“…A similar increase in the soil catabolic potential induced by sewage sludge was also reported by Frąc et al (2014), Ros et al (2006a), and Suhadolc et al (2010). Furthermore, the increase in the soil catabolic potential in the sewage sludge-treated objects may have been caused by sedimentary microorganisms (Frąc et al, 2014). The negative effect of sewage sludge, which was increasingly pronounced with time, may have been connected with the depletion of organic matter, which is known to mask the negative effect of xenobiotics on soil microorganisms (Franco-Otero et al, 2012;Moreno et al, 2002).…”

The aim of the study was to evaluate microbial functional diversity based on community level physiological profiling and β-glucosidase activity changes in soil degraded by sulphur mining and subjected to reclamation with various waste. The experiment was set up in the area of the former ‘Jeziórko’ Sulphur Mine (Poland), on a soilless substrate with a particle size distribution of slightly loamy sand. The experimental variants included the application of post-flotation lime, sewage sludge and mineral wool. The analyses of soil samples included the assessment of the following microbiological indices: β-glucosidase activity and functional diversity average well color development and richness). The results indicate that sewage sludge did not exert a significant impact on the functional diversity of microorganisms present in the reclaimed soil. In turn, the application of other types of waste contributed to a significant increase in the parameters of total metabolic activity and functional diversity of the reclaimed soil. However, the temporal analysis of the metabolic profile of soil microorganisms demonstrated that a single application of waste did not yield a durable, stable metabolic profile in the reclaimed soil. Still, there was an increase in β-glucosidase activity, especially in objects treated with sewage sludge.

“…Simultaneously, the brew is a source of energy, in the form of proteins, fats, and residues of starch and cellulose, which is the preferred starting material in terms of suitability for the gasification of the methane fermentation process. Similarly, dairy sewage sludge that is produced as a by-product of the dairy industry is a valuable substrate for methane production because it is rich in fat and protein (Frąc et al 2014).…”

A multi-enzymatic biopreparation of Trichoderma atroviride G79/11 origin was characterized. The fungus showed relatively high cellulase production in a soybean flour-cellulose-lactose medium. Subsequently, based on its post-culture liquid, the biopreparation of the enzyme mixture was developed and characterized. The liquid form of the enzyme mixture reached 22 U cm -3 of cellulolytic activity and its lyophilisate exhibited 1.09 U cm -3 at pH 5.1 and 50 °C. The enzyme mixture was characterized by the following activities: xylanase, β-glucosidase, carboxymethyl cellulase, polygalactouronase, pectinesterase, amylase, lactase, and protease. A method for an efficient conditioning process of organic waste (fruit processing waste, dairy sewage sludge, corn silage, and grain broth) for biogas yield enhancement using the enzyme mixture was proposed. The enzyme mixture increased the efficacy of biogas production by 30% when the lyophilizate (0.5 mg g -1 d.m.) was applied prior to fermentation. A method for conducting the enzymatic conditioning process of organic waste using the enzyme mixture as a pretreatment was proposed. This was part of the optimization of the methane fermentation process to increase the biogas yield. Consequently, after application of the biopreparation, the efficiency of anaerobic digestion of organic waste was improved.

“…The Biolog FF (filamentous fungi) is the rapid spectrophotometric method for metabolic potential assessment of fungi and yeast. Evaluation of sole carbon source utilization patterns based on Biolog FF Plates is widely applied to compare environmental samples as far as profiling of fungal communities catabolic potentials or collating of fungal isolates catabolic activity [14][15][16].…”

The aim of the study was to determine the antioxidant activity, total phenolic content, and total carotenoid content of dried fruit extracts prepared from goji fruits, cranberries, and raisins. Ergosterol content of samples-as a marker of fungal contamination-was measured by LC-MS/MS technique. For the goji fruit samples, fungal community-level physiological profiling and fungal isolate catabolic diversity were tested to evaluate more precisely their fungal contamination. The highest antioxidant activity and total phenolic content were determined for dried goji fruits. Simultaneously, the dried goji fruits were contaminated by ergosterol − 3.8 µg g −1 of dried fruit and the bulk goji fruits were contaminated by heat-resistant fungi. The study of fungal community as a fungal contamination marker of dried goji fruits was performed by a combination of the Biolog FF plates and traditional culture methods which is the first application of this composite analytical approach. Ergosterol content could be an indicator of fungal growth on dried fruits. The Biolog FF microplates can be used as a quick, easy, cheap, and effective method for the detection of heat-resistant fungi in dried fruits.
