“…Hydrogen sulfide, which is produced by sulfate-reducing bacteria (SRB) under anaerobic conditions in sediments or biofilms at the bottom of sewerage pipeline, diffuse into a thin liquid films at the crowns of the pipelines in sewerage systems. Hydrogen sulfide and other sulfur compounds, such as S 2 O 3 - and S 0 , are then oxidized biotically or abiotically, such that sulfate-producing bacteria accumulate on the pipeline surface ( Okabe et al, 2007 ; Satoh et al, 2009 ; Soleimani et al, 2013 ; Ling et al, 2014 ). Calcium, silicon, and aluminum oxides, and carbonates in cured cement react with biogenic sulfuric acid, causing the corrosion of gypsum into ettringite, and resulting in a continuous decline in pH value on the surface ( Vincke et al, 2001 ).…”

“…Thiothrix sp., Thiobacillus plumbophilus, Thiomonas intermedia, Halothiobacillus neapolitanus, Acidiphilium acidophilum and Acidithiobacillus , and A. thiooxidans accounted for approximately 70% of EUB338-mixed probe-hybridized cells and was the most dominant SOB in the heavily corroded concrete sample ( Okabe et al, 2007 ). ASOB, such as Thiobacillus thiooxidans and Thiobacillus intermedius , are primarily responsible for concrete structural failure of concrete structures in sewerage systems because they can survive in low pH conditions and have the ability to generate a highly acidic environment ( Mori et al, 1992 ; Soleimani et al, 2013 ). In addition, Mycobacterium spp.…”

The undesired sulfur cycle derived by microbial population can ultimately causes the serious problems of sewerage systems. However, the microbial community characters under dynamic environment factors in actual sewerage system is still not enough. This current study aimed to character the distributions and compositions of microbial communities that participate in the sulfur cycle under the dynamic environmental conditions in a local sewerage system. To accomplish this, microbial community compositions were assessed using 454 high-throughput sequencing (16S rDNA) combined with dsrB gene-based denaturing gradient gel electrophoresis. The results indicated that a higher diversity of microbial species was present at locations in sewers with high concentrations of H2S. Actinobacteria and Proteobacteria were dominant in the sewerage system, while Actinobacteria alone were dominant in regions with high concentrations of H2S. Specifically, the unique operational taxonomic units could aid to characterize the distinct microbial communities within a sewerage manhole. The proportion of sulfate-reducing bacteria, each sulfur-oxidizing bacteria (SOB) were strongly correlated with the liquid parameters (DO, ORP, COD, Sulfide, NH3-N), while the Mycobacterium and Acidophilic SOB (M&A) was strongly correlated with gaseous factors within the sewer, such as H2S, CH4, and CO. Identifying the distributions and proportions of critical microbial communities within sewerage systems could provide insights into how the microbial sulfur cycle is affected by the dynamic environmental conditions that exist in sewers and might be useful for explaining the potential sewerage problems.

“…In other cases, the formation of microbial biofilm on the surface of cement-based materials can provide a protective layer against biological deterioration, e.g. either by the excretion of protective organic polymers (EPS = ExoPolymeric Substances), where beneficial precipitation of calcium carbonate can occur for example [69], or by the proliferation of non-aggressive microbes capable of competing with undesirable microorganisms [70,71]. Also, the metabolites produced by some fungi or lichens, such as oxalic acid, can protect Ca-bearing materials by the precipitation of calcium oxalate at their surface [72,73].…”

Building materials can be exposed to microorganisms (mainly bacteria, fungi and algae) in almost every aqueous medium or damp environment, water being the indispensable condition for life development. The activity of microorganisms can be responsible for mineralogical, chemical and microstructural damage to the material (biodeterioration). Deleterious effects can also concern the aesthetics of a building (proliferation of colored biological stains on façades and roofs) or the quality of indoor air (presence of microorganisms in damp buildings). However, microorganisms can also have positive effects (healing of materials) and their action is explored through the development of bio-based protective systems intended for building materials. In all cases, understanding interactions between building materials and microorganisms is an indispensable step toward the development of more sustainable, better quality, safer structures in many environments. This paper presents two examples where the action of microorganisms has-or is likely to have-strong impact on the durability and safety of concrete structures. The first example concerns the biodeterioration of concrete in agricultural and agro-food environments. The second example is that of the abiotic and biotic reactivity of nitrates in repository of intermediate-level long-lived nuclear wastes. The paper presents the approaches used to explore and understand the phenomenology of biogeo-chemical interactions in these complex environments. These studies notably comprise the development of test methods and experimental pilots to enable these explorations to be carried out. Current shortcomings in the scientific literature and in the standardization environment are also highlighted.

“…Apart from remediating heavy metals (usually accompanied by formation of NPs), biofilms can be applied on concrete surfaces. While biofilms have been more widely applied to protect the metal surfaces from corrosion (Zuo, 2007), several applications to concrete have been reported (Soleimani et al, 2013a;Soleimani et al, 2013b;Soleimani et al, 2013c). An E. coli DH5α biofilm can successfully cover mortar samples, continue to grow (almost doubling the thickness) despite application of sulfuric acid down to pH of 3, and reduce leaching of Ca 2+ by 23-47% compared to samples without the biofilms (Soleimani et al, 2013a).…”

Climate change, infrastructure resilience, and resource recovery from waste have emerged as grand challenges for civil engineers in the 21st century. Wicked problems associated with these global grand challenges are necessitating innovative, multidisciplinary thinking and multiscale, integrated solutions that are spurring the development of a new field-construction biotechnology. While the field of construction biotechnology spans multiple scales, this review highlights the promise and potential of nanoscale (<100 nm) biotechnological applications to civil engineering. While the field of nanotechnology has revolutionized other industries, applications of nanotechnology in civil engineering have remained limited due to techno-economic and environmental barriers. Biological production of functional nanoparticles (NPs), however, offers new economical routes to develop resilient, high-performance cementitious materials while simultaneously addressing critical needs related to wastewater treatment and resource recovery. Recent research has elucidated that biological production of NPs exhibit preferred-and genetically controllable-morphological characteristics that could tailor the structure-property relationships of civil engineering materials. The natural ability of microorganisms to immobilize heavy metals (eg, Hg, Cr, Zn, Cd, Cu, Ag)-and the programmability of microorganisms to do so via synthetic biology-as well as their ability to sequester greenhouse gases and neutralize volatile organic compounds affords civil engineers a grand opportunity to treat wastewater, recover rare earth elements, and minimize air pollution. In addition to featuring state-of-the-art research in the field, this review summarizes the opportunities and challenges of nanoscale biotechnology and proposes a roadmap of research for civil engineers of the 21st century.
