“…SS increases labile organic substances which stimulate microbial respiration (JorgeMardomingo et al, 2013). In previous reports, soil respiration increased after the application of organic amendments (Jorge-Mardomingo et al, 2013;Mattana et al, 2014), as amendments have a positive short-term effect on soil respiration.

“…It is used to accelerate hydrolysis stage by destructing cells of microorganisms and complex compounds. [11] The most widely used disintegration methods are thermal hydrolysis, ultrasonic irradiation, high-voltage and high-pressure disintegration. [12][13][14][15] Application of mentioned processes before the sludge digestion leads to the increase of VVS destruction from 20% to 30% and the increase of biogas production from 20% to 60%.…”

The anaerobic sludge digestion is a widely used method for sludge stabilization in wastewater treatment plant. This process can be improved by applying the sludge disintegration methods. As the sludge disintegration is not investigated enough, an analysis of how the application of thermal hydrolysis affects the sludge digestion process based on full-scale data was conducted. The results showed that the maximum volatile suspended solids (VSS) destruction reached the value of 65% independently on the application of thermal hydrolysis. The average VSS destruction increased by 14% when thermal hydrolysis was applied. In order to have the maximum VSS reduction and biogas production, it is recommended to keep the maximum defined VSS loading of 5.7 kg VSS/m(3)/d when the thermal hydrolysis is applied and to keep the VSS loading between 2.1-2.4 kg VSS/m(3)/d when the disintegration of sludge is not applied. The application of thermal hydrolysis leads to an approximately 2.5 times higher VSS loading maintenance comparing VSS loading without the disintegration; therefore, digesters with 1.8 times smaller volume is required.

“…Os testes de toxicidade microbiana em solos podem ser rápidos, simples e baratos, além de demandar pequenas amostras de solo (BLAISE, 1991 (TATTI et al, 2012;BROSZAT et al, 2014;KIM et al, 2014;MATTANA et al, 2014;SHAH et al, 2014;SILES et al, 2014).…”

“…Ao contrário das respostas observadas sobre o crescimento (BMC) e metabolismo microbiano (C-CO 2 , DHA e qCO 2 ), a estrutura da comunidade bacteriana nos solos LV e LVA não foi alterada ao longo do tempo (10, 30 e 60 d; (GOMES, et al, 2010;ROUSK et al, 2010;MATTANA et al, 2014). Como consequência das alterações nas condições ambientais, alguns grupos de bactérias e fungos do solo aumentam/diminuem, de acordo com a abundância relativa das substâncias benéficas/tóxicas para os micro-organismos (SILES et al, 2014).…”
