“…It might indicate that some other factors (moisture, temperature, pH, aeration, composition of nutrient sources) could be of higher importance for the measured activities than the microorganism counts. This result does not correspond to the results of Miller et al (1996). They found a decrease of potential heterotrophic microbial activity using 14 C-labelled glucose.…”

“…Other factors such as cultivation practices, mode of doi: 10.17221/226/2015-SWR (Piutti et al 2002), and herbicide incorporation into the soil after its application (Talbert & Press 1997), or application of Fenton's reagent (Miller et al 1996) can affect the pendimethalin half-life. The effect of soil moisture and soil temperature was described by Zimdahl and Clark (1984).…”

“…The initial reduction of soil microorganisms after pendimethalin application into soil and stimulation of soil microorganisms 50 and 75 days after pendimethalin application was reported by Nayak et al (1994). The effect of pendimethalin on soil microorganisms and their activity was also studied by Miller et al(1996), Shetty and Magu (1998), and Chikoye et al (2014).…”

Pendimethalin [N-(1-ethylpropyl)-3,4-dimethyl-2, 6-dinitrobenzenamine] is a herbicide used worldwide to control most annual grasses and common weeds in cereals, fruit, and vegetables. Its degradation in Haplic Chernozem under controlled greenhouse conditions was studied in this paper. The effect of recommended and doubled pendimethalin doses, as well as the effect of the biopreparate EM-EKO ProBio Plus on pendimethalin degradation in soil and on soil microorganisms was investigated. Pendimethalin half-life ranged from 24.4 to 34.4 days and the double dose did not increase the pendimethalin half-life. Thirty-eight days after pendimethalin application there was no statistical difference between the pendimethalin concentration in soil when applied at the recommended and doubled dose. No effect of pendimethalin on the amount or the activity of soil microorganisms was observed. The effect of EM-EKO ProBio Plus was apparent only on the first sampling of double-dose pendimethalin, however, this bio-preparate had no significant effect on the half-life of pendimethalin, as observed at the end of the experiment.

“…Increased biomass and decreased diversity were measured [23], although many researchers measured rebound in microbial biomass/activity and decreased cell concentration in case of catalyzed hydrogen peroxide (CHP) [4,[24][25][26]. Slight positive effect was found on the microbial biomass [27][28][29], although others found negative effect of KMnO 4 on the microbial biomass [30][31][32].…”

“…Recently, in a comprehensive review, Neyens & Baeyens [10] indicated that Fenton's oxidation is very effective method in the removal of many hazardous organic pollutants from wastewaters. Fenton's oxidation can also be an effective pre-treatment step by transforming constituents to by-products that are more readily biodegradable and reducing overall toxicity to microorganisms in the downstream biological treatment processes [11]. In the present study, the applicability of Fenton's oxidation for the pre-treatment of pharmaceutical effluents originating from a large scale drug manufacturing plant was tested under laboratory conditions.…”

Due to the wide variety of products produced in a drug manufacturing plant, pharmaceutical industry wastewater is a wastewater that is not amenable to conventional biological treatment. In this study, this wastewater was chemically pretreated using Fenton's reagent, since the initial values of the biokinetic coefficients before Fenton indicated that this wastewater could not be biologically treated. A factorial experimental procedure was designed in order to examine the influence of Fenton's pretreatment on biological oxidation. Although the Fenton oxidation process was not very effective, the overall efficiency mounted up to almost 80% in some cases. The optimum experimental conditions for the oxidation of pharmaceutical wastewater were found to be the following: FeSO 4 ·7H 2 O concentration 2 g·L -1 , H 2 O 2 concentration 2 mL·L -1 . It was proved that after the Fenton process, the substrate was rendered significantly more biodegradable since the maximum specific uptake rate K max was increased from 1,76 to 3,14 gCOD·gVSS -1 ·d -1 , whereas the inhibitory coefficient K s was decreased from 3752 to 732 mg·L -1 . Conclusively, Fenton oxidation could be a feasible method for the pretreatment of pharmaceutical wastewater.
