During colonial times they were renamed with the antillan word maguey. This was changed again by Carl von Linné who called them Agave (a greco-latin voice for admirable). For several Mexican prehispanic cultures, Agave species were not only considered as crops, but also part of their biocultural resources and cosmovision. Among the major products obtained from some Agave spp since pre-hispanic times is the alcoholic beverage called pulque or octli. -

Dissertation Implementing Organic Amendments To
DISSERTATION IMPLEMENTING ORGANIC AMENDMENTS TO ENHANCE MAIZE YIELD, SOIL MOISTURE, AND MICROBIAL NUTRIENT CYCLING IN TEMPERATE AGRICULTURE Submitted by Erika J. Foster Graduate Degree Program in Ecology In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Summer 2018 Doctoral Committee: Advisor: M. Francesca Cotrufo Louise Comas Charles Rhoades Matthew D. Wallenstein Copyright by Erika J. Foster 2018 All Rights Reserved i ABSTRACT IMPLEMENTING ORGANIC AMENDMENTS TO ENHANCE MAIZE YIELD, SOIL MOISTURE, AND MICROBIAL NUTRIENT CYCLING IN TEMPERATE AGRICULTURE To sustain agricultural production into the future, management should enhance natural biogeochemical cycling within the soil. Strategies to increase yield while reducing chemical fertilizer inputs and irrigation require robust research and development before widespread implementation. Current innovations in crop production use amendments such as manure and biochar charcoal to increase soil organic matter and improve soil structure, water, and nutrient content. Organic amendments also provide substrate and habitat for soil microorganisms that can play a key role cycling nutrients, improving nutrient availability for crops. Additional plant growth promoting bacteria can be incorporated into the soil as inocula to enhance soil nutrient cycling through mechanisms like phosphorus solubilization. Since microbial inoculation is highly effective under drought conditions, this technique pairs well in agricultural systems using limited irrigation to save water, particularly in semi-arid regions where climate change and population growth exacerbate water scarcity. The research in this dissertation examines synergistic techniques to reduce irrigation inputs, while building soil organic matter, and promoting natural microbial function to increase crop available nutrients. The research was conducted on conventional irrigated maize systems at the Agricultural Research Development and Education Center north of Fort Collins, CO. -

In Bangladesh the problem extends to rural drinking water wells, where non-biological solutions are not feasible. In serial enrichment cultures of water from various Bangladesh drinking water wells, we found transfer-persistent arsenite oxidation activity under four conditions (aerobic/anaerobic; heterotrophic/autotrophic). This suggests that biological decontamination may help ameliorate the problem. The enriched microbial communities were phylogenetically at least as diverse as the unenriched communities: they contained a bonanza of 16S rRNA gene sequences. These related to Hydrogenophaga, Acinetobacter, Dechloromonas, Comamonas, and Rhizobium/Agrobacterium species. In addition, the enriched microbiomes contained genes highly similar to the arsenite oxidase (aioA) gene of chemolithoautotrophic (e.g., Paracoccus sp. -

HEINZ SCHLESNER," CHRISTINA BARTELS, MANUEL SITTIG, MATTHIAS DORSCH, AND ERKO STACKEBRANDTT Institut fur Allgemeine Mikrobiologie, Christian-Albrecht-Universitat, 2300 Kiel, Federal Republic of Germany Four strains of budding, hyphal bacteria, which had very similar chemotaxonomic properties, were isolated from the Baltic Sea. The results of DNA-DNA hybridization experiments, indicated that three of the new isolates were closely related, while the fourth was only moderately related to the other three. Sequence signature and higher-order structural detail analyses of the 16s rRNA of strain IFAM 141gT (T = type strain) indicated that this isolate is related to the alpha subclass of the class Proteobacteriu. Although our isolates resemble members of the genera Hyphomicrobium and Hyphomonas in morphology, assignment to either of these genera was excluded on the basis of their markedly lower DNA guanine-plus-cytosine contents. We propose that these organisms should be placed in a new genus, Hirschiu baltica is the type species of this genus, and the type strain of H. bdtica is strain IFAM 1418 (= DSM 5838). Since the first description of a hyphal, budding bacterium, no1 and formamide were tested at concentrations of 0.02 and Hyphomicrobium vulgare (53), only the following additional 0.1% (vol/vol).

Etruscan tombs, many of which are subterranean, are one of the best representations of this culture. The principal importance of these tombs, however, lies in the wall paintings and in the tradition of rich burial, which was unique in the Mediterranean Basin, with the exception of Correspondence and Egypt. Relatively little information is available concerning the biodeterioration of Etruscan tombs, which is caused by a colonisation that covers the paintings with white, circular to irregular aggregates of bacteria or requests for materials biofilms that tend to connect each other. Thus, these colonisations sometimes cover extensive surfaces. Here should be addressed to we show that the colonisation of paintings in Tomba del Colle is primarily due to bacteria of the order C.S.-J. -

Swingley 1,* 1 Department of Biological Sciences, Northern Illinois University, DeKalb, IL 60115, USA 2 Centre for Microbiology and Environmental Systems Science, Division of Microbial Ecology, University of Vienna, 1090 Vienna, Austria 3 University of North Alabama, Florence, AL 35632, USA * Correspondence: [email protected]; Tel.: +1-209-777-4653 Received: 21 May 2019; Accepted: 21 June 2019; Published: 30 June 2019 Abstract: To date, a majority of studies of microbial life in hyperalkaline settings focus on environments that are also highly saline (haloalkaline). Haloalkaline conditions offer microbes abundant workarounds to maintain pH homeostasis, as salt ions can be exchanged for protons by dedicated antiporter proteins. Yet hyperalkaline freshwater systems also occur both naturally and anthropogenically, such as the slag fill aquifers around former Lake Calumet (Chicago, IL, USA). In this study, 16S rRNA gene sequences and metagenomic sequence libraries were collected to assess the taxonomic composition and functional potential of microbes present in these slag-polluted waterways. Relative 16S rRNA gene abundances in Calumet sediment and water samples describe community compositions not significantly divergent from those in nearby circumneutral conditions. Major differences in composition are mainly driven by Proteobacteria, primarily one sequence cluster closely related to Hydrogenophaga, which comprises up to 85% of 16S rRNA gene abundance in hyperalkaline surface sediments. Sequence identity indicates this novel species belongs to the recently established genus Serpentinomonas, a bacterial lineage associated with natural freshwater hyperalkaline serpentinizing springs. -

PhoD and PhoX alkaline phosphatases and AcpA acid phosphatase are produced by microorganisms in response to phosphorus limitation in the environment. In this thesis, the current knowledge of the prevalence of phoD and phoX in the environment and of their taxonomic distribution was assessed, and new molecular tools were developed to target the phoD and phoX alkaline phosphatase genes in soil microorganisms.
