“…The addition of biodiesel ultimately resulted in a variety of additional simple carbon sources (free fatty acids, fatty acid methyl esters, glycerol, methanol, and others) as well as phosphorus and nitrogen sources accessible to all microbial species, such that sequencing of the complete water phases from the storage cultures (1:5) for the addition of biodiesel documented an immediate expansion of microbial diversity to include the yeasts and molds (Figure 5 right). This has immediate implications for the complexity and robustness of biofilms formed, as well as the metabolic repertoire of the contaminant running off in terms of degradation capacity and microbially assisted corrosion [123–126].…”

Since 2008, legislative initiatives for climate protection and reduced dependency on fossil resource imports led to the introduction of biofuels as CO2-reduced alternatives in the heating oil sector. In the case of biodiesel, the oil industry or its customers were confronted with accelerated and escalating microbial contaminations during heating oil storage. Since then, other fuel alternatives, like hydrogenated vegetable oils, gas-to-liquid products (GtL), or Oxymethylenether (OME) have been or will be developed and potentially introduced to the market. In this study, we use online monitoring of microbial CO2 production and the simulation of onset of microbial contamination to investigate the contamination potential of fuel alternatives during storage. As reference and blends, fossil heating oils of various refineries, in the course of this from various crude oils, and refinery processes reveal considerable variation in potential microbial activity. Oxymethylene ethers have an antimicrobial effect, while various forms of biodiesel confirm the promotion of microbial activity and diversity. The paraffinic Fischer-Tropsch products and biogenic hydrogenation products demonstrate high resistance to microbial contamination despite allowing microbial diversity. Through an array of analytics, including advanced chromatography coupled mass spectrometry, elemental analysis, and microbial sequencing, we can discuss critical fuel properties that promote or inhibit microbial contaminations. In summary, novel, non-fossil heating oils show different strengths and weaknesses for long-term storage. Designing blends for microbial activity reduced long-term storage might be an option. While being niche products, these fuels will contribute to the rapid reduction of fossil resource use.

“…The polymeric nanoparticles of organic origin when used in drilling fluids would have biological significance in prevention and treatment of this form of microbial corrosion by preventing formation of biofilm on the metal surface [31]. Also, polylactic acid (PLA) has potential application for this purpose.…”

New technologies are often sought to mitigate the problems associated with traditional drilling fluid formulations. Nanotechnology provides an alternative. A particle size of matter in the range of 1–100 nm in diameter (d.nm) is referred to as nanoparticle. Nanoparticles are broadly divided into various categories depending on their morphology, size and chemical properties. This size range lends their application in science and engineering. In rotary drilling operations where drilling fluid is at the center, performance and optimization issues have been observed. Use of polymer nanoparticles in mud formulations have been considered due to desirable properties such as wide specific surface area, high temperature stability and pollution resistance. Areas of application and advantages include improvement in mud rheology, fluid loss properties, improved lubricity, filter against hazard materials and cost effectiveness. Biodegradable polymeric nanoparticles possess the outlined properties and would continue to offer wider applications in drilling fluid technology now and in the nearest future due to their stable, film forming and gelatinization characteristics. To reliably estimate the quantity of polymeric nanoparticles to use, size and shape should be considered before concentration to apply to make prediction easier. Dispersion of different shapes, sizes and structures of polymeric nanoparticles might be a consideration to enhance polymer influence on fluid formulations.

“…It shows a low porosity structure and the same compressive strength as the untreated sample concrete immersed in water and cement-based biocides coatings, whose copper phthalocyanine, cuprous oxide, and potassium nitrate were functional components. Many other biocide agents suitable for concrete were described in the literature, such as quaternary ammonium compounds, halogenated complex, metal oxide, silver, and tungsten powder [ 31 , 32 , 33 ].…”

Bacterial colonization of surfaces is the leading cause of deterioration and contaminations. Fouling and bacterial settlement led to damaged coatings, allowing microorganisms to fracture and reach the inner section. Therefore, effective treatment of surface damaged material is helpful to detach bio-settlement from the surface and prevent deterioration. Moreover, surface coatings can withdraw biofouling and bacterial colonization due to inherent biomaterial characteristics, such as superhydrophobicity, avoiding bacterial resistance. Fouling was a past problem, yet its untargeted toxicity led to critical environmental concerns, and its use became forbidden. As a response, research shifted focus approaching a biocompatible alternative such as exciting developments in antifouling and antibacterial solutions and assessing their antifouling and antibacterial performance and practical feasibility. This review introduces state-of-the-art antifouling and antibacterial materials and solutions for several applications. In particular, this paper focuses on antibacterial and antifouling agents for concrete and cultural heritage conservation, antifouling sol–gel-based coatings for filtration membrane technology, and marine protection and textile materials for biomedicine. In addition, this review discusses the innovative synthesis technologies of antibacterial and antifouling solutions and the consequent socio-economic implications. The synthesis and the related physico-chemical characteristics of each solution are discussed. In addition, several characterization techniques and different parameters that influence the surface finishing coatings deposition were also described.
