Bio-refinery waste utilization for enzyme production using novel penicillium funiculosum MRJ-16 fungal strain

The present invention relates to a method for obtaining a high titer of enzyme mixture comprising cellulases, hemicellulases and β-glucosidases in reutilization of waste water generated during hot water extraction of lignocellulosic biomass or biorefinery waste water using Penicillium funiculosum MRJ-16 mutant strain. The cellulose or lignocellulosic biomass used in the fermentation process is selected from the group consisting of rice straw, wheat straw, corn stover, cotton stalk or a combination thereof. The enzyme mixture obtained by the present process is used for the saccharification of acid pretreated lignocellulosic biomass.

Composition and methods for reducing corn-on-corn yield penalty

Planting corn in one or more consecutive growing seasons in the same fields causes a yield reduction (“corn-on-corn yield penalty”). We developed methods and inoculants comprising Penicillium bilaii, to reduce corn-on-corn yield penalty. The disclosure covers the inoculants and methods for reducing corn-on-corn yield penalty.

Method for direct transformation of exogenous DNA into resting spores of <i>Penicillium amagasakiense</i>
11236362 · 2022-02-01 · ·

The present invention discloses a method for direct transformation of exogenous DNA into resting spores of Penicillium amagasakiense. The method includes three steps of culture of Penicillium amagasakiense and collection of spores, pretreatment of Penicillium amagasakiense spores, and electroporation of Penicillium amagasakiense spores by using HDEN method, to obtain Penicillium amagasakiense spores with introduction of plasmids to be transformed. In the present invention, non-germinated spores are used as a starting material for introduction of an exogenous molecule, and exogenous DNA is introduced into the resting spores of Penicillium amagasakiense by employing the HDEN electrotransformation technique, whereby the complex step of spore germination is omitted, and steps of protoplast preparation or Agrobacterium-mediated transformation in conventional methods etc. are omitted. Moreover, the transformation efficiency is high, and at least an effect of no less than 6000 positive transformants per transformation reaction system can be achieved.

Microbial strains, compositions, and methods for increasing available phosphate for plants

The present invention provides novel phosphate-solubilizing fungal strains, compositions comprising novel phosphate-solubilizing fungal strains, and methods of using novel phosphate-solubilizing fungal strains to increase the availability of phosphate for plant uptake in soil. In some embodiments, one or more of the novel phosphate-solubilizing fungal strains is coated onto a seed.

PHOSPHATE-SOLUBILZING FUNGAL STRAINS

The present disclosure provides novel fungal strains capable of solubilizing phosphate, as well as compositions and methods of using those strains to increase the amount/concentration of soluble phosphate in a medium that comprises insoluble phosphate.

SYNTHETIC ECOLOGIES FOR DRUG DISCOVERY

The present disclosure is directed to composition and methods for use in drug screening methods. The identification of microbial strains producing antibiotics effective against multi-drug resistant bacterial pathogens using microfluidics and co-encapsulation of predator and prey strains permits rapid and multiplexed assessment of new antibiotics for emerging bacterial pathogens including those resistant to multiple existing antibiotics.

NOVEL STRAINS OF PENICILLIUM CAMEMBERTI

The present invention relates to novel strains of Penicillium camemberti and to the use thereof for the preparation of food products, for example of dairy and/or vegetable origin, such as the ripening of soft cheeses having a moldy and/or mixed crust, in particular camembert.

PROCESS FOR SIMULTANEOUS PRODUCTION OF CITRIC ACID AND CELLULOLYTIC ENZYMES

The present invention relates to a process for simultaneous production of citric acid and cellulolytic enzymes. The batch process comprising (i) adding slurry of a pre-treated lignocellulosic biomass or cellulose in a fermentation media; (ii) inoculating 10% (v/v) active liquid seed culture of Penicillium funiculosum MRJ-16 in the fermentation media of step (i); (iii) subjecting the culture of step (ii) to fermentation in an aerated fermenter at a temperature of 28-33° C. for a duration of 96 hours; and (iv) collecting enzyme broth after fermentation of step (iii) to obtain citric acid and cellulolytic enzymes. The batch and fed-batch process of the present invention results in high titer production of citric acid and cellulolytic enzymes in a single step and using single microbial strain.

USE OF PENICILLIUM EHRLICHII IN CONTROLLING PLANT PESTS, AND A CONTROL METHOD

The present disclosure relates to the technical field of plant pests control, in particular to use of Penicillium ehrlichii Z19 in controlling plant pests, and a control method. The Penicillium ehrlichii Z19 has a deposit number of CCTCC NO: M 2021635. The Penicillium ehrlichii Z19 has a desirable insecticidal activity against lepidopteran pests, especially has a 7-day insecticidal effect of not less than 80% on Helicoverpa armigera, Plutella xylostella, Ectropis obliqua, and Spodoptera exigua. In addition, compared with traditional chemical control methods, the method for controlling pests using the Penicillium ehrlichii Z19 in the present disclosure can control the plant pests in a safe, efficient and pollution-free manner. Therefore, the method reduces pollutions to ecological environment, improves quality and safety of agricultural products, and protects human health.
