A treatment process for municipal, commercial, industrial, and institutional fluids containing one or more substances at a first concentration includes a contactor, an aerator, and a separator. The fluid is mixed with a powdered natural lignocellulosic material (PNLM), a microbial growth inoculum, and at least a portion of the fluid in the contactor to provide a mixture that includes an established, acclimated microbial growth in the fluid. The mixture is introduced to an aerator where physical binding and chemical bonding of at least some of the one or more substances to the PNLM additionally physiological uptake by microbial growth in a biosludge reduces the concentration of at least some of the one or more substances in the fluid discharged from the aerator to a second concentration. The biosludge is separated to recover at least a portion of the PNLM that is recycled to the contactor.

The present invention relates to compositions and methods for the remediation of contaminated solids and liquids. In particular, embodiments of the present invention relate to the bioremediation of solids and liquids by a composition comprising a biocatalyst or mixture of biocatalysts. The present invention also relates to methods for producing the bioremediation compositions and methods for applying the bioremediation compositions to contaminated sites, including treatment, storage, and disposal facilities, as well as various contaminated water sources, such as aquifers and reservoirs.

A method, a system, and a wastewater treatment system includes a biological treatment zone for biologically treating fat, oil and grease by adding a culture of microorganisms for partial biodegradation of the fat, oil and grease and/or breaking down the fat, oil and grease. The wastewater system includes a control system, an air injection and distribution system for improving and controlling the biological treatment process and at least one sensor. The at least one sensor may be configured to obtain sensor data, audio data and/or image data, and the control system may be configured to determine the thickness of a layer of fat, oil and grease on the surface of the biological treatment zone.

The present invention addresses the problem of providing a new microorganism that is useful for efficiently decomposing oils and fats, and a use for said microorganism. According to screening results, a new Yarrowia lipolytica having a high capacity to assimilate free fatty acids was successfully obtained. Efficient decomposition of oils and fats is achieved by causing the Yarrowia lipolytica to act under conditions in which fatty acids that are hydrolysis products of oils or fats are present, or under conditions in which oils or fats are decomposed into fatty acids and glycerol.
