    Notes: [Auszug] A symbiotic relationship between an insect and a species of bacterium with respect to the production of the insect's sex pheromone, has been found in the New Zealand grass grub beetle11 which carries a phenol-producing bacterium in the colleterial glands of the female. To our knowledge, however, ...

    Dimorphism in Ceratocystis minor var. barrasii (1977)
    Springer
    Mycopathologia 62 (1977), S. 179-182 
    Details
    ISSN: 1573-0832
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Ceratocystis minor var. barrasii, a fungus associated with the southern pine beetle, Dendroctonus frontalis, exhibits dimorphism which is influenced by the concentration of both carbon dioxide and phosphate. The mycelium produces blastospores from the tips and sides of its hyphae when the concentration of carbon dioxide is high, and these blastospores germinate if the concentration of phosphate is above about 10−2 mM, whereas below this concentration they bud.

    Relative numbers of selected bacterial forms in different regions of the cockroach hindgut (1981)

    Topics: Biology
    Notes: Abstract The relative numbers of fourteen microbial morphotypes in transmission electron micrographs of the hindgut of a cockroach, Eublaberus posticus, were counted and their distribution was analyzed statistically. The microbiota of three wall-associated regions (the anterior paunch, the posterior paunch, and the black band region) was clearly different from that of the gut lumen. The three wall fractions were also significantly different from each other. Only one of the fourteen types, prosthecate bacteria, appeared to be distributed randomly in the four fractions. The five main wall-associated morphotypes individually constituted up to 41% of the microbes in some micrographs. They included one type with the characteristic morphology of Methanospirillum. Six morphotypes rarely made up over 2% of the population, but were consistently present. The numbers of the remaining three morphotypes were quite variable between micrographs and between individual insects, but when present often made up 5–10% of the population.

    Microbial aspects of the cockroach hindgut (1984)
    Springer
    Archives of microbiology 138 (1984), S. 131-139 
    Details
    ISSN: 1432-072X
    Keywords: Hindgut microbiota ; Eublaberus posticus ; Poly-β-hydroxybutyrate ; Polyphosphate ; Metal ion deposition ; X-ray microprobe ; Methanogenesis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The cockroach hindgut has a complex, active microbiota, a large portion of which is associated with the chitinous gut wall. It provides a different environment from that of termites and other insects which are dependent on their hindgut microbiota for the digestion of cellulose. The pH of the midgut of Eublaberus posticus was not as high as it is in insects with a primarily cellulolytic nutrition. The hindgut of E. posticus was highly methanogenic, normal adults producing typically 10–25 μmol of methane per hour. The hindgut contained large amounts of the storage products polyphosphate and poly-β-hydroxybutyrate. Dilution series on nonselective medium yielded 100 times more obligately anaerobic colonies than facultatively anaerobic colonies. The most common facultative isolates were Klebsiella oxytoca, Citrobacter freundii and Enterobacter agglomerans. Treatment of E. posticus with metronidazole caused a dedifferentiation of the different regions of the hindgut. One region of the hindgut is characterized by its visibly black color, a unique microbiota, and electron dense deposits in electron micrographs. Chemical determinations showed high concentrations of ferrous and sulfide ions in the region. X-ray microprobe analysis showed that some of the electron dense deposits consisted of iron, sulfur and lower amounts of copper, aluminium, and chromium associated with ruthenium red staining material. Spectra of other deposits revealed only silicon, which was not associated with ruthenium red.

    Bark beetle pheromones: Production of verbenone by a mycangial fungus ofDendroctonus frontalis (1976)

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A mycangial symbiotic fungus ofDendroctonus frontalis is capable of oxidizingtrans-verbenol to verbenone. Both of these compounds are known to be important behavioral chemicals for this species, and it is suggested that development of the fungus in the plant host may play a role in influencing the behavior of the beetle to a successfully colonized tree.

    Fermentation of 1-hexadecene by Candida lipolytica (1969)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 11 (1969), S. 427-440

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Candida lipolytica, strain Phaff, was grown on 1.0% 1-hexadecene as sole source of carbon. Several oxidative intermediates were isolated and identified. Based on these intermediates two pathways are proposed for the degradation of the 1-alkene via the methyl group and the double bond. Subterminal oxidation of the 1-alkene was also indicated. Cell yield, lipid content, fatty acid profile and 1, 2-diol concentration are given for various rates of aeration during growth in a fermentor.
