A family of microscopic freshwater EUKARYOTA, commonly known as golden algae. They share many features with the BROWN ALGAE but are planktonic rather than benthic. Though most are photosynthetic, they are not considered truly autotrophic since they can become facultatively heterotrophic in the absence of adequate light. In this state they can feed on BACTERIA or DIATOMS.

An island in the Lesser Antilles, one of the Windward Islands. Its capital is Fort-de-France. It was discovered by Columbus in 1502 and from its settlement in 1635 by the French it passed into and out of Dutch and British hands. It was made a French overseas department in 1946. One account of the name tells of native women on the shore calling "Madinina" as Columbus approached the island. The meaning was never discovered but was entered on early charts as Martinique, influenced by the name of St. Martin.

Succession and regulation factors of small eukaryote community composition in a lacustrine ecosystem (Lake Pavin). (1/15)

The structure and dynamics of small eukaryotes (cells with a diameter less than 5 microm) were studied over two consecutive years in an oligomesotrophic lake (Lake Pavin in France). Water samples were collected at 5 and 30 m below the surface; when the lake was stratified, these depths corresponded to the epilimnion and hypolimnion. Changes in small-eukaryote structure were analyzed using terminal restriction fragment length polymorphism (T-RFLP) and cloning and sequencing of the 18S rRNA genes. Terminal restriction fragments from clones were used to reveal the dominant taxa in T-RFLP profiles of the environmental samples. Spumella-like cells (Chrysophyceae) did not dominate the small eukaryote community identified by molecular techniques in lacustrine ecosystems. Small eukaryotes appeared to be dominated by heterotrophic cells, particularly Cercozoa, which represented nearly half of the identified phylotypes, followed by the Fungi-LKM11 group (25%), choanoflagellates (10.3%) and Chrysophyceae (8.9%). Bicosoecida, Cryptophyta, and ciliates represented less than 9% of the community studied. No seasonal reproducibility in temporal evolution of the small-eukaryote community was observed from 1 year to the next. The T-RFLP patterns were related to bottom-up (resources) and top-down (grazing) variables using canonical correspondence analysis. The results showed a strong top-down regulation of small eukaryotes by zooplankton, more exactly, by cladocerans at 5 m and copepods at 30 m. Among bottom-up factors, temperature had a significant effect at both depths. The concentrations of nitrogenous nutrients and total phosphorus also had an effect on small-eukaryote dynamics at 5 m, whereas bacterial abundance and dissolved oxygen played a more important structuring role in the deeper zone.  (+info)

Evidence for geographic isolation and signs of endemism within a protistan morphospecies. (2/15)

The possible existence of endemism among microorganisms resulting from and preserved by geographic isolation is one of the most controversial topics in microbial ecology. We isolated 31 strains of "Spumella-like" flagellates from remote sampling sites from all continents, including Antarctica. These and another 23 isolates from a former study were characterized morphologically and by small-subunit rRNA gene sequence analysis and tested for the maximum temperature tolerance. Only a minority of the Spumella morpho- and phylotypes from the geographically isolated Antarctic continent follow the worldwide trend of a linear correlation between ambient (air) temperature during strain isolation and heat tolerance of the isolates. A high percentage of the Antarctic isolates, but none of the isolates from locations on all other continents, were obligate psychrophilic, although some of the latter were isolated at low ambient temperatures. The drastic deviation of Antarctic representatives of Spumella from the global trend of temperature adaptation of this morphospecies provides strong evidence for geographic transport restriction of a microorganism; i.e., Antarctic protistan communities are less influenced by transport of protists to and from the Antarctic continent than by local adaptation, a subtle form of endemism.  (+info)

Chloroplast His-to-Asp signal transduction: a potential mechanism for plastid gene regulation in Heterosigma akashiwo (Raphidophyceae). (3/15)

