“…This study was prompted to obtain a new BS obtained from slaughterhouse sludge to bioremediate a soil contaminated with the oxyfluorfen herbicide, which exerts a persistent toxic effect on soil biological properties (Gómez et al 2014;Rodríguez-Morgado et al 2014;Franco-Andreu et al 2016;Campos et al 2019). Our hypothesis is supported by the existence of other BS obtained by enzymatic hydrolysis process from different organic wastes such as sewage sludge, chicken feathers, okara, rice bran, etc.…”

“…There is an abundant bibliography that suggests understanding the behaviour of any xenobiotic in soil requires the study of biological parameters (Campos et al 2019;Wołejko et al 2020). This is because these biological parameters react much faster than physical and chemical ones (Kadian et al 2012;Franco-Andreu et al 2016;Orts et al 2017).…”

The use of organic matter is a highly accepted environmental practice among scientists for the bioremediation of polluted soils. In this manuscript we study under laboratory conditions the bioremediation capacity of a new biostimulant obtained from slaughterhouse sludge in a soil polluted by the oxyfluorfen at a rate of 4 l ha−1 (manufacturer’s rate recommended) over a 90-day period. We determined its effects on dehydrogenase, urease, β-glucosidase and phosphatase activities, the soil microbial community structure and the evolution of the herbicide in soil. Possibly due to the high content of low molecular weight proteins in the biostimulant, the enzymatic activities were stimulated mainly at the beginning of the experiment. Soil biological parameters were inhibited in oxyfluorfen-polluted soil. At the end of the experiment and compared with the control soil, dehydrogenase, urease, β-glucosidase, and phosphatase activities significantly decreased by 47.8%, 50.5%, 36.4%, and 45.5% in the oxyfluorfen-polluted soil. At 5 days into the experiment, the use of the biostimulant in oxyfluorfen-polluted soils decreased soil enzymatic activities and microbial community inhibition. At the end of the incubation period the oxyfluorfen concentration had decreased by 60% in the polluted soil and amended with biostimulants. These results suggested that the use of this biostimulant with higher amounts of low molecular weight proteins and peptides had a positive effect on the remediating oxyfluorfen-polluted soils. Therefore, this study provides the use of a new biostimulant obtained from slaughterhouse sludge by enzymatic hydrolysis processes used in the bioremediation of a soil polluted by the oxyfluorfen herbicide.

Role of Chlorella sp. and rhamnolipid 90 in maintaining homeostasis in soil contaminated with bisphenol A

Purpose The knowledge about the impact of BPA on soil health does not correspond to the great interest in its analogues. Therefore, a study was conducted to determine the potentially negative impact of BPA on the biochemical properties of soil. The study also evaluated the effectiveness of two biostimulants in eliminating potential homeostasis disorders caused by BPA. Materials and methods A pot experiment was conducted under supervised conditions. BPA at five contamination levels was added to the soil of the granulometric composition of sandy loam at 0, 0.1, 2, 40 and 800 mg BPA kg −1 of a dry matter (DM) of soil. The biochemical activity of the soil was interpreted through the activity of dehydrogenases (Deh), urease (Ure), catalase (Cat), acid phosphatase (Pac), alkaline phosphatase (Pal), arylsulphatase (Aryl) and β-glucosidase (Glu) whose activity was determined on days 5, 15 and 45 of the study. The biostimulative potential of Chlorella sp. and rhamnolipid 90 (which eliminates the undesirable effects of BPA on the parameters) was expressed with IF B-the factor of the impact of increasing of bisphenol (BP) soil contamination levels. The response of spring barley to increasing BPA pressure was analysed with the plant resistance index (RS). The study was made more comprehensive by determination of the macronutrient content in the plants. Results and discussion The sensitivity of individual enzymes to increasing bisphenol pressure on the 45th day of the experiment can be arranged in the following sequence: Deh > Ure > Glu > Pac > Cat > Aryl > Pal. Biostimulation of soil with Chlorella sp. gave better results than with rhamnolipid 90. A compilation of BPA 800 mg BPA kg −1 DM of soil and Chlorella sp. brought about an increase in the activity of Glu on the 45th day of the experiment and Pac, Pal and Aryl on the 5th day. Only at this contamination level did BPA stimulate the crop growth in all the parallel plots except in those biostimulated by Chlorella sp. Only algae significantly reduced the negative BPA impact on the N, Ca and K content in spring barley. Conclusions The experiment emphasised the significant inhibitory impact of BPA on the biochemical activity of soil which, in consequence, upset the microbial balance of soil processes. Chlorella sp. played a more important role in maintaining the soil homeostasis than rhamnolipid 90, which did not correspond to its negative impact on the yield of spring barley.

Herbicides help increase agricultural yields significantly, but they may negatively impact the life of non-target organisms. Modifying the life cycle of primary producers can affect other organisms in the food chain, and consequently in the whole ecosystem. We investigated the effect of common herbicides Roundup® Classic Pro (active substance glyphosate) and Garlon New (triclopyr and fluroxypyr) on aquatic organisms duckweed Lemna minor and green algae Desmodesmus subspicatus, and on the enzymatic activity of soil. We also compared the effects of Roundup® Classic Pro to that of a metabolite of its active substance, aminomethylphosphonic acid (AMPA). The results of an algal growth test showed that AMPA has a 1.5× weaker inhibitory effect on the growth of D. subspicatus than the Roundup formula, and the strongest growth inhibition was caused by Garlon New (IC50Roundup = 267.3 µg/L, IC50Garlon = 21.0 µg/L, IC50AMPA = 117.8 mg/L). The results of the duckweed growth inhibition test revealed that Roundup and Garlon New caused 100% growth inhibition of L. minor even at significantly lower concentrations than the ready-to-use concentration. The total chlorophyll content in the fronds was lowest when Garlon New was used. The highest dehydrogenase activity was observed in soil treated with Garlon New, and the lowest in soil treated with Roundup® Classic Pro. The results of this study showed that all three tested substances were ecotoxic to the tested organisms.
