Described herein are methods and compositions that reduce the spread and/or mycotoxin production of Fusarium graminearum. The methods and compositions involve use of one or more of the following endophytes: Alternaria destruens, Fusarium commune, Fusarium oxysporum, or a combination thereof.

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.

The present invention describes a recombinant yeast cell functionally expressing one or more heterologous nucleic acid sequences encoding for ribulose-1,5-phosphate carboxylase/oxygenase (EC4.1.1.39; Rubisco), and optionally one or more molecular chaperones for Rubisco, and one or more phosphoribulokinase (EC2.7.1.19; PRK), wherein the phosphoribulokinase is under control of a promoter (the “PRK promoter”) that enables higher expression under anaerobic conditions than under aerobic conditions.

The purpose of the present invention is to provide an organism having an ergothioneine productivity that is capable of easily producing ergothioneine within a short period of time at a high yield, as compared with a conventional technology, and, therefore, enables ergothioneine production on an industrial scale. This purpose can be achieved by a transformed fungus into which a gene encoding enzyme (1) or genes encoding enzymes (1) and (2) have been inserted and in which the inserted gene(s) are overexpressed. (1) an enzyme catalyzing a reaction of synthesizing hercynyl cysteine sulfoxide from histidine and cysteine in the presence of S-adenosyl methionine, iron (II) and oxygen. (2) An enzyme catalyzing a reaction of synthesizing ergothioneine from hercynyl cysteine sulfoxide using pyridoxal 5′-phosphate as a coenzyme.

A Geomyces mutant strain and an application thereof, relating to the technical field of the screening and application of functional microorganisms; the mutant strain is obtained through a mutagenic method, capable of greatly improving the yield of red pigment; the mutant strain has been preserved in the China Center for Type Culture Collection of Wuhan University on Jan. 24, 2019, and the preservation number is CCTCC NO: M2019086; the mutant strain can be widely used in the field of natural pigment production, can reduce the production cost of red pigment, and has a bright application prospect.

The present disclosure provides a recombinant collagen and a recombinant collagen sponge material. The recombinant collagen comprises: (a) a protein composed of the amino acid sequence represented by SEQ ID NO: 2; and/or (b) a protein which has the same function as (a) and is derived from (a) by substitution, deletion and/or addition of one or more amino acids in SEQ ID NO:2. The recombinant collagen sponge material is obtained by sequential physical cross-linking and chemical cross-linking of the recombinant collagen. The recombinant collagen sponge material according to the present disclosure is capable of hemostasis, wound surface repair, moisture absorption and platelet aggregation, and has high moisture absorption, a significant hemostatic effect and good biocompatibility, assuming great clinical significance in the field of surgery.

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.

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.

The present application relates to methods of producing one or more fatty alcohols and/or one or more fatty aldehydes from one or more unsaturated lipid moieties by combining the obtainment or production of the one or more unsaturated lipid moieties from a biological source with conversion by non-biological means of the one or more unsaturated lipid moieties to one or more fatty alcohols and/or one or more fatty aldehydes. The present application also relates to recombinant microorganisms having a biosynthesis pathway for the production of one or more unsaturated lipid moieties. The one or more fatty alcohols can further be chemically converted to one or more corresponding fatty acetates. The one or more fatty alcohols, one or more fatty aldehydes and/or one or more fatty acetates produced by the methods described herein may be one or more insect pheromones, one or more fragrances, one or more flavoring agents, or one or more polymer intermediates.

The present invention relates to filamentous fungal cells secreting a polypeptide of interest, wherein the expression of a citT gene is altered, reduced or eliminated compared to a non-mutated otherwise isogenic or parent cell, and methods of producing a secreted polypeptide of interest in said cells as well as methods of producing said cells.
