The present invention relates to 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.

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 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.

Disclosed are a Penicillium oxalicum SDF-25 strain and applications thereof, which relate to the technical field of environmental microorganisms. The Penicillium oxalicum SDF-25 strain has a strain preservation number of CGMCC No. 19272. The Penicillium oxalicum SDF-25 strain can be applied to straw degradation. The Penicillium oxalicum SDF-25 strain provided in the present solution can grow normally at 6 to 37 C. The Penicillium oxalicum SDF-25 strain can secrete a large amount of carboxymethyl cellulase at 10 to 16 C., and still produce enzyme at 6 C. The highest enzymatic activity can reach 993.3 U/mL.
