It spares no efforts in highlighting the critical nexus between ocean conservation, climate change mitigation and the ecosystem services. The interpretation underscores the threat that unchecked deterioration of marine environment would present for health of the planet and its people. It is evident that the nature-based solutions provide the best options, but the significance of disruptive technologies and innovations cannot be underestimated. However, the decisions pertaining to devising and applying solutions should be informed by scientific reasoning and available evidence. Increasing attention given to blue economy shows the importance of exploring the sustainable solutions by shaping research that helps in identifying the tangible and integrated actions to fast track our progress towards implementing the Sustainable Development Goals.","PeriodicalId":11733,"journal":{"name":"Environmental biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87281425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pharmacological potential of these compounds resides among others in their ability to control the proliferation and growth of cancer cell lines and potent disease-causing microbial agents. Despite recent scientific advances, the way these compounds interact with the body’s molecular structure are still unclear and science still has to discover how the cyanobacterial metabolites interact with cell structures and how cells react to them. In this project, we will study yet unexamined cyanobacterial metabolites, especially the compounds which act as chemical ligands for microRNA (miRNA) -binding sites, making them promising regulators (inhibitors) of gene networks that are involved in various diseases. We will first develop a stable cell line that constitutively expresses a unique miRNA reporter system. Then, we will conduct a screen on chemical compounds discovered in Baltic cyanobacteria to identify small molecules with inhibitory activity and specificity to MIR92b-3p, which has a significant impact on liver cell behavior in humans. We assume that a successful MIR92b-3p inhibitor will bind to the precursors of MIR92b-3p miRNA, disabling the action of either of the two processing enzymes involved in the biogenesis of any miRNA in a cell (Drosha or Dicer), thus affecting the MIR92b function. The discoveries made with these inhibitory chemical molecules could provide insight into the role of the MIR92 pathway in liver diseases and cancer, and possibly, if promising results appear, they may facilitate a strategy for treating some human diseases in the future.","PeriodicalId":11733,"journal":{"name":"Environmental biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73630374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct methods, which included determination of the number of bacterial cells using fluorescence microscopy and Colony Forming Units (CFU) on agar medium, and indirect methods using Alamar Blue (AB) and MTT assays, were evaluated. The chemical compositions of the metal surfaces included: copper, iron, chromium and nickel. Interaction effects of assay and metal compound have been specifically demonstrated in this study. It was found that metal ions reacted with components of the indirect colorimetric tests used in this study (AB and MTT assay). Consequently, those tests gave positive false results. In contrast to the indirect methods, direct counting methods such as microscopy techniques and CFU counting, were successfully applied for evaluation of bacterial adhesion to the metal surfaces. However, considering the limits for the surfaces of the examined samples for microscopy, the determination of the CFU was found to be the best method for testing the adhesion to metal surfaces. The method, combined with the appropriate detachment procedures allowed for a precise determination of the number of bacteria on the entire surface of the evaluated metal samples.","PeriodicalId":11733,"journal":{"name":"Environmental biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87554402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two experimental sequential batch reactors, SBR_A and SBR_B, differed in the time of the reject water inflow (6h40min vs 40min), process temperature (25 vs 29°C), and the © UNIVERSITY OF WARMIA AND MAZURY IN OLSZTYN nitrogen concentrations in raw reject water on the biodiversity of anammox bacteria is not entirely clear. Anammox bacteria need very specific environmental conditions to grow, and their growth is inhibited in nitrogenrich wastewater, which has restricted the application and industrialization of the anammox process (Jin et al. 2012). In general, these bacteria grow very slowly (doubling time at 30-40°C is 10-14 days (Strous et al. 1998; van der Star et al. 2007)), their cell yield is low (Strous et al. 1998, 1999), and they are highly sensitive to changes in environmental conditions, which makes them very difficult to cultivate. Here, we use the completely autotrophic nitrogen removal over nitrite process (CANON) to enable simultaneous partial nitrification and the anammox process in two sequencing batch reactors (SBRs) fed with diluted reject water from anaerobically digested sludge dewatering. We report that the biodiversity of the bacterial community was higher in the SBR with the higher temperature (29°C), shorter time of wastewater inflow (40 min), and six aeration periods per day than in the SBR with the lower temperature (25°C), longer periods of wastewater inflow (6 hours and 40 minutes), and 3 aeration periods per day. IN TRO DUC TION In wastewater treatment, reject water from sludge dewatering has a high ammonium-nitrogen concentration, which if recirculated to the main treatment stream, can cause problems with nitrification and denitrification, and affect the balance of the microbial community. Separate treatment of reject water is a solution to this problem that reduces the nitrogen load of the main stream and improves nitrogen removal (Fux et al. 2002). For treating wastewater with a high concentration of ammonium nitrogen and a low C/N ratio, a combination of partial nitrification with the anammox (anaerobic ammonium oxidation) process is a promising method (Van Loosdrecht and Jetten 1998). In the first stage, about 50% of the influent ammonium can be oxidized to nitrite, reducing the amount of oxygen required by almost a half (Furukawa et al. 2009). This helps to make the combination of processes a cost-effective solution. Many researchers have studied the process from a technological point of view (Fux et al. 2002; Galí et al. 2007; Vega–De Lille et al. 2015; Zhang et al. 2010), but the impact of the high and unstable Karło et al.