BACKGROUND: Maintenance of homeostasis requires that an organism perceive selected physical and chemical signals within an informationally dense environment. Functionally, an organism uses a variety of signal transduction arrays to amplify and convert these perceived signals into appropriate gene transcriptional responses. These changes in gene expression serve to modify selective metabolic processes and thus optimize reproductive success. Here we analyze a chloroplast-encoded His-to-Asp signal transduction circuit in the stramenopile Heterosigma akashiwo (Hada) Hada ex Y. Hara et Chihara [syn. H. carterae (Hulburt) F.J.R. Taylor]. The presence, structure and putative function of this protein pair are discussed in the context of their evolutionary homologues. RESULTS: Bioinformatic analysis of the Heterosigma akashiwo chloroplast genome sequence revealed the presence of a single two-component His-to-Asp (designated Tsg1/Trg1) pair in this stramenopile (golden-brown alga). These data represent the first documentation of a His-to-Asp array in stramenopiles and counter previous reports suggesting that such regulatory proteins are lacking in this taxonomic cluster. Comparison of the 43 kDa H. akashiwo Tsg1 with bacterial sensor kinases showed that the algal protein exhibits a moderately maintained PAS motif in the sensor kinase domain as well as highly conserved H, N, G1 and F motifs within the histidine kinase ATP binding site. Molecular modelling of the 27 kDa H. akashiwo Trg1 regulator protein was consistent with a winged helix-turn-helix identity - a class of proteins that is known to impact gene expression at the level of transcription. The occurrence of Trg1 protein in actively growing H. akashiwo cells was verified by Western analysis. The presence of a PhoB-like RNA polymerase loop in Trg1 and its homologues in the red-algal lineage support the hypothesis that Trg1 and its homologues interact with a sigma 70 (sigma70) subunit (encoded by rpoD) of a eubacterial type polymerase. Sequence analysis of H. akashiwo rpoD showed this nuclear-encoded gene has a well-defined 4.2 domain, a region that augments RNA polymerase interaction with transcriptional regulatory proteins and also serves in -35 promoter recognition. The presence/loss of the His-to-Asp pairs in primary and secondary chloroplast lineages is assessed. CONCLUSION: His-to-Asp signal transduction components are found in most rhodophytic chloroplasts, as well as in their putative cyanobacterial progenitors. The evolutionary conservation of these proteins argues that they are important for the maintenance of chloroplast homeostasis. Our data suggest that chloroplast gene transcription may be impacted by the interaction of the His-to-Asp regulator protein (which is less frequently lost than the sensor protein) with the RNA polymerase sigma70 subunit.  (+info)

In Laguna Madre, Texas, USA, a monospecific brown tide bloom began in January 1990 and was still persisting at the time of this writing. Immediately following the start of the bloom, abundance, biomass and diversity of benthos declined, and have remained low for 6 yr. One explanation for the decline is that the brown tide organism is a poor food source. To determine whether the brown tide was incorporated into the estuarine food web, benthic invertebrates and fish were studied 14 mo after the bloom onset using stable carbon isotope ratios. Fish and benthos were collected from 2 areas, a seagrass habitat in Laguna Madre, and a muddy bottom habitat in the adjacent Alazan Bay. The muddy bottom fauna had a strong brown tide signature, indicating the incorporation of brown tide or brown tide detritus into the food web. The higher-biomass seagrass-fauna had heavier isotope values, reflecting incorporation of seagrass carbon in addition to brown tide. The top predators, Sciaenops ocellatus and Pogonias ...
As your question rightfully emphasizes - the optimizations of sample preparation (and handling) is crucially important for getting meaningful data from your single cell sequencing assay - if you dont have the cells going into the assay you will not be able to profile them. Worse yet, if you dont know you lost them, you could risk making a conclusion based on the composition of cells in the sample. In this case, you know what cells are important in your samples and are concerned that you may lose them in the processing. To assay whether your protocol is optimized for retention of a particular cell type, we usually recommend folks who have access to flow cytometry and a reliable flow panel to use this to identify the composition of cell types and their viability. This ends up being a strong indicator of what you will see in the single cell sequencing data. If you have other ways to mark the cells of interest, simple cell counting or qualitative assessments on a standard microscope are also ...
Mechanical micromanipulation is a classic method to isolate uncultivated microorganisms or early embryos, and it involves using a capillary pipette to suck up a single cell from a cell suspension with visual inspection of cellular morphology and coloring characteristics under a microscope [13, 14] (Fig. 1b). The drawback of mechanical micromanipulation is that it is low-throughput and time-consuming and can cause cellular injury from mechanical shearing during manipulation [15]. Additionally, it often leads to a failure for an unskilled manipulator or misidentification of the cellular morphology under the microscope.. FACS is the most efficient and economical method to isolate hundreds of thousands of individual cells per minute based on their size, granularity and fluorescence properties [4] (Fig. 1c). The high-throughput, time-saving and automatic properties are the main advantage of FACS. Additionally, it allows researchers to isolate specific individual cells from heterogeneous cell samples ...

