A biotechnological method for metalworking fluids (MWF) wastewater treatment was developed. The research, conducted in a lab-scale bioreactor, proved that the process of eliminating pollutants from MWF wastewater proceeds effectively when the following are applied: multiple reinoculating of biomass by adding active microorganisms into the bioreactor, immobilizing microorganisms on the PVC foam carrier, and carrying out the process in the anoxic/aerobic conditions at phase durations of 0.5 and 5.5 hours, respectively. The above parameters allowed us to obtain the following eliminations: 87% of chemical oxygen demand (COD), 97% of biochemical oxygen demand (BOD5 ), 98% of petroleum ether extractable organic (PEEO) and more than 96% of total content of hydrocarbons determined by infrared (IR) spectrophotometry. The chromatographic analyses showed almost complete reduction of oily hydrocarbons contained in the used MWF.

Escherichia coli suspension was introduced into meat and bone carriers of different sizes and a number of the bacteria was analysed at suitable time intervals. The cycles analysed were characterised by a slightly different distribution of temperature, but it was sufficient to inactivate the rods in all types of the carriers. The quickest elimination rate of E. coli (0.1-0.14 log/h) was noted in the cycle in which the temperature ranged from 50 to 60°C. In the other cycles, with lower temperatures generated, the decrease in the bacteria's numbers was 0.03-0.04 log/h. However, the inactivation of the introduced pathogens occurred in both cycles. When properly conducted, a process of composting wastes guarantees retaining environmental safety.

nr 1

W pracy przedstawiono przegląd literatury dotyczącej badań genetycznych ważnej uprawnej rośliny oleistej strefy klimatu umiarkowanego, jaką jest rzepak ozimy. Zaprezentowano metody biotechnologiczne, takie jak transformacje genetyczne z użyciem wektorów bakteryjnych oraz metodą wyciszania genów, ukierunkowana mutageneza, a także selekcja z użyciem markerów genetycznych, w odniesieniu do prowadzonych doświadczeń hodowlanych. Metody te stosowane są w celu modyfikacji i polepszenia ważnych gospodarczo cech, takich jak odporność na choroby i szkodniki, plon nasion, plon oleju, skład kwasów tłuszczowych w oleju nasion, występowanie związków aktywnych biologicznie w oleju i wytłoku oraz zawartość włókna w okrywie nasiennej. Podkreślono znaczenie identyfikacji specyficznych markerów genetycznych i ich zastosowania do selekcji w programach hodowli. Wskazano na rozwój nowej, interdyscyplinarnej dziedziny, określonej jako hodowla molekularna. Przedstawiono również praktyczne zastosowanie różnego rodzaju markerów genetycznych, identyfikujących geny i rejony genomu sprzężone z określonymi cechami, z włączeniem markerów opracowanych w IHAR – PIB, Oddział w Poznaniu.

Plant is one of the major forms of life on earth. It can produce its own food but cannot move about. Plants have well organized structures. They are beautiful and they determine local climates and are used as live fences. They phytoremediate and cool our environment. They provide us with oxygen, medicines, fuel, timber, recreation, industrial products; preservatives, pesticides in addition to all the three necessities of life: food, clothing and shelter. They purify the air and water bodies. It is therefore impossible to talk about life without plants because of their importance to the balance of nature. However, people have altered and often degraded their environment, though it has been taking place so gradually that its effects have not been drastically felt. Despite the enormous benefits of plants to humanity, they are disappearing at alarming rates. The reasons for this loss are many and include many anthropogenic activities. It is therefore quite imperative to ensure their effective conservation. This paper summarizes available information about the direct and the indirect benefits of plants and suggests some important measures to ensure their posterity. I hope, by bringing this information together, people will appreciate our plants and be frugal in using them.

Plant parasitic nematodes feed and develop on many economically important crop species causing high losses amounting to many billions dollars every year throughout the world. This negative balance make them the second most damaging group of pathogen/pests after fungi. Additionally, some of them are viral vectors that is contributing to their higher extent of harm caused. Nevertheless, plant nematology is underrepresented in terms of staff in comparison to other fields focusing on plant pests and pathogens. Development in biotechnology however, caused also the development in plant nematology providing tools for characterization or identification of nematode species. New modern diagnostics approaches are continuously described on the basis of genome analysis. Also in Plant Protection Institute – National Research Institute several studies are conducted that concentrate on populations variability of economically important nematode species, diagnostics, and plant-nematode interactions. Another aspect of interest involving biotechnologists is characterization of host reaction to plant-parasitic nematode infection and description of genes participating in production of resistance against those pests. The use and generation of resistant cultivars is a powerful tool in reducing the spread of some quarantine nematodes. Since nematodes are very difficult to destroy, their reduction is a major challenge for plant protection. The use of biotechnology along with other alternative approaches may help to achieve this goal.
