Natural-abundance (13)C-nuclear magnetic resonance was used to probe the intracellular organic solute content of the moderately halophilic bacterium Tetragenococcus halophila. When grown in complex growth media supplemented or not with NaCl, T. halophila accumulates glycine betaine and carnitine. Unlike other moderate halophiles, T. halophila was not able to produce potent osmoprotectants (such...
Effects of ultraviolet-B radiation on the photosynthesis of seagrasses (Halophila engelmanni Aschers, Halodule wrightii Aschers, and Syringodium filiforme Kütz) were examined. The intrinsic tolerance of each seagrass to ultraviolet-B, the presence and effectiveness of photorepair mechanisms to ultraviolet-B-induced photosynthetic inhibition, and the role of epiphytic growth as a shield from ult...
(Current Biology 16, R395–R400; June 6, 2006) In our recent primer, "The Co-Evolution of Life and Earth," when discussing the evolution of hydrogenosomes ("Example 2"), we accidently wrote "Recently, genetic material was extracted from the hydrogenosome of Trichomonas ovalis .." There is no organism called ‘‘Trichomonas ovalis.’’ Rather, we meant to write ‘‘Nyctotherus ovalis.’’ For more detail...
This research was conducted from January to March 2021 in the seagrass ecosystem of Amahai village, Maluku Tengah Regency. study aims analyze structure communities, identify utilization forms ecosystem, and formulate management directives waters. Environmental parameter measurements included temperature, salinity, pH, current speed, substrate conditions. Data collected use were carried out obse...
Seagrass condition, resilience and ecosystem services are affected by the below-ground tissues (BGr) but these rarely monitored. In this study we compiled historical data across northern Australia to investigate biomass allocation strategies in 13 tropical seagrass species. There was sufficient undertake statistical analysis for five species: Cymodocea serrulata, Halophila ovalis, Halodule unin...
Halorhodospira halophila is among the most halophilic organisms known. It is an obligately photosynthetic and anaerobic purple sulfur bacterium that exhibits autotrophic growth up to saturated NaCl concentrations. The type strain H. halophila SL1 was isolated from a hypersaline lake in Oregon. Here we report the determination of its entire genome in a single contig. This is the first genome of ...
BACKGROUND The application of radiofrequency electrocautery to a standard, open-ended transseptal needle has been used to facilitate transseptal puncture (TSP). The purpose of this study was to determine the incidence of cardiac tissue coring when this technique is used. METHODS AND RESULTS A model using excised swine hearts submerged in a saline-filled basin was developed to simulate TSP wit...
The potential difference across the protoplasm of impaled cells of two American species of Halicystis is compared. The mean value for H. Osterhoutii is 68.4 mv.; that for H. ovalis is 79.7 mv., the sea water being positive to the sap in both. The higher potential of H. ovalis is apparently due to the higher concentration of KCl (0.3 M) in its vacuolar sap. When the KCl content of H. Osterhoutii...
Oxygen transfer has been studied in the Pseudomonas ovalis fermentation that quantitatively converts glucose into gluconic acid. The rate of oxygen uptake by this system was correlated with aeration rates and agitator speeds over wide ranges of these variables, by the introduction of a liquid expansion term. The technique described provides a biological method for studying oxygen transfer in th...
INTRODUCTION Congenital cholesteatoma of the middle ear is un uncommon and yet not well-defined disease. Only few cases of cholesteatoma in thefossa ovalis with unusual clinical presentation have been reported in medical literature. CASE REPORT We reported a 16-year-old girl with congenital cholesteatoma in the fossa ovalis with minimal clinical presentation. A small mass was found occluding ...
