The microbic recolonisation of the Lake of Orta ecosystem after liming (carbonation)
The purpose of this study was to assess whether the work aimed at restoring the health of the Lake of Orta is having the desired effects. Both the sediment and the water in contact with it were examined, assessing the presence of both aerobic and anaerobic bacteria, yeasts and mycetes, as well as studying the most significant physical and chemical parameters. A slight increase in mycetic species was noted as well as a clear increase in bacterial species. After liming, nitrification by microorganisms, which had previously been blocked, recommenced. Denitrification also started again, and over the next few years it should lead to a reduction in nitrate concentration.