Research Description. The liver is the primary filter for drugs, environmental toxins and chemicals and as such protects the body against harmful chemical exposures. This work will aid the differentiation, maturation and culture of hepatocytes in vitro. It will improve both the quality and quantity of hepatocytes for use in in-vitro toxicological screening of drugs and other compounds. Using Single Cell sequencing and WaveCrest, an algorithm that can minimize the Euclidian distance between the transcriptomes of the cells, we aim to spatially recreate the periportal to perivenous axis of the hepatocytes allowing us to understand region differences within the liver. Many toxins (such as acetaminophen) have a zone specific toxicity profile. By being blind to the zonation of hepatocytes on culture we could mischaracterize toxic compounds due to the fact that the sensitive population of cells might not be present in the culture.. ...

Algae have recently received much attention due to their potential as a source of clean biofuel. One of the key economic hurdles in the production of biofuel from algal feedstocks continues to be the harvesting process. Flocculation shows great potential for lowering the economic hurdle by providing a low energy, inexpensive method of separation. However, the mechanism of flocculation under varying environmental conditions is poorly understood. We aim to gain greater insight into the flocculation process by developing fundamental science-based models based on experimental measurements of floc formation and characteristics under a variety of environmental conditions (i.e., shear fields, flocculant addition, pH adjustment, etc.). Two critical conditions for flocculation with efficiencies above 90% with ferric chloride are identified for the freshwater alga Chlorella zofingiensis. First, a minimum amount of ferric chloride must be present in solution. The minimum amount of ferric chloride depends ...
The effects of CuCl2 and 12 Cu(II) complexes on reduction of chlorophyll content in statically cultivated green alga Chlorella vulgaris and inhibition of photosynthetic electron transport in spinach chloroplasts were studied.

