“…Among many chemicals taking part in industrial processes, biodegradation studies focused extensively on phenolic compounds (Di Gioia et al, 2001;Lee and Chen, 2009). Phenol derivatives and mostly polyphenols occur in natural systems and they were identified and studied as significant constituents of olive oil wastewater (Garcia et al, 2000;Dogruel et al, 2009).…”

“…To avoid overtraining, one tenth of the data from the training set was randomly selected as a separate validation set to monitor the training process; that is, during the training of the network the performance was monitored by predicting the values for the systems in the validation set. When the results for the validation set ceased to improve, the training was stopped [38].…”

“…In the present study there was, relative to the control treatment, no effect of 1% BA (treatment +BA). Toxicity of BA is related to the undissociated form, and, with a pKa of 4.2, the concentrations of undissociated BA in slurry from pigs fed 2% BA would have been ~10 mg kg -1 , which is around the threshold where inhibition has been observed with coliform bacteria and a microalga (Knarreborg et al, 2002;Lee and Chen, 2009). Toxic effects of 1% BA would therefore not be expected, leaving only the effects of pH.…”

Ammonia (NH 3 ) volatilization from intensive livestock production is a threat to natural ecosystems. This study investigated pig diet manipulation by 1% (w/w) benzoic acid (BA) amendment and lowering of dietary electrolyte balance through substituting 1.4% (w/w) CaCO 3 with 2.0% (w/w) CaCl 2 . Urine and feces were collected separately from 24 pigs fed one of four diets (Control, +BA, +CaCl 2 , +BA+CaCl 2 ) in metabolic cages and mixed as slurry. During 103 d of storage, all acidifying diets consistently reduced pH in the slurry by 0.4 to 0.6 units. There was a strong relationship between slurry pH and NH 3 emissions, which were considerably reduced by the three acidifying diets. The +BA diet decreased NH 3 emission by 28%, the +CaCl 2 diet by 37%, and the combined +BA and +CaCl 2 diet by 40%. Acidifying diets had no effect on S cycling or emission of volatile S compounds under the prevailing conditions of restricted S feeding. Methane (CH 4 ) emissions were increased by 73% in diets with CaCl 2 . An initial delay in CH 4 emissions was investigated in a separate experiment with manipulation of pH (5.4, 6.7, or 8.8) and inoculation with adapted pig slurry (0, 4, 11, or 19%), which showed that methanogenic potential, rather than inhibitory effects of the chemical environment, caused the delay. In conclusion, NH 3 emissions from slurry could be reduced by addition of BA to pig diets or by controlling the dietary electrolyte balance, but there was no additive effect of combining the two strategies. However, CH 4 emissions from slurry may increase with acidifying diets.
