A method for producing mycelia of Paecilomyces saturatus, a bioplastic, and a method for treating wastewater are disclosed. The method for producing mycelia of Paecilomyces saturatus includes steps of: providing a culturing medium containing at least one monosaccharide and at least one inorganic substance; placing spores of Paecilomyces saturatus into the culturing medium; cultivating the spores of Paecilomyces saturatus in an aerobic environment for a predetermined period of time to grow mycelia of Paecilomyces saturatus; and filtering to obtain the mycelia of Paecilomyces saturatus.

The present invention provides a process for the treatment of sewage sludge with enzymes, which process comprises treating a sewage sludge resulting from the treatment of municipal or industrial waste water with a composition comprising a fermentation supernatant product from a Saccharomyces cerevisiae culture and a non-ionic surfactant, wherein said fermentation supernatant product is free of active enzymes, at conditions suitable for generating said active enzymes from said sewage sludge in situ.

The invented bio-electrical system is a housing-electrode which allows insertion of another electrode for various electrochemical and bio-electrical applications. Together with other invented elements as well as standard components, the system is fully scalable, modular, and allows production and collection of gases under pressure. It can be built in many shapes, such as the embodied tubular shape. The design allows operation on unstable ground, for example on ships. Flow of electrolyte can be regulated and directed in cascaded reactions by opening and closing the compartments of the outer or the inner electrodes using the provided electrode holders. The redox conditions inside the system can be controlled using off-the-shelf power supplies which are controlled using the provided algorithm. Gas collection can be regulated based on the level of liquid inside the system using the provided float switches or conductivity probes even as the system is moving or operated under zero-gravity conditions.

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 comprises compositions and methods for enhancing biological processes, such as plant growth or bioremediation. For example, the present invention comprises compositions and methods for effectively remediating chemical and organic wastes and reducing the environmental risk from manure, septic, sewage, oil pollution, and other contaminants.

Metal bioremediation and metal mining strategies can include compositions and methods.

The subject invention provides microbe-based products, as well as their use to improve oil production and refining efficiency by, for example, remediating the disposable layers in oil tanks and other oil storage units. In preferred embodiments, the microbe-based products comprise biochemical-producing yeast and growth by-products thereof, such as, e.g., biosurfactants. The subject invention can be used to remediate rag layer and/or other dissolved solid layers that form in water-oil emulsions. Furthermore, the subject invention can be used for remediating solid impurities, such as sand, scale, rust and clay, in produced water, flow-back, brine, and/or fracking fluids.
