radiation resistance of the present application has an accession number of CGMCC No.22466, and is deposited on Jul. 5, 2021. The strain is obtained by means of taking Beauveria bassiana wild strain CGMCC No.13566 as an original strain and performing multiple rounds of repeated stress and directional screening under simulated sunlight UVB sub-lethal radiation, and has high resistance to ultraviolet radiation. A fungal insecticide prepared by adopting the strain can be well applied to pest green prevention and control in all weather.

This application relates generally to aerial mycelium and methods of making aerial mycelium suitable for use as a food or textile product or ingredient.
