2. Project objectives restoration monitoring The main objective of the ‘BIOREM’ project is to demonstrate an innovative, integrated methodology for the restoration and biochemical monitoring of degraded soils. remediation In terms of soil remediation, the project will demonstrate that the BIOREM strategy can successfully restore degraded soils, enhancing their physical-chemical properties and biochemical activity, and increasing fertility. monitoring In terms of soil monitoring, the project promises faster and dynamic monitoring of soil conditions.

Implementation actions

5. Action carried out until now:  Soil characterizations  Sampling and characterization of soils immediately after the application of the remediation strategies (T0) B. Implementation actions

6. Innovative diagnostic methodology Soil monitoring Physical-chemical Physical-chemical parameters (e.g. stability of aggregates, total organic carbon, etc.)they change very slowly Biological parameters Biological parameters: Microbial community structure (genomic analysis) Protein expressed by microorganisms (metaproteomic analysis) Biochemical parameters Biochemical parameters: enzyme activities (  -glucosidase activity) Plant monitoring Superoxide dismutase enzyme expression and activity (biomarker of stress conditions for plants) Very sensitive Each soil sample consists of three subsamples collected at 0-20 and 20-40 cm, mixed, homogenised, sieved (2 mm) and stored dried at room temperature until chemical analysis, and stored at -80°C until biological analysis.

7.  decomposition of the organic substances  mineralization and release of nutrients  fertility and productivity of soil  response of the soil to ecological and functional recovery practices after natural or human stresses  monitor the progress of environmental clean up and restoration Microbial biomass quantity and biodiversity Microbial biomass activity: 1) general parameters (ATP, CO2, Dehydrogenase) 2) specific parameters (hydrolitic enzymes) Soil Enzyme activities BIOINDICATORS AT ECOSYSTEM LEVEL Biochemical and microbiological Biochemical and microbiological soil characteristics have been widely proposed as indicators of soil quality They have an effect on:

8. Enzyme activities  -Glucosidase enzymes catalyze the final limiting step of cellulose degradation Carbon cycle Phosphatase enzymes catalyze the hydrolysis of various organic phosphate esters Phosphorus cycle R-O-PO 3 2- + H 2 O R-O-H + HO-PO 3 2- Dheydrogenase enzymes catalyze the oxidation of organic compounds with the removal of two hydrogen atoms that are transferred to the molecule of NAD + R-H 2 + NAD +  NADH + R + H + Indicator of global microbial metabolism

9. Location of Enzymes in Soils Proteins/enzymes that bind to clay minerals and/or humic substances They are more stable to some environmental stresses such as extreme temperature, digestion by proteases, etc., than free enzymes and can persist for extended periods, thereby providing a long- term perspectives in indicating the hystory of the sample and not just a snapshot of the time of sampling -Intracellular enzymes -Extracellular enzymes

10. Function of Humus infiltrationPromotes infiltration of air and water Holds water and nutrients soil physical structureHelps establish and maintain a strong soil physical structure nutrients Provides nutrients (N and P) BuffersBuffers effects of contaminats Entraps enzymesEntraps enzymes Stable Organic Matter -Humus humus is resistant to microbial attack >1000 years old

11. Due to their long persistence in soil, they react and comply with the surrounding physical environment taking also its characteristics Humo-enzyme complexes could represent a reserve of biochemical energy and nutrients capable to reactivate the ecosystem functionality even in heavy stressed situations, thus representing the necessary conditions for soil resilience Since they have been found in a great variety of natural soils or biologically and physically degraded soils, it may be supposed that they represent a sort of biological barrier before final and irreversible soil degradation Humic-enzyme complexes