29 gallon, FW... temp. high and Ram and plant sel.... algae-eater sel. 10/21/07 Hi, I have had the same 29 gallon aquarium since 1993 when I received it as a birthday gift from my dad when I was 12. Since that time I have evolved quite a bit in my knowledge of fish keeping! I recently moved, giving me the opportunity to completely overhaul my tank to become a planted aquarium. I purchased a 50 watt cable heater from Aquarium Designs (but it has no thermostat?!) which I sandwiched between a thick layer of sand on the bottom. I then spread a thin layer of Eco Completer, a thin layer of Fluorite, and finally mixed the rest of the two substrates with my original gravel to bring a good 5-6 layer for rooting. The problem is, with no thermostat, the water is a steady 84 degrees. Too bad 29 gallons is too small for Discus.? I started the cycle with black mollies, Cory catfish, and a Chinese algae eater (I hate them, but didnt want to buy another Pleco that would quickly outgrow the tank and uproot ...
Despite a number of studies to examine phylogeny, using one or several genes, the relationships of diatoms to other groups are still unclear and there is still a huge gap in our understanding of how and when diatoms acquired their unusual morphology and life-cycle characteristics. The diatoms have often been treated as a separate phylum, reflecting their unique features. Pascher (1914, 1921) suggested that the diatoms have features in common with the Chrysophyceae and Xanthophyceae and therefore placed these classes and the Bacillariophyceae in the phylum Chrysophyta. Ultrastructural and molecular sequence data have confirmed the general thrust of Paschers idea, placing the diatoms unambiguously among the heterokont protists (stramenopiles) within the chromalveolates (Adl et al. 2005). In the past, it was sometimes suggested that diatoms evolved well before their appearance in the fossil record and that the early phases in diatom evolution were lost long ago through diagenesis of diatomites ...
NASA is clearly looking far into the future for a way to handle both human waste and a need for fuel on either long space flights or when attempting to colonize another planet. To that end, theyve assigned life support engineer Jonathan Trent the task of coming up with a way to use algae to solve both problems at once. His solution is to use plastic bags floating in seawater as small bioreactors, containing wastewater, sunlight and carbon dioxide to grow algae that can be used as a means to create biofuel. Offshore Membrane Enclosures for Growing Algae (OMEGA) is an innovative method to grow algae, clean wastewater, capture carbon dioxide and ultimately produce biofuel. Using treated sewage as a growth medium, OMEGA would not compete with agriculture for water, fertilizer or land. NASAs OMEGA system consists of large flexible plastic tubes, called photobioreactors. Floating in seawater, the photobioreactors contain freshwater algae growing in wastewater. These algae are among the fastest

Algae eater, also called an algivore, is a common name for many bottom-dwelling or algae-eating species that feed on algae. Algae eaters are important for the fishkeeping hobby and many are commonly kept by hobbyists. Some of the common and most popular freshwater algae eaters in aquariums include:[1] ...
Accumulation and transformation of inorganic nanomaterials. As an example of inorganic granular biopersistent NMs, CeO2 NMs were shown to adsorb to phytoplankton, an important food source for marine organisms, within ,1 h of exposure at 0, 1, 2, and 3 mg L−1. Electrostatic attraction between the charged surfaces was assumed as a mechanism rather than active uptake or a chemical process.128 In a study performed with the freshwater algae Pseudokirchneriella subcapitata, up to 38% of the total cerium became directly associated with the cells during the 72 h exposure to concentrations between 15 and 200 μg L−1 polyacrylic acid stabilized CeO2. At the same time, the concentration of dissolved cerium in the exposure suspensions was very low (0.5-5.6 μg L−1), suggesting that toxicological effects derived from dissolved ions are minimal.129 Both results confirm an affinity of CeO2 for algal cells; however, this may depend on exposure concentration and particle modification. The freshwater ...
For trichloroethylene short term L(E)C50s from validated sources are reported for fish, invertebrates and algae. For fish the lowest 96-h LC50 from validated data is 16 mg/l found in marine species Limanda limanda (Pearson, 1975) and and 96-h LC of 28.3 mg/l in freshwater fish (Jordanella floridae) (Smith et al., 1985). The 48h IC50 for Daphnia magna is 20.8 mg/l (Hermens, 1984) which is the lowest acute toxicity value for freshwater invertebrates, for marine invertebrates the lowest 96-h LC50 is 14 mg/l in Americamysis bahia (Ward et al., 1986). For freshwater algae the lowest toxicity value was the 72h EC50 36.5 mg/l and an EC10 of 12.3 mg/l found in Chlamydomonas reinhardtii (Brack, 1994). In addition to short-term toxicity data, longer term toxicity data are reported for fish. A 10-day NOEC of 5.76 mg/l and a 28-day MATC of 14.85 mg/l are reported for the larvae and fry of Jordanella floridae (Smith et al., 1991). Although the study did not follow recognised testing protocols for chronic ...

