Review ArticleOpen accessEvery word in the titleAbout the Cyanobacteria and StromatolitesFlorian Ion Tiberiu Petrescu, Liviu Marian UngureanuStromatolites are layered biochemical accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), especially cyanobacteria. Stromatolites occur widely in the fossil record of the Precambrian but are rare today. Life on Earth was born at least 3.7 billion years ago, but since then the number of living things has … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 17 Feb 2022 · 8,230 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHYPOLITHIC CYANOBACTERIA COLONIZATION OF QUARTZ AT SOUTH DESERTRoda F. Al-ThaniHypolithic microbial communities (found underneath rocks) were encountered in the southern desert of Qatar where quartz rocks are ubiquitous and are a substrate for hypoliths. These hypoliths thrive where extreme temperature, moisture stress and high light intensity limit the occurrence of higher plants and animal life. A small-scale ecological survey indicated that 80% of the quartz rocks in the area … …OnLine Journal of Biological Sciences, Vol. 14, Issue 1 · 11 Feb 2014 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExperimental Evidence for the Role of Natural Radioactivity in Influencing Viability of Commensal MicroorganismsMarco RuggieroTo investigate the feasibility of culturing edible microbes, classified as probiotics for human consumption, in commercially available, naturally radioactive, mineral water; to compare their viability with that of the same microbes cultured in deuterium-depleted water. A diversified array of probiotics was cultured in two different naturally radioactive mineral waters, or in deuterium-depleted water in order to assess the effects of … …American Journal of Immunology, Vol. 17, Issue 1 · 26 May 2021 · 8,741 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Diurnal Variation of Dissolved Oxygen in a Eutrophic Polymictic ReservoirAnusha BalangodaTo evaluate the diurnal and seasonal Dissolved Oxygen (DO) variations and their effects on water quality, a comprehensive study was conducted in a eutrophic polymictic reservoir under artificially aerated and non-aerated conditions. The effect of aeration among sampling locations and along the water column of DO and DO saturation and diurnal variation of DO, water temperature, pH and conductivity was … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 24 Jan 2017 · 8,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,669 accessesView PDFCite

Research ArticleOpen accessIn the abstractStructure Prediction and Binding Site Analysis of Hepatotoxic Microcystin-LR Degrading MlrC-Like Protein from Burkholderia sp. using Computational ApproachesDhananjaya P. Singh, Ratna Prabha, Vivek Keshri, P.C. AbhilashMicrocystin-LR (MCYST-LR) is a well characterized hepatotoxic heptapeptide produced by various species of cyanobacteria including Microcystis aeruginosa. Burkholderia is a genus of bacteria with cyanobacterial toxins degrading property. This study predicts the structure of microcystin degrading MlrC-like protein from Burkholderia sp. strain CCGE1002 that has microcystin degradation capability. Binding interaction of MlrC-like protein with MCYST-LR was studied. Three-dimensional model of … …Current Research in Bioinformatics, Vol. 5, Issue 1 · 10 Jun 2016 · 8,069 accessesView PDFCite
Review ArticleOpen accessIn the abstractEffects of Intermittent Artificial Circulation in Summer Months on Chlorophyll a Concentration in a Small Eutrophic ImpoundmentAnusha Balangoda, Shafiqur Rahman, G. PadmanabhanImpact of artificial circulation on total algal biomass (as chlorophyll a integrated over depth) in a small eutrophic impoundment in the Northern Great Plains, was monitored over three consecutive summers. Chlorophyll a concentration and nutrient concentrations were measured at depths along water columns under aerated and non-aerated conditions at four sampling locations. Aeration destratified the water column, which resulted in … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 14 Nov 2015 · 7,303 accessesView PDFCite

Research ArticleOpen accessIn the abstractBacteria on Human SkinRichard W. Hyman, Farbod Babrzadeh, Curtis Palm et al.Problem statement: Human skin is a large (~ 1.75 m2) organ containing a large number of ecologically distinct sites. These sites harbor a variety of distinct microbiomes. One challenge is to define the microbiome at every site. We chose two interesting sites: the base of the Front of the neck and the base of the Back of the neck (the … …Current Research in Microbiology, Vol. 2, Issue 2 · 23 Feb 2012 · 8,204 accessesView PDFCite
