Opis:
Sewage sludge constitutes a source of valuable biogenic raw materials, but it is a carrier of many pathogenic microorganisms and viruses. Subjected to an effective sanitization by means of the process of composting, it is suitable to use in agriculture as fertilizers. The aim of this study was to observe the survival rate of Suid Herpesvirus under the influence of the temperature alone (water bath) as well as in sewage sludge subjected to the process of composting (pile). The samples were taken at different time intervals, and the virus titres were determined. The viruses survived considerably longer under laboratory conditions: at 30°C as long as 21 days, at 40°C - 93 hours, and at 50°C - less than an hour. In the compost pile, in spite of the lack of the thermophylic phase, the total survival time of the viruses ranged from 34 to 44.5 hours, which indicates the vast importance of other physicochemical factors, apart from the temperature, contributing to virus inactivation.

Opis:
The effect of composting and anaerobic fermentations under meso- and thermophylic conditions (37° and 55℃) on the survival of bovine parvovirus (BPV) and Aujeszky’s disease viruse (ADV) in meat wastes has been examined in this study. Viruses were adsorbed on filters and introduced into carriers which were made of meat fragments of different sizes and bones or in the form of suspension they were introduced into the biomass in the course of processes of waste treatment. Carriers were removed at appropriate time intervals and virus titres were determined. The thermoresistant parvovirus survived for the longest time during mesophylic fermentation (almost 70 days), slightly shorter during composting (7-9.5 days depending on the type of carrier) and for the shortest time – at 55℃ (46-76 hours). Its inactivation rate was the fastest in a suspension, slower in meat and bone carriers. ADV inactivation proceeded considerably faster, as compared with BPV. Its active particles were not detected as early as in the 30th minute of thermophylic fermentation, the 6th hour of mesophylic fermentation and at the first sampling time during composting (at the 72nd hour). Total survival time ranged from 50 min to 13 hours. All the tested technologies enabled the effective elimination of ADV and on average twofold decrease in BPV titre. From the study conducted it follows that of both viruses, the BPV should be applied for validation processes of methods used in meat waste processing, particularly if this refers to methods where higher temperature is the factor inactivating pathogens.

Opis:
Survival of bovine enterovirus was studied in animal by-products subjected to sanitization processes. Composting technology and anaerobic digestion under mesophilic (37 °C) and thermophilic (55 °C) conditions were tested in terms of their effectiveness. Viruses were introduced into the biomass in the course of waste treatment processes and virus titres were determined at appropriate time intervals. Technology which allowed the most effective virus elimination, after 2 h, was thermophilic fermentation. During composting, bovine enterovirus survival ranged from 12 to 17 days, whereas the survival time for mesophilic fermentation was 28 days.

Opis:
W pracy zbadano stopień aktywności enzymów pektynolitycznych, celulolitycznych, amylolitycznych i proteolitycznych, a także zdolność do uruchamiania nierozpuszczalnych fosforanów przez fluoryzujące pałeczki z rodzaju Pseudomonas. Bakterie wyizolowano z ryzoplany lnu włóknistego, uprawianego w systemie zmianowania i monokultury. Żaden z izolatów nie wykazywał aktywności enzymatycznej wobec celulozy, natomiast pozostałe wielocukry hydrolizowane były przez wszystkie izolaty. Bakterie były najbardziej aktywne wobec białka. Oceniono również ich właściwości antagonistyczne względem wybranych patogenów grzybowych wyizolowanych z tego samego środowiska. Wszystkie z nich, chociaż w różnym stopniu, hamowały rozwój grzybów.
The degree of pectinolytic, celulolytic, amylolytic and proteolytic enzymes activity as well as the ability to set in motion insoluble phosphates by the fluorescent bacilli of the genus Pseudomonas were evaluated. The bacteria were isolated from the rhizoplane of flax (Linum usitatissimum L.) grown in crop rotation and monoculture. None of the Pseudomonas isolates showed the enzymatic activity towards cellulose, while the other polysaccharides were hydrolyzed by all of them. Bacteria were most active towards protein. Their antagonistic properties towards selected pathogenic fungi isolated from the same environment were also evaluated. Isolates of the genus Pseudomonas were tested towards selected fungal pathogens. All of them inhibited the development of fungi, though to different extent.

Opis:
The agricultural use of sewage sludge is possible on condition of maintaining microbiological and parasitological standards, and one of the most modern methods improving its sanitary state is solar drying. In the presented study, the effect of this process on the elimination of indicator microorganisms (Escherichia coli, Salmonella Senftenberg W775, Enterococcus spp.) and eggs of Ascaris suum introduced into the biomass of sludge was examined. The experiment was carried out in the spring period with a maximal temperature of 18 °C inside the drying plant. Bacteria and parasite eggs were introduced into special carriers (cylinders filled with sewage sludge) and placed at selected points of the drier. The carriers were removed every 7 days and subject to a research procedure in order to estimate the number of bacteria and percentage of live eggs of Ascaris suum. Sanitization of the material was not obtained, since after 28 days of the process the final product contained a large concentration of Enterococcus spp. and S. Senftenberg W775 (105-109 MPNg-1). Only the number of E. coli decreased by 6 log. During the process, the fastest decrease in the number of bacteria was observed in E. coli (ca 0.2 log/day), slower in enterococci (0.02-0.081 log/day), and the slowest in bacilli of the genus Salmonella (0.011-0.061 log/day). Sludge after drying also still contained 57-66% of live eggs of A. suum. The study proved that the solar drying of sludge in the spring period results in a product which poses a hazard for public and animal health and environmental sustainability, and should not be used as a fertilizer.

Opis:
Groch siewny uprawiany w monokulturze cechował wyższy stopień porażenia korzeni w porównaniu ze zmianowaniem, głównie za sprawą grzybów Fusarium oxysporum i F. solani. W okresie kwitnienia porażenie roślin występowało silniej niż w okresie wschodów. Najbardziej wrażliwe na działanie herbicydu Topogard okazały się grzyby: F. oxysporum, Trichoderma viride, Phoma glomerata i Cephalosporium asperum – dawka mniejsza od polowej istotnie hamowała wzrost grzybni. Najmniej wrażliwe na herbicyd były grzyby F. avenaceum, Rhizoctonia solani oraz Zygorhynchus spp.
Pea cultivated in monoculture showed a higher level of root infection, as compared with crop rotation, mainly because of Fusarium oxysporum and F. solani fungi. The plant infection was stronger over flowering than over emergence. The soil fungi F. oxysporum, Trichoderma viride, Phoma ssp. and Cephalosporium asperum proved to be most susceptible to Topogard herbicide. The dose lower than the field one inhibited the mycelium growth significantly. The fungi F. avenaceum, Rhizoctonia solani and Zygorhynchus spp. were least susceptible to the herbicide.
