“…It is one of the reason for increasing microbes in soil by Fenton and A-PS treatments. Kakosová et al (2017) indicates utilization of citric acid as a better growth substrate for the more active part of the microbial community. Sutton et al (2011) figured that microorganisms were killed by permanganate oxidation, but the microbial populations were increased following the oxidation.…”

“…In general, the oxidative stress increase in persulfate treatment or decrease in Fenton's reagent with increasing pH, and changes in redox conditions caused by chemical oxidation significantly alter subsurface conditions and are toxic to microbial populations (Kakosová et al, 2017). Although microbial activity can be reduced temporarily by chemical oxidation, the populations of microorganism could recover for contaminant degradation in laboratory experiments (Xu et al, 2016) and in some industrial field (Sutton et al, 2013).…”

Chemical oxidation is a promising pretreatment step coupled with bioremediation for removal of polycyclic aromatic hydrocarbons (PAHs). The effectiveness of Fenton, modified Fenton, potassium permanganate and activated persulfate oxidation treatments on the real contaminated soils collected from a coal gas plant (263.6 ± 73.3 mg kg −1 of the Σ16 PAHs) and a coking plant (385.2 ± 39.6 mg kg −1 of the Σ16 PAHs) were evaluated. Microbial analyses showed only a slight impact on indigenous microbial diversity by Fenton treatment, but showed the inhibition of microbial diversity and delayed population recovery by potassium permanganate reagent. After potassium permanganate treatment, the microorganism mainly existed in the soil was Pseudomonas or Pseudomonadaceae. The results showed that total organic carbon (TOC) content in soil was significantly increased by adding modified Fenton reagent (1.4%-2.3%), while decreased by adding potassium permanganate (0.2%-1%), owing to the nonspecific and different oxidative properties of chemical oxidant. The results also demonstrated that the removal efficiency of total PAHs was ordered: permanganate (90.0%-92.4%) > activated persulfate (81.5%-86.54%) > modified Fenton (81.5%-85.4%) > Fenton (54.1%-60.0%). Furthermore, the PAHs removal efficiency was slightly increased on the 7th day after Fenton and modified Fenton treatments, about 14.6%, and 14.4% respectively, and the PAHs removal efficiency only enhanced 4.1% and 1.3% respectively from 1st to 15th day after potassium permanganate and activated persulfate treatments. The oxidants greatly affect the growth of soil indigenous microbes, which cause further influence for PAHs degradation by bioremediation.

“…Phospholipid fatty acid profiles (PLFA), an indicator of living microbial biomass and rough community structure, were determined according to ISO/TS 29843-2 [32]-a method adopted from Zelles et al [33] used in previous studies [31,[34][35][36][37]. Briefly, total lipids were extracted from the soil by a mixture of methanol, chloroform and phosphate buffer (0.05 mol/L, pH 7, ratio 2:1:0.8) and separated on polar silica SPE columns to fractions of non-polar lipids, glycolipids, and polar lipids.…”

Fertilization is a key factor for sustaining productivity in agroecosystems. A long-term experiment in cambisol following periodical application of several types of fertilization has been running at the experimental site since 1954. In this study, we determined the impact of applied inorganic and/or organic fertilizers on the activity of soil enzymes and on the structure of microorganisms at depths of 0–30 cm and 30–60 cm. Single-factor comparison showed that use of inorganic and/or organic fertilizer had an insignificant effect on the activities of soil enzymes (at depths 0–30 cm and 30–60 cm) and also on the structure of microbial communities at both depths studied. Only soil respirations exhibited stimulation by combined fertilization. The results, irrespective of sampling depth (0–60 cm), showed that application of combined organic and inorganic fertilization stimulated the activity of glucosidases and use of inorganic fertilizer inhibited the activity of arylsulphatases. Respirations were stimulated by application of organic fertilizer and combined fertilization. Nevertheless, principal component analyses, which calculate with multidimensional data, revealed differences in samples treated by sole mineral fertilizer compared to other variants, especially in the lower layer. In general, our results indicate that use of combined fertilization may improve biological characteristics in deeper parts of soil profile and possibly increase biological activity in agroecosystems.

“…The low quality of soil was reflected also in the state of soil microorganisms which play important role in soil functions and plant growth. The soil microbial communities were characterized using phospholipid fatty acids (PLFA), method compliant with ISO/TS 29843-2 [27] used in our recent studies [28,29,30]. Microbial activity was assessed via basal soil respiration as described previously [31].…”

Background: To determine the level of plant stress of second-generation biofuel crop Miscanthus x giganteus ( Mxg ) grown in poor quality post-military soils using physiological parameters; to identify impact of plant growth regulators (PGRs) on the stress reduction and to select the fluorescence indicators most suitable for quantification of stress. Plant fitness was quantified with non-invasive measurement of leaf fluorescence using 16 different indexes. Simultaneously visible stress signs were observed on stems and leaves and differences were revealed by microscopy of leaf sections. Results: Leaf fluorescence analysis, visual observation and changes of leaf anatomy revealed significant stress in all tested subjects . Besides commonly used F v /F m and P.I. (performance index), the fluorescence parameter T fm (time to achieve maximum fluorescence) seems to be rather sensitive and applicable for revealing finer differences. However, none of investigated parameters proved significant positive effect of PGRs on stress reduction. Conclusions: Measuring F v /F m , P.I., and T fm is a suitable method for revealing stress affecting Mxg in poor post-military soils. Since PGRs application did not reduce the stress level, direct application of soil amendments should be considered for stress reduction and improving the biomass quality.
