benzoic acid-degrading bacteria from the intestinal tract of macrotermes michaelseni sjöstedt.the intestinal tracts of termites host a wide variety of microbial symbionts, which have been implicated in degradative processes. in this study, a fungus-cultivating termite, macrotermes michaelseni was found to harbor 2.2 x 10(6) bacterial cells per ml of gut homogenates capable of degrading benzoic acid. two benzoic acid degrading bacteria were isolated from the highest dilution of gut homogenates in oxic media with benzoic acid as the sole carbon source. isolate cbc was related to stenotroph ...200717304624
454 pyrosequencing-based assessment of bacterial diversity and community structure in termite guts, mounds and surrounding soils.termites constitute part of diverse and economically important termite fauna in africa, but information on gut microbiota and their associated soil microbiome is still inadequate. in this study, we assessed and compared the bacterial diversity and community structure between termites' gut, their mounds and surrounding soil using the 454 pyrosequencing-based analysis of 16s rrna gene sequences. a wood-feeder termite (microcerotermes sp.), three fungus-cultivating termites (macrotermes michaelseni ...201526355944
comparison of volatile blends and nucleotide sequences of two beauveria bassiana isolates of different virulence and repellency towards the termite macrotermes michealseni.isolates of the fungus beauveria bassiana have different levels of virulence and repellency against the termite macrotermes michaelseni. in the present study, we compared the volatile profiles and gene sequences of two isolates of the fungus with different levels of virulence and repellence to the termite. gas chromatography-mass spectrometric analyses showed quantitative and qualitative differences in the composition of volatiles of the two isolates. the repellencies of synthetic blends of 10 p ...201323111683
comparison of volatile blends and gene sequences of two isolates of metarhizium anisopliae of different virulence and repellency toward the termite macrotermes michaelseni.previously, we reported an interesting relationship between virulence and repellency of different isolates of the fungus metarhizium anisopliae towards the termite macrotermes michaelseni: the higher the virulence of a given isolate, the greater its repellency. in the present study, we compared the volatile profiles of two isolates, one that was more virulent (and repellent) and one that was less virulent (and repellent) to the termite. the prominent components of the two blends were characteriz ...201121346123
relationship between virulence and repellency of entomopathogenic isolates of metarhizium anisopliae and beauveria bassiana to the termite macrotermes michaelseni.termites encounter a diverse array of potentially useful and harmful fungi in their subterranean habitats. these vary from symbiotic to harmful species with varying levels of virulence. how these hemiedaphic insects survive in habitats with infective fungi is not well understood. possible mediation of olfactory signals in avoiding contact with entomopathogenic fungi has been explored by a number of workers. in the present study, we initially found that macrotermes michaelseni detected a virulent ...200919442668
