The aim of this study was to characterize the biological stability and maturity degree of compost during a controlled pile-composting trial of mixed vegetable residues （VR） collected from markets of Tunis City with residues of Posidonia oceanica （PoR）, collected from Tunis beaches. The accumulation in beaches （as well as their removal） constitutes a serious environmental problem in all mediterranean countries particularly in Tunisia. Aerobic-thermophilic composting is the most reasonable way to profit highly-valuable content of organic matter in these wastes for agricultural purposes. The physical, chemical, and biological parameters were monitored during composting over 150 d. The most appropriate parameters were selected to establish the maturity degree. The main result of this research was the deduction of the following maturity criterion：（a） C/N ratio 〈 15; （b） NH4^＋-N 〈 400 mg/kg; （c） CO2-C 〈 2000 mg CO2-C/kg; （d） dehydrogenase activity 〈 1 mg TPF/g dry matter; （e） germination index （GI）〉 80%. These five parameters, considered jointly are indicative of a high maturity degree and thus of a high-quality organic amendment which employed in a rational way, may improve soil fertility and soil quality. The mature compost was relatively rich in N （13.0 g/kg）, P （4.74 g/kg） and mgO （15.80 g/kg）. Thus composting definitively constitutes the most optimal option to exploit these wastes.

Autotrophic ammonia-oxidizing bacteria （AOB） have been widely studied in constructed wetlands systems, while mixotrophic AOB have been less thoroughly examined. Heterotrophic bacteria were isolated from wastewater and rhizospheres of macrophytes of constructed wetlands, and then cultivated in a mixotrophic medium containing ammonium and acetic acid. A molecular characterization was accomplished using ITS-PCR amplification, and phylogenetic analysis based on 16S rRNA gene Sequences. Results showed the presence of 35 bacteria, among 400 initially heterotrophic isolates, that were able to remove ammonia. These 35 isolates were classified into 10 genetically different groups based on ITS pattern. Then, a collection of 10 isolates were selected because of their relatively high ammonia removal efficiencies （ARE≥ 80%） and their phylogenetic diversity. In conditions of mixotrophy, these strains were shown to be able to grow （increase of optical density OD660 during incubation with assimilation of nitrogen into cellular biomass） and to oxidize ammonia （important ammonia oxidation efficiencies, AOE between 79% and 87%）. Among these facultative mixotrophic AOB, four isolates were genetically related to Firmicutes （Bacillus and Exiguobacterium）, three isolates were affiliated to Actinobacteria （Arthrobacter） and three other isolates were associated with Proteobacteria （Pseudomonas, Ochrobactrum and Bordetella）.

Background:With the rising global prevalence of fatty liver disease related to metabolic dysfunction,the association of this common liver condition with chronic kidney disease(CKD)has become increasingly *** 2020,the more inclusive term metabolic dysfunction-associated fatty liver disease(mAFLD)was proposed to replace the term non-alcoholic fatty liver disease(NAFLD).The observed association between mAFLD and CKD and our understanding that CKD can be a consequence of underlying metabolic dysfunction support the notion that individuals with mAFLD are at higher risk of having and developing CKD compared with those without ***,to date,there is no appropriate guidance on CKD in individuals with ***,there has been little attention paid to the link between mAFLD and CKD in the Nephrology *** and Results:Using a Delphi-based approach,a multidisciplinary panel of 50 international experts from 26 countries reached a consensus on some of the open research questions regarding the link between mAFLD and ***:This Delphi-based consensus statement provided guidance on the epidemiology,mechanisms,management and treatment of mAFLD and CKD,as well as the relationship between the severity of mAFLD and risk of CKD,which establish a framework for the early prevention and management of these two common and interconnected diseases.
