Syntrophic relationships between algae and bacteria in a fresh-water stream and in culture /
… species of a pond community were isolated in axenic culture and tests were performed to determine the nature of mixed species interactions. Isolation procedures and field studies indicated that selected strains of Chlorella and Azotobacter were closely associated in their natural habitat. With …

Understanding The Mechanism and Extent of Vlse Recombination In Borrelia Burgdorferi Using Next-Generation Sequencing
… we were able to detect<em> vlsE</em> variants in axenic cultures of <em>B. burgdorferi</em> as well as co-cultures with mouse skin and heart tissues; these results were compared with those from mice infected for 7 days. Analysis of PacBio single molecule real-time (SMRT) sequencing indicated the …

The role of acid phosphatases in the phosphorus nutrition of arctic tundra plants
… sericeum) responded similarly to growth in axenic culture at 2 or 50 micromolar KH₂PO₄ or sodium inositol hexaphosphate: surface Vmax estimates were significantly greater for 2 micromolar- than for 50 micromolar-grown isolates. The presence of constitutive extracellular soluble phosphatase …

Purification and properties of some fresh water and marine cyanobacteria belonging to the orders Chamaesiphonales and Pleurocapsales
… and Pieurocapsales were isolated in axenic culture from marine and fresh water sources. Two strains isolated from fresh water, both assignable to the genus Chamaesiphon, are unicellular cyanobacteria which reproduce by budding; the buds being formed in succession at one pole of the …

The deterioration of concrete by heterothrophic bacteria and fungi
… activity of these organisms was compared with an axenic culture of Aspergillus carbonarius, since this fungus produces citric acid, a known deteriorative agent of concrete. Following the selection of these microorganisms, various conditions within the liquid culture medium were altered in an …

Survival and chemical control of Cylindrocladium spp. inciting root rot of black walnut seedlings
… phenomenon exists in nature. Germinability of axenic, laboratory-grown microsclerotia of C. crotalariae, C. floridanum, and C. scoparium incubated 4 wk at 6 C ranged from 0 to 91.3% (mean = 37.7%) of the initial germinability. Partial recovery of laboratory-grown microsclerotia from the …

Inquiries into the Mycobacterial Caseinolytic Protease System
… highly vulnerable and essential for growth in axenic culture and mouse models of infection. Due to the technical challenges associated with studying essential genes in mycobacteria, few bona-fide substrates of the Clp system have been identified. Furthermore, because of these challenges, …

Transcriptomic characterization of soybean – sclerotinia sclerotiorum interaction at early infection stages
… from AC and OxO to that of growth in liquid axenic culture. The comparison revealed dramatic differential transcriptomic responses at 4 and 8 hpi (with close to three thousand genes detected as significantly differentially expressed in leaves versus in culture), revealing a broad range of …

Transient heterologous protein expression in green microalgae
… protein expression. The baculovirus insect cell culture, yeast, and plants, such as Nicotiana benthamiana, are only a few of the commercial expression systems where this technology has been extensively used. These systems, however, often have disadvantages in terms of their cost, safety and …
