Solid, porous, glass-based substrate for storage and delivery of useful microorganisms are described. Materials include one or more microorganisms lyophilized on the substrate, e.g., in the form of a lyophilized biofilm. The materials can be utilized for long-term storage, transport, and deployment of one or more microorganisms, such as consortium of microorganisms at a remediation site.

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 disclosure provides methods and compositions of matter directed to removing heavy metals, such as lead, from aqueous solutions by bioremediation. The methods use bacteria, which thrive in the presence of heavy metals to precipitate the heavy metals from the aqueous solution. In some embodiments, the bacteria comprise Bacillus licheniformis.

The present invention relates to a bio-assisted treatment of wastewater containing sulphide, phenols and hydrocarbons. Further, the present invention relates to a process for eliminating sulphide and other sulphur compounds including, but not limited to, mercaptans, disulfides, PAHs, phenols and hydrocarbons.

One or more new, or existing, or modified, open bottom bio-remediation reactors R are contained within a commercial, industrial, or municipal waste water aeration treatment facility or tank directly above existing and/or new stand-alone diffusers located on the bottom of the facility or tank. The reactors R increase solubility of air and/or oxygen in water, increase energy efficiency, increase through put of treated waste water, and improve bio-remediation of the waste water. Also, a tube reactor having no packing substrates in a non-tube area is described.

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 present invention discloses a heavy metal treatment composite microbial agent in water and a preparation method thereof, belonging to the field of heavy metal treatment. The microbial agent of the present invention is prepared from the following components in parts by weight: 20-30 parts of Pseudomonas, 15-30 parts of Bacillus, 5-15 parts of Staphylococcus, and 5-15 parts of Pichia pastoris. The microbial agent of the present invention can quickly and efficiently adsorb and remove heavy metal ions, and the removal efficiencies of the microbial agent of the present invention on the cadmium, copper, lead and chromium after 2 d reach 81.0%, 56.5%, 52.0% and 74.0% respectively, wherein the adsorption and removal effects on the cadmium and chromium are most obvious. In addition, the microbial agent of the present invention can effectively improve the removal efficiency of the pollutants in the sewage to be treated, can achieve 80% CODMn removal rate or more, 85% TN removal rate or more, 80% TP removal rate or more, and 80% NH.sub.4.sup.+-N removal rate or more with a small amount, meets the pollutant discharge standards of the sewage treatment plant, and has a good application prospect.
