“…Flavobacterium have also been linked to organic enrichment/pollution (Bissett et al. ) and to the breakdown of complex aromatic compounds (Trzesicka‐Mlynarz and Ward ), both of which can be associated with urbanized streams. Therefore, the significantly higher abundance of Flavobacterium in biofilms from these urbanized sites fits the profile of this taxon.…”

“…Within aquatic habitats Flavobacterium are involved in the metabolism of various organic compounds, including carbohydrates and polysaccharides (Bernardet and Bowman 2006), cellulose derivatives (Bernardet and Bowman 2006), and cellulose (Lednicka et al 2000), which could explain their high abundance in the most urban streams and their high abundance on the CES cellulose substrates. Flavobacterium have also been linked to organic enrichment/pollution (Bissett et al 2008) and to the breakdown of complex aromatic compounds (Trzesicka-Mlynarz and Ward 1995), both of which can be associated with urbanized streams. Therefore, the significantly higher abundance of Flavobacterium in biofilms from these urbanized sites fits the profile of this taxon.…”

Urban stream microbial communities show resistance to pharmaceutical exposure

Abstract. Residues of pharmaceuticals are increasingly detected in surface waters throughout the world.In four streams in Baltimore, Maryland, USA, we detected analgesics, stimulants, antihistamines, and antibiotics using passive organic samplers. We exposed biofilm communities in these streams to the common drugs caffeine, cimetidine, ciprofloxacin, and diphenhydramine. Respiration rates in the least urban stream were suppressed when exposed to these drugs, but biofilm functioning in the most urban stream was resistant to drug exposure. Exposure to the antibiotic ciprofloxacin altered bacterial community composition at all sites, with the greatest change occurring in the most urban stream. These results indicated that continuous exposure to drugs in urban streams may select for sub-populations of highly resistant bacteria that maintain community function in response to urban contaminants.

“…As a result, Gammaproteobacteria in sediment samples is more abundant in East Dongting Lake than in the two other lakes. In addition, Flavobacteria played a significant role in biopolymer degradation in sedimentary organic matter (Bauer et al., ; Bissett, Bowman, & Burke, ; Gomez‐Pereira et al., ) and was more highly abundant in East Dongting Lake than in the two other lakes. Deltaproteobacteria and Nitrospira predominated in the sediment samples from Gonghu Bay of Taihu Lake, which is an algae‐dominated and moderately eutrophic area and where massive algal bloom occurs every August.…”

Characterization of sediment bacterial communities in plain lakes with different trophic statuses

Sediment microbial communities play an important role in lake trophic status. This study determined millions of Illumina reads (16S rRNA gene amplicons) to compare the bacterial communities in moderately eutrophic, lightly eutrophic, and moderately trophic regions using a technically consistent approach. The results indicated that the sediments from moderately eutrophic and trophic lake had the higher bacterial diversity than lightly eutrophic lake. Proteobacteria was the most abundant phylum (22.7%–86.2%) across samples from three regions. The sediments from moderately eutrophic region were enriched with Chloroflexi and Nitrospirae. Alphaproteobacteria, Gammaproteobacteria, and Bacteroidetes were enriched in the sediments from lightly eutrophic lake. The sediments from moderately trophic lake contained a high abundance of Acidobacteria and Deltaproteobacteria because of the low pH of the sediments in this lake. In moderately eutrophic region, Nitrospira held an absolute predominance, while Lysobacter and Flavobacterium were the most predominant genera in lightly eutrophic region. Temperature was the main factor influencing the bacterial community in the three lakes. The bacterial communities in the sediment samples obtained from moderately eutrophic lake were associated with nutrient concentration, whereas organic matter and total nitrogen contents mainly influenced the bacterial communities in sediments obtained from lightly eutrophic lake and moderately trophic lake, respectively.

“…These studies have also shown that bacterial community composition changes significantly after cessation of production, such as in periods of fallowing, but the communities do not revert to the composition before the impact, i.e. they are not resilient (Bissett et al, 2006(Bissett et al, , 2007Bissett et al, 2008). A distinctive characteristic composition of bacterial communities in fishfarm sediments cannot be easily drawn due to the high microbial diversity found in marine sediments (Asami et al, 2005;Bissett et al, 2006;Castine et al, 2009;Kawahara et al, 2009).…”

Anthropogenic perturbations in marine microbial communities

Human activities impact marine ecosystems at a global scale and all levels of complexity of life. Despite their importance as key players in ecosystem processes, the stress caused to microorganisms has been greatly neglected. This fact is aggravated by difficulties in the analysis of microbial communities and their high diversity, making the definition of patterns difficult. In this review, we discuss the effects of nutrient increase, pollution by organic chemicals and heavy metals and the introduction of antibiotics and pathogens into the environment. Microbial communities respond positively to nutrients and chemical pollution by increasing cell numbers. There are also significant changes in community composition, increases in diversity and high temporal variability. These changes, which evidence the modification of the environmental conditions due to anthropogenic stress, usually alter community functionality, although this aspect has not been explored in depth. Altered microbial communities in human-impacted marine environments can in turn have detrimental effects on human health (i.e. spread of pathogens and antibiotic resistance). New threats to marine ecosystems, i.e. related to climate change, could also have an impact on microbial communities. Therefore, an effort dedicated to analyse the microbial compartment in detail should be made when studying the impact of anthropogenic activities on marine ecosystems.
