“…Cellulomonas species are known to be capable of electron transport chain phosphorylation in the presence of oxygen (aerobic respiration) and substrate level phosphorylation (fermentation) in its absence (Stackebrandt et al 2006). The energy yield is several times greater during aerobic respiration than during fermentation, thus explaining the lower amount of biomass produced in the absence of oxygen (Fig.…”

Microbially reduced iron minerals can reductively transform a variety of contaminants including heavy metals, radionuclides, chlorinated aliphatics, and nitroaromatics. A number of Cellulomonas spp. strains, including strain ES6, isolated from aquifer samples obtained at the U.S. Department of Energy's Hanford site in Washington, have been shown to be capable of reducing Cr(VI), TNT, natural organic matter, and soluble ferric iron [Fe(III)]. This research investigated the ability of Cellulomonas sp. strain ES6 to reduce solid phase and dissolved Fe(III) utilizing different carbon sources and various electron shuttling compounds. Results suggest that Fe(III) reduction by and growth of strain ES6 was dependent upon the type of electron donor, the form of iron present, and the presence of synthetic or natural organic matter, such as anthraquinone-2,6-disulfonate (AQDS) or humic substances. This research suggests that Cellulomonas sp. strain ES6 could play a significant role in metal reduction in the Hanford subsurface and that the choice of carbon source and organic matter addition can allow for independent control of growth and iron reduction activity.

“…The only cellulolytic facultative anaerobes reported to date are members of the genus Cellulomonas (Christopherson et al 2013; Lynd et al 2002; Stackebrandt 2006) and a few other taxa, including Actinotalea fermentans , formerly Cellulomonas fermentans (Yi et al 2007) and Caulobacter sp. FMC1 (Song et al 2013).…”

Aerobic and anaerobic cellulase production by Cellulomonas uda

2016

Cellulomonas uda (DSM 20108/ATCC 21399) is one of the few described cellulolytic facultative anaerobes. Based on these characteristics, we initiated a physiological study of C. uda with the aim to exploit it for cellulase production in simple bioreactors with no or sporadic aeration. Growth, cellulase activity and fermentation product formation were evaluated in different media under both aerobic and anaerobic conditions and in experiments where C. uda was exposed to alternating aerobic/anaerobic growth conditions. Here we show that C. uda behaves as a true facultative anaerobe when cultivated on soluble substrates such as glucose and cellobiose, but for reasons unknown cellulase activity is only induced under aerobic conditions on insoluble cellulosic substrates and not under anaerobic conditions. These findings enhance knowledge on the limited number of described facultative cellulolytic anaerobes, and in addition it greatly limits the utility of C. uda as an ‘easy to handle’ cellulase producer with low aeration demands.

“…The histopathology of 1 untreated and six treated mares and the resulting abortions, euthanized foetuses, or compromised foals were examined in these studies to determine the effect of oral exposure to processionary caterpillars. The treated mares were selected from the two experiments involving whole caterpillars and euthanized on sequential days of 2,4,8,10,12, and 24 from the first treatment. The euthanized foetuses, abortions, stillborn and compromised foals resulting from all three experiments were also examined.…”

Pathology of equine amnionitis and foetal lLoss: clinical and experimental studies

Detailed experience in identifying the appearance of setal fragments which is highlighted under toluidine blue staining allowed in depth examination of tissues from equine abortions submitted for examination in 2012. Five cases were found in which a caterpillar setal fragment was found in the allantochorion confirming that setal fragments migrate from field exposure as well as experimental exposure to processionary caterpillars.The experiments in this thesis have shown histologically for the first time, the ability of Processionary caterpillar setae to penetrate the maternal gut wall and migrate directly into the uterus and placental tissues. This is considered to be the most likely means of translocation of bacteria to the foetal membranes. The direct, rapid migration of setae in as little as two days from ingestion from the gut to the placenta facilitates bacterial infection.Bacteria present in the mare's gut likely attach to migrating setal fragments and translocate through the gut wall, the uterus and the foetal membranes in which they subsequently colonize. Incomplete migration of setal fragments may account for the focal mucoid placentitis induced when mares were exposed in early gestation. Bacterial colonization of 5 the foetal membranes and/or foetus may cause foetal compromise or death and eventual abortion.The variety of manifestations of EAFL due to the migration of setal fragments ranging from acute abortion, chronic active placentitis, stillbirth, compromised preterm and full term foals, and focal mucoid placentitis have a significant impact on the breeding of horses and ultimately the racing industry in Australia.6
