“…Essa diminuição da produção de metano é devida a interferência dos micro e nanoplásticos podem agir diretamente na formação de grânulos, assim como nas membranas celulares devido à sua carga o que pode explicar o porquê de os impactos da produção de metano por nanoplásticos catiônicos de PS (PS-NH 2 ) foram maiores que os nanoplásticos aniônicos de PS (PS-SO 3 H), embora a quantificação e mecanismos de ação dos nanoplásticos ainda necessita ser melhor explorada (Feng et al, 2018). Outro fator tão ou mais importante do que a presença de micro e nanoplásticos são as substâncias que foram adsorvidas nos mesmos e que durante o processo bioquímico se tornam disponíveis no meio, dentre elas pode-se destacar: antibióticos, poluentes orgânicos persistentes (POPs) e metais pesados os quais são comumente encontrados junto de microplásticos e possuem impacto significante na digestão anaeróbia (Luo et al, 2020).…”

“…Solubilization refers to the incipient phase of anaerobic fermentation and is commonly considered as a speed-limiting step [30]. Once the solid releases more dissolved total organic carbon (TOC) into the solution, more bioavailable substrates will be produced.…”

Effects of Lighter Dose of Oxytetracycline on the Accumulation and Degradation of Volatile Fatty Acids in the Process of Thermophilic Anaerobic Digestion of Swine Manure

Oxytetracycline (OTC) is a commonly used antibiotic in livestock farming for controlling intestinal and respiratory infections in farm animals. However, the absorption of antibiotics by animals is limited, and most antibiotics are excreted in the original form with manure, which will have an impact on the environment. The removal of antibiotics from swine manure could generally be performed via anaerobic digestion (AD). In this study, the effect of oxytetracycline (OTC) at doses of 0.1, 0.5, and 1.0 mg/L on the thermophilic anaerobic digestion of swine manure (55 °C) in batch digesters was studied. The methane production, volatile fatty acid (VFA) levels, and dissolved organic matter (DOM) were determined and compared with the control (0 mg/L of OTC). The results indicate that (1) OTC at 0.1 mg/L had no inhibitory effect on methane production or on the accumulation of VFAs, while 0.5 mg/L and 1.0 mg/L inhibited methane production, with inhibition rates of 4.03% and 14.12% (p < 0.05), respectively; (2) the VFAs of each reactor peaked on the first day of the reaction, and as the OTC dose increased from 0 to 1.0 mg/L, the maximum VFA accumulation increased from 1346.94 mg/g to 2370 mg/g of volatile solids (VS); and (3) oxytetracycline (0.5 and 1.0 mg/L) could promote the temporary accumulation of propionic acid, which did, however, not result in significant VFA accumulation. Further, OTC at 1.0 mg/L can promote DOM production, and therefore, VFA accumulation.

“…Other disposal methods are also used, including land application, incineration, and producing building materials (Yang et al 2015). Meanwhile, energy reuses of the waste biomass have been explored, which include anaerobic digestion to biogas or extracting the lipid (Tyagi and Lo 2013;Bora et al 2020;Luo et al 2020). Microalgae are known to have relatively higher lipid content, and also they have the advantage of high growth rate, as well as a high ability to fix carbon dioxide (Shi et al 2018).…”

A new algal-bacterial granular sludge treatment method was used to treat salty eutrophication water. The results indicated that the treatment removed more than 98% of the total inorganic nitrogen and the total phosphorus after a 15 d cultivation period using 2% salinity simulated eutrophication water. For the 4% salinity simulated water, the total phosphorus was not able to be removed and was even higher in the effluent; and the total inorganic nitrogen was only removed 17%. Thus, the algal-bacterial granules were efficient for removing nitrogen and phosphorus in 2% salinity eutrophication water but were not effective for 4% salinity water. High levels of filamentous algae proliferation growing on the surface of the granules was primarily responsible for the good performance in 2% salinity water. However, the lipid accumulation was greatly enhanced (reactor R2 at a 27.6% increase and reactor R4 at a 107% increase) for both granule types due to the algal growth. Thus, treatment of the salty eutrophication water can also greatly increase the added-value of the algal-bacterial granules.
