To date, the management of high-strength wastewater represents a serious problem. This work aims to evaluate the performance on chemical pollutants and on sludge production of one of the two full-scale thermophilic membrane bioreactors (ThMBRs) currently operational in Italy, based on monitoring data of the last two and a half years. Removal yields on COD, N-NOx, non-ionic and anionic surfactants (TAS and MBAS), increased with the input load up to 81.9%, 97.6%, 94.7%, and 98.4%, respectively. In the period of stability, a very low value of sludge production (0.052 kgVS kgCOD−1) was observed. Oxygen uptake rate (OUR) tests allowed us to exclude the possibility that mesophilic biomass generally exhibited any acute inhibition following contact with the aqueous residues (ARs), except for substrates that presented high concentrations of perfluoro alkyl substances (PFAS), cyanides and chlorides. In one case, nitrifying activity was partially inhibited by high chlorides and PFAS concentration, while in another the substrate determined a positive effect, stimulating the phenomenon of nitrification. Nitrogen uptake rate (NUR) tests highlighted the feasibility of reusing the organic carbon contained in the substrate as a source in denitrification, obtaining a value comparable with that obtained using the reference solution with methanol. Therefore, respirometric tests proved to be a valid tool to assess the acute effect of AR of ThMBR on the activity of mesophilic biomass in the case of recirculation.

Azotobacter nitrogen-fixing bacteria and urea fertilizer to reduce excessive use of chemical fertilizers. These bacteria can play a role in increasing nitrogen uptake and further growth of soybean plants. This study aimed to obtain growth media for Azotobacter and increase plant and root growth and nitrogen uptake of Biosoy soybean varieties. The research was conducted to help the uptake of n in the soil and reduce the excessive use of chemical fertilizers. The first experiment was carried out by growing bacteria on the media for 120 hours. The second experiment was designed in a completely randomized design that tested two treatments with additional use of urea fertilizer and Azotobacter and no Azotobacter. The results showed that there was no effect of giving Azotobacter from aloe vera gardens, and urea fertilizer showed a significant effect on the observed variables of soil pH in soybean plants on peat soil. In contrast, the variables observed were population, plant height, N content, N-total, plant dry weight, dry weight of plant roots, and N span of soybean plants had no significant effect.
