The origin of pollution may be industrial, radioactive, agricultural, urban mikobiologjike etc.. The study was conducted in the waters of the Adriatic sea ecosystem aims to analyze the microbiological contamination areas. These waters are used for holiday purposes by citizens. The samplings of marine water are taken from the stratum water surface about 10 cm, at a distance 10-20 m by sea coast. These samples are examined in laboratory for determination of two micro organisms, indicators excrements pollution Faecal Coliform （FC） （ISO 9803） and FC, probably Streptococcus Faecal （FS） with Filtrate Membrane Method＇s in specific areas （ISO 7899-2）. In area Velipoja, Albania, the microbiologic elaborated analyses have resulted as follows： For FC and Streptococcus Faecal are given the minimal values FC-50, FS-50 and maximal values FC-90, FS-90 per 100 mL. About the evaluation of reaction （pH） is concluded that in Albania the sea waters coastal zones have a lightly alkaline ambient, where pH value is in the range 7.5-8.3, estimated according to recommended standards 6-9. No cases of red-tide algae development have been observed.展开更多

The comparison of heterotrophs and total coliforms level in sampling are the essence of this research. The object of this study is done in four sampling areas of Durres＇s Harbour basin. In order to compare the level of water microbiologic pollution in four areas of Durres＇s Harbour basin, control area is also studied which is a beach area near the Harbour named Apollonia Beach. The sampling areas were： Ferry Terminal （FT）, Fishery Harbor （FH）, East Zone （EZ）, Fuel Quay （FQ） and Apollonia Beach （AB）, respectively. The period of sample-taking was July-October 2008. The strategy used for this purpose consisted in water insemination with coverage method by means of Petri＇s plates according to respective dilutions in culture media Plate Count Agar （PCA） for heterotrophs and MacConkey for total coliforms. The number of colonies that are formed determines the number of cells at the moment of water insemination, the number of heterotrophs in culture media PCA, respectively. The number of pink and red colonies that were formed determines the number of cells at the moment of water insemination, the number of total coliforms in culture media MacConkey, respectively. The measure ofheterotrophic bacteria and total coliforms used is Colony-Forming Units （CFU）/100 mL seawater. （AB） is within European standards. The richest area with heterotrophs is （FH）, which confirms the fact that it is the most polluted microbiologic area in the Harbour basin of Durres. The richest area with total coliforms is （FT）. The poorest area with heterotrophs and total coliforms is （FQ）.展开更多

Composting is considered as the most promising technique for the valorisation of these products. In this work, the heap composting way is evaluated. Several physicochemical （pH, humidity, salinity, density, organic matter rate, C/N ratio, heavy metals） and some microbiological parameters （total and faecal coliforms, Escherichia coli, streptococci and salmonella） are studied after compost maturation. Main results show that palm compost is characterised by a neutral pH （7.87）, low humidity （40.77%）, high organic matter （50%）, high salinity （2.06 g/L）, acceptable C/N ratio （12.2）, low density （0.43 g/cm3）, high conductivity （3.22 ms/cm）, 109.6 ppm of NH4 and 256.66 ppm of HNO3. Finally, microbiological parameters respect hygiene requirements in comparison with compost quality standards.展开更多
