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 provides a novel method for producing an organic acid efficiently. A method for producing an organic acid from a carbon source in a medium using a filamentous fungus, the method comprising culturing the filamentous fungus in a liquid culture medium, in which the carbon source is comprised and a dissolved oxygen concentration is controlled at 8 ppm or more and 35 ppm or less, to obtain the organic acid.

Provided is a mutant filamentous fungus having improved C4 dicarboxylic acid productivity and a method for producing a C4 dicarboxylic acid using the mutant filamentous fungus. A mutant filamentous fungus having enhanced expression of at least one polypeptide selected from the group consisting of a polypeptide consisting of the amino acid sequence represented by SEQ ID No: 2; a polypeptide consisting of an amino acid sequence having an identity of at least 90% with the amino acid sequence represented by SEQ ID No: 2 and having malic enzyme activity; and a polypeptide consisting of an amino acid sequence having deletion, substitution, addition or insertion of one or more amino acids with respect to the amino acid sequence represented by SEQ ID No: 2 and having malic enzyme activity.

The present invention relates to a process for producing single cell protein, wherein a thermophilic fungus is grown a fermentable carbon-rich feedstock at a high temperature and at an acidic pH. This allows for a cost effective fermentation process that can to be run under non-sterile conditions and without additional cooling requirements. The process can be used to convert by-products or waste from agriculture or food production, or organic fractions of municipal solid waste into valuable single cell protein that can be applied as dietary source of protein or protein supplement in human food or animal feed.

The present disclosure is directed to methods of converting food waste to polymers comprising poly(lactic) acid and an additive and biodegradable products thereof. The methods include providing a feedstock comprising food waste, hydrolyzing the feedstock with an enzyme and fermenting the feedstock with a microbe to produce a mixture, isolating lactic acid from the mixture, converting the lactic acid to poly(lactic) acid, adding, reacting, grafting, and/or cross-linking an additive to the poly(lactic) acid to produce a polymer mixture, and forming the polymer with the polymer mixture.
