BLAST searches returned the expected matches or nearest neighbours, and we also did not find any evidence of accidental amplification of microbial contaminants (see [ 28]).
Removing water from contaminated dredged sediments in CDFs is desirable because water removal can reduce the volume occupied by the sediments and can create the aerobic conditions needed for the microbial degradation of many contaminants found in the sediments.
Ms. Mullin described two of the contaminants, found in separate bottles, as ammonia and sodium hydroxide.
-Where is this contaminant found (i.e., is it airborne or waterborne?) -In what environments is this contaminant commonly found (e.g., schools, restaurants, campsites, etc.?) -How is this contaminant spread?
There are, however, genuine dangers associated with another toxic contaminant found in fish: mercury.
Black carbon is a common contaminant, found in emissions from diesel engines and burning farm fields.
Was the same contaminant found in both assemblies?
The study found out that irrespective of the cleaning, the type of container was significant (P < 0.001) in the reduction of microbial contaminants, whereby the aluminium cans had the highest microbial load reduction of 86, 85 and 96 % for TVC, TCC and LAB respectively as compared to 40, 28 and 42 % for TVC, TCC and LAB respectively for plastic jerry cans.
However, we could not find a combination of sodium hypochlorite concentration and duration that did not kill the protonema but did kill the microbial contaminants.
The identity of the microbial contaminants present in no template control (NTC) MDA reactions using 16s rDNA PCR and sequencing were determined and the most abundant taxa are similar to those found in our taxonomic classification of unmapped reads, in particular Burkholdaria and Pseudomonas (Table S7).
