Abundance and biomass of bacteria in two Arctic glacial fjords
PublicationTotal numbers and biomass of bacterioplankton in water in two glacial fjords off west Spitsbergen have been studied. Samples were collected from different water depth layers - from the surface to 80-90 m. Total bacterial number (TBN), biomass and morphological structure were determined by the acridine orange direct count method. The highest values of TBN and biomass in the water column were found on stations situated adjacent...

Effect of high pressure of selected bacteria at subzero temperature
PublicationCelem pracy było określenie przeżywalności wybranych bakterii gramdodatnich i gramujemnych poddanych działaniu podwyższonego ciśnienia w zakresie od 60 do 193 MPa w ujemnej temperaturze. Wrażliwość bakterii na zwiększone ciśnienie zależy od fazy wzrostu w jakiej się one znajdują. Z reguły bakterie gramdodatnie są bardziej odporne na ciśnienie niż bakterie gramujemne. Wykazano, że różnice w odporności pojawiają się nie tylko pomiędzy...

Sulphate reducing bacteria in groundwater intakes in Gdańsk Region.
PublicationPraca przedstawia wyniki badań określające występowanie bakterii redukujących siarczany w wodach podziemnych ujmowanych z utworów kredowych oraz z utworów czwartorzędowych w regionie gdańskim. Bakterie te okresowo znajdują odpowiednie warunki do wzrostu w środowisku wód podziemnych i w wyniku procesów metabolizmu produkują siarkowodór pogarszający cechy organoleptyczne wody. W celu ograniczenia niekorzystnych zmian jakości wody...

Bee Pollen and Bee Bread as a Source of Bacteria Producing Antimicrobials
PublicationThe principal objective of the study was the isolation and identification of bacteria that are present in mature bee bread (BB) and dried (ready for selling and consumption) bee pollen (BP). Obtained isolates were screened for their potential to inhibit select human pathogenic bacteria and their ability to produce enzymes of particular industrial importance. Four and five samples of BP and BB, respectively, were used for the study....

Characteristic and specificity of protease activity of thermophilic bacteria Meiothermus ruber
PublicationThe primary purpose of research was to establish the possibility of using thermophilic bacteria Meiothermus ruber as a source of proteolytic enzymes. The main reason of searching new proteases is their commercial value especially in production of detergents, food, pharmaceuticals, leather, diagnostics or waste management. The development of this type processes will be possible by utilization of enzymes which have unique characteristics...

total number and biomass of bacteria in drinking water distribution systems.
PublicationIn the vast water supply network using traditional methods of treatment it is often impossible to maintain a constant and acceptable microbiological quality of water. In Poland the main reason of bacterial re-growth is presence of organic matter and nutrients in the circulating water and prolonged water retention in the network systems due to the decrease of water consumption, which has been observed for the last 20 years. In the...

Occurrence of antimicrobial resistant bacteria in environment and the statistical analysis of this phenomenon
PublicationIntroduction: In this study the occurrence of antimicrobial resistance patterns among fecal indicators (Escherichia coli and Enterococcus spp.) was analyzed in water and wastewater samples. The trends in antimicrobial resistance were analyzed using basic statistical methods. Methods: Samples were obtained from two local watercourses (Oliwski Stream and Reda River) as well as from the wastewater treatment plant (WWTP) Gdansk - Wschod....

Sulphate-reducing bacteria, their properties and methods of elimination from groundwater
PublicationRutynowa kontrola jakości bakteriologicznej wód podziemnych przeznaczonych do spożycia nie obejmuje badania pod względem obecności bakterii charakterystycznych dla tego środowiska tj. bakterii redukujących siarczany (BRS), które mogą mieć negatywny wpływ na jakość wody. Stwierdzono obecność tych bakterii w wodach podziemnych rejonu Gdańska. Wyizolowano konsorcja BRS, które wykazywały preferencję do wykorzystywania mleczanu sodu...