Arthur Hill Hassall (13 December 1817, Teddington - 9 April 1894, San Remo) was a British physician, chemist and microscopist who is primarily known for his work in public health and food safety. Hassall was born in Middlesex as the youngest son of five children in a house of a surgeon. His father was Thomas Hassall (1771-1844) and his mother, née Ann Sherrock (c. 1778-1817).[1] He spent his school years in Richmond. He entered medicine through apprenticeship in 1834 to his uncle Sir James Murray (1788-1871), spending his early career in Dublin, where he also studied botany and the seashore.[2][3] In 1846 he published a two-volume study, The Microscopic Anatomy of the Human Body in Health and Disease, the first English textbook on the subject. After further studying botany at Kew and publishing on botanical topics, particularly freshwater algae, he came to public attention with his 1850 book A microscopical examination of the water supplied to the inhabitants of London and the suburban ...
Chlorella is a freshwater algae that is commonly supplemented by vegan populations (similar to Spirulina). Chlorella appears to be a bioavailable source of both Iron and Vitamin B12, and may have other benefits.
Background: Single Nucleotide Polymorphisms (SNPs) are widely used molecular markers, and their use has increased massively since the inception of Next Generation Sequencing (NGS) technologies, which allow detection of large numbers of SNPs at low cost. However, both NGS data and their analysis are error-prone, which can lead to the generation of false positive (FP) SNPs. We explored the relationship between FP SNPs and seven factors involved in mapping-based variant calling - quality of the reference sequence, read length, choice of mapper and variant caller, mapping stringency and filtering of SNPs by read mapping quality and read depth. This resulted in 576 possible factor level combinations. We used error- and variant-free simulated reads to ensure that every SNP found was indeed a false positive. Results: The variation in the number of FP SNPs generated ranged from 0 to 36,621 for the 120 million base pairs (Mbp) genome. All of the experimental factors tested had statistically significant ...

Heterosigma akashiwo and its related algae were re-examined by light and electron microscopes using cultured materials including type cultures of bothH. akashiwo andH. inlandica as well as specimens referred to asOlisthodiscus luteus maintained in CCAP and UTEX. All the strains examined were similar to one another in appearance and ultrastructural features. They can be accommodated in a single species,H. akashiwo, which has been invalidly published. In this paper, the genus is validly desribed by providing a Latin diagnosis and designating a type species. Ultrastructural characteristics are also given for the genus.

ABSTRACT: Spatiotemporal distributions of rare microbial taxa were examined in 384 samples from the Bermuda Atlantic Time-series Study (BATS) site, in the northwestern Sargasso Sea. Sequences were partitioned into 6 mutually exclusive sets based on abundance (abundant, rare, and very rare) and frequency of detection (frequent and infrequent). Analyses of variance for taxa that were frequently present, across all levels of abundance, demonstrated environmental filtering, indicating that gradients in environmental factors, such as season and depth, drive community assembly for rare taxa, as they do for abundant taxa. All abundant nodal taxonomic units (NTUs) had spatiotemporal periods of rarity, providing a clear demonstration of the role of fluctuating reproductive success in population dynamics, and the role of rare populations as seed banks. An inverse relationship between the number of rare taxa and physical stratification indicates that transport by mixing drives increased community diversity ...

The growing awareness of cardiac dysfunction by cancer treatment has led to the emerging field of Cardio-Oncology. However, there are no guidelines in terms of how to prevent and treat the new cardiotoxicity in cancer survivors due to the limited experimental assays. Dr. Cheng is a computational biologist by training, with expertise in analyzing, visualizing, and mining data from real world (e.g., electronic health records, and health care claims) and experiments that profile the molecular state of human cells and tissues by interactomics, transcriptomics, genomics, proteomics, and metabolomics for personalized drug discovery and precise patient care. The primary goal of Dr. Chengs lab is to combine tools from genomics, network medicine, bioinformatics, computational biology, chemical biology, and experimental pharmacology and systems biology assays (e.g., single cell sequencing and iPS-derived cardiomyocytes), to address the challenging questions toward understanding of various human complex ...
