| degradation capacities of bacteria and yeasts isolated from the gut of dendroctonus rhizophagus (curculionidae: scolytinae). | bark beetles (curculionidae: scolytinae) feed on the xylem and phloem of their host, which are composed of structural carbohydrates and organic compounds that are not easily degraded by the insects. some of these compounds might be hydrolyzed by digestive enzymes produced by microbes present in the gut of these insects. in this study, we evaluated the enzymatic capacity of bacteria (acinetobacter lwoffii, arthrobacter sp., pseudomonas putida, pseudomonas azotoformans, and rahnella sp.) and yeast ... | 2017 | 27544667 |
| temperature-dependent changes in the microbial storage flora of birch and spruce sawdust. | sawdust can be used to make pellets (biofuel) and particle boards and as a potential lignocellulose feedstock in bioethanol production. microbial activity can affect sawdust quality; hence, we monitored the microbial population in birch- and spruce sawdust after 3 months' storage at various temperatures. species composition was similar on both materials but was strongly influenced by temperature. bacteria were present on all materials at all conditions: on birch, 2.8 × 10(8) , 1.1 × 10(8) , and ... | 2014 | 24527731 |
| cytochrome p450 complement (cypome) of candida oregonensis, a gut-associated yeast of bark beetle, dendroctonus rhizophagus. | bark beetles (curculionidae: scolytinae) and associated microorganisms must overcome a complex tree's defence system, which includes toxic monoterpenes, to successfully complete their life cycle. a number of studies have suggested these microorganisms could have ecological roles related with the nutrition, detoxification, and semiochemical production. in particular, in filamentous fungi symbionts, cytochrome p450 (cyp) have been involved with terpenoid detoxification and biotransformation proces ... | 2016 | 27567714 |
| yeast diversity associated with invasive dendroctonus valens killing pinus tabuliformis in china using culturing and molecular methods. | bark beetle-associated yeasts are much less studied than filamentous fungi, yet they are also considered to play important roles in beetle nutrition, detoxification, and chemical communication. the red turpentine beetle, dendroctonus valens, an invasive bark beetle introduced from north america, became one of the most destructive pests in china, having killed more than 10 million pinus tabuliformis as well as other pine species. no investigation of yeasts associated with this bark beetle in its ... | 2014 | 24691849 |
