| nitrogen fixation by bacteria from the hindgut of termites. | anaerobically grown bacteria isolated from the hindgut contents of the termites coptotermes lacteus (froggatt), mastotermes darwiniensis froggatt and nasutitermes exitiosus (hill) were nitrogenase-positive as assayed by acetylene reduction. nitrogen fixation, confirmed with 15n2, was highest in the isolate from m. darwiniensis. all isolates were identified as citrobacter freundii (braak) werkman & gillen. | 1976 | 956782 |
| new endo-beta-1,4-glucanases from the parabasalian symbionts, pseudotrichonympha grassii and holomastigotoides mirabile of coptotermes termites. | abstract. an endo-beta-1,4-glucanase (eg) was purified from the hindgut of an australian mound-building termite, coptotermes lacteus. the hindgut extract had a peak separate from those for extracts obtained from the salivary glands and the midgut based on sephacryl s-200 gel chromatography, and also demonstrated an origin different from the endogenous egs of the termite itself. the recovery was further purified by sds-page, and its n-terminal amino acid sequence analyzed. this showed high homolo ... | 2002 | 12530528 |
| use of phage battery to investigate the actinofloral layers of termite gut microflora. | the termite gut microbiota can include a variety of micro-organisms from the three domains: bacteria, archaea and eucarya. the bacterial groups from the gut systems are mainly affiliated to the proteobacteria, the gram-positive groups bacterioiodes/flavobacterium branch and the spirochetes, firmicutes and actinobacteria. however, culture independent molecular studies have revealed that the majority of these microbial gut symbionts have not yet been cultured, including actinobacterial clusters as ... | 2007 | 17714406 |
| diversity of wolbachia in odontotermes spp. (termitidae) and coptotermes heimi (rhinotermitidae) using the multigene approach. | the intracellular bacteria, wolbachia, are well known for inducing reproductive alterations in arthropod hosts, especially insects. the ancient origin and huge diversity, combined with the ecological, biological and behavioral plasticity of termites, make the latter exciting candidates for studying the interactions of wolbachia. in the present study, we investigated the distribution of wolbachia in populations of odontotermes spp. and coptotermes heimi termites occurring in 14 colonies (12 odont ... | 2010 | 20402779 |
| the complete mitochondrial genome of coptotermes testaceus (isoptera: rhinotermitidae). | the complete circular mitochondrial genome (mitogenome) of coptotermes testaceus is 15 752bp in size, containing 37 typical genes and one non-coding at-rich region. the at content of the at-rich region is 68.3%. all protein coding genes (pcgs) start with standard atn initiation codons and end with complete termination codons taa or tag except for cox2, atp8, and nad5 genes using an incomplete stop codon t. trna genes are predicted with a characteristic cloverleaf secondary structure except for t ... | 2016 | 26242721 |
| toxicity, tunneling and feeding behavior of the termite, coptotermes vastator, in sand treated with oil of the physic nut, jatropha curcas. | oil of the physic nut, jatropha curcas l. (malpighiales: euphorbiaceae), was evaluated in the laboratory for its barrier and repellent activity against the philippine milk termite coptotermes vastator light (isoptera: rhinotermitidae). the study showed that j. curcas oil had anti-feeding effect, induced reduction in tunneling activity and increased mortality in c. vastator. behavior of termites exposed to sand treated with j. curcas oil indicated that it is toxic or repellent to c. vastator. tox ... | 2009 | 20053119 |
| eco-taxonomic insights into actinomycete symbionts of termites for discovery of novel bioactive compounds. | termites play a major role in foraging and degradation of plant biomass as well as cultivating bioactive microorganisms for their defense. current advances in "omics" sciences are revealing insights into function-related presence of these symbionts, and their related biosynthetic activities and genes identified in gut symbiotic bacteria might offer a significant potential for biotechnology and biodiscovery. actinomycetes have been the major producers of bioactive compounds with an extraordinary ... | 2015 | 24817085 |
| comparing mark-recapture and constant removal protocols for estimating forager population size of the subterranean termite coptotermes lacteus (isoptera: rhinotermitidae). | forager population sizes of colonies of coptotermes lacteus(froggatt) in new south wales were estimated using two methods: mark-recapture and constant removal, in two disturbed habitats: a pine plantation and cleared farmland. mark-recapture population estimates were unrealistic and unreliable: they could be improbably large, over 200 million foragers, and they varied enormously between samples for each colony without any pattern. the constant removal population estimates could also be unrealist ... | 2004 | 14972044 |
| tunnel specificity and forager movement in subterranean termites (isoptera: rhinotermitidae and termitidae). | the movement of foragers of two species of australian, subterranean, mound-building termites, coptotermes lacteus (froggatt) (rhinotermitidae) and nasutitermes exitiosus (hill) (termitidae), was investigated in their natural habitat using artificial feeding sites along trenches dug to mimic natural forager tunnels that radiate out from the central mound-nests. termites were dyed by self-feeding on cardboard soaked with histological fat-stains on one or two trenches and then termites were collect ... | 2002 | 12088536 |
