A composition for remediation of soil and groundwater containing halogenated compounds. The remediation composition includes an elemental iron-based composition, which may include activated carbon capable of absorbing the halogenated compounds with numerous pores impregnated with elemental iron. The remediation composition further includes a first bioremediation material including a blend of one-to-many organisms capable of degrading the halogenated compounds. The remediation composition includes an organic compound or polymeric substance and a second bioremediation material including a blend of one-to-many organisms capable of degrading the organic compound or polymeric substance over time (e.g., 20 to 365 or more days to provide a time release substrate-creating material or platform) into smaller molecules or compounds used by the organisms in the first bioremediation material while degrading the halogenated compounds. The organic compound may be a complex carbohydrate such as food grade starch, chitin, or other complex carbohydrate such as one with low water solubility.

Aspects of the present disclosure are directed to a system for determining in-situ oxidation-reduction potential in a formation having a surface separating the formation from an ambient atmosphere. The system may measure the oxidation-reduction potential in-situ, and thereby provide the most precise measurement of the oxidation-reduction potential. The formation surface may be the interface between the ambient atmosphere and the uppermost layer of the formation. The system may comprise a probe for a penetration into the formation. a reference electrode for placing on the formation surface, and a controller configured to communicate with the probe. The controller may be configured to communicate with the reference electrode, determine the oxidation-reduction potential as a potential difference between the reference electrode and the oxidation-reduction electrode, and communicate with the probe, the oxidation-reduction electrode, the reference electrode or any other device by a wire or wireless or a combination of wire and wireless.

Disclosed are novel bioremediation formulations and inocula for formulation of bioremediation formulations. The formulations of the present disclosure comprise viable microorganisms of the species Paenibacillus xylanexedens, Pseudomonas fluorescens, Bacillus safensis, Streptomyces griseus, Micrococcus luteus, and Bacillus megaterium and can be used to degrade glyphosate residue associated with a substrate contaminated with glyphosate, and thereby remedially treat the substrate. Related methods are also disclosed.

A structure and method for three-dimensional restoration of slope soil in an abandoned ion-absorbed rare earth mining area, belonging to the field of ecological restoration technologies. The structure for three-dimensional restoration of slope soil in an abandoned ion-absorbed rare earth mining area provided by the present invention includes an ecological water-harvesting pond, ecological intercepting ditches, an improved soil layer laid on the surface of a to-be-restored slope region and a soil restoration ecological network disposed on the improved soil layer. The improved soil layer, the ecological water-harvesting pond and the ecological intercepting ditches are each provided with a combined plant synusia system. The restoration structure provided by the present invention can effectively improve an extremely degraded ecological environment of the abandoned ion-absorbed rare earth mining area caused by tailings waste land and restore the degraded or polluted mining area soil and environment caused by mine destruction during rare earth mining.

Provided are a strain ofBeijerinckia fluminensis and an application thereof in arsenic oxidation. The strain is AS-56, and has been deposited in the China Center for Type Culture Collection on 5 Dec. 2019, the deposit number being CCTCC NO: M 20191014. The strain AS-56 of Beijerinckia fluminensis can oxidise As(III) to the less toxic As(V) and can completely oxidize 0.15 g/L of As(III) solution to As(V), greatly reducing arsenic toxicity, and thus having wide prospects for application in environmental remediation.

The present invention discloses a strain of Pseudomonas aeruginosa with monomethylamine degradability and the application thereof. This strain, named Pseudomonas aeruginosa GDUTAN1, was deposited on May 24, 2017 in the China Center for Type Culture Collection in Wuhan University, Wuhan City, Hubei Province with a deposit number of CCTCC NO.: M 2017283. This Pseudomonas aeruginosa GDUTAN1 was Gram-negative and rod-like, and round, green and opaque in the colony morphology, having a diameter of 1-2 mm. The Pseudomonas aeruginosa GDUTAN1 of the present invention can be applied to environmental remediation, degrading monomethylamine in the environment at a high degradation efficiency. When it degrades monomethylamine for 96 h at a substrate concentration of 50-140 mg/L, the degradation efficiency can reach more than 99%.
