Dear all,
Can someone please help me finding the reason why I have about 20% of total bacterial population (studied via 16S) as cyanobacteria in the biofilters which is used for the treatment of oil sand process wastewater. Their percentage 0.23% in the beginning but then increased to more than 20% after treatment of 8 hours in all the samples. Is it that algal biofilms are being formed and the match is due to plastids (e.g. endosymbiont theory)? Or do cyanos really play some role in degradation?
Thank you
PS: the biofilter is just sand column
