CULTIVAREA ALGELOR CHLORELLA VULGARIS BEIJER, SYNECHOCYSTIS SALINA WISL., PHORMIDIUM FOVEOLARUM (MONT.) GOM. ŞI TRIBONEMA VIRIDE PASCH. PE MEDII CU ADAOS DE APE REZIDUALE ORĂŞENEŞTI

Abstract

Pentru cultivarea speciilor de alge (Chlorella vulgaris, Synechocystis salina, Phormidium foveolarum şi Tribonema viride) au fost utilizate mediile cu adaos de ape reziduale de la Staţia de Epurare Biologică, în concentraţii de la 1 la 50%. Pentru fiecare specie au fost stabilite concentraţiile optimale ale mediilor de cultivare. Cea mai înaltă cantitate de biomasă a fost obţinută după 10-15 zile de cultivare. Pentru specia Chlorella vulgaris cel mai favorabil s-a dovedit a fi mediul cu adaos de 5% (17,55 g/l), pentru Synechocystis salina mediul cu adaos de 20% (16,56 g/l), pentru Phormidium foveolarum – mediul cu adaos de 10% (3,36 g/l), iar pentru Tribonema viride – mediul cu adaos de 30% (2,10g/l)For the cultivation of algae species (Chlorella vulgaris, Synechocysti s salina, Phormidium foveolarum and Tribonema viride ) were used media with added of wastewater from Biological Wastewater Treatment Plant in the range of 1 to 50%. For each species were set to its optimum cultivation media. The best results were obtained after 10-15 days of cultivation. The highest amount of biomass of the species Chlorella vulgaris was at the 5% medium (17.545 g/l), for the species Synechocystis salina peak was on average with 20% (16.556 g/l), Phormidium foveolarum–medium with added 10%(3.36 g/l), and for the species Tribonema viride–the 30% medium (2.1 g/l). Common to all species was the medium with added to 10% of the waste water, but the obtained results vary from case to case.
