Respiration And Carbon Dioxide Accumulation In Soil Microcosms, Jasity Murphy
Respiration And Carbon Dioxide Accumulation In Soil Microcosms, Jasity Murphy
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
The thawing of permafrost leads to liberation of soil organic matter and microbial component resulting in significant effect on the carbon cycle. Changes in permafrost soils upon the global climate warming would significantly impact microbial soil activity. Currently, not a great deal is known about what happens to the microbial community after the permafrost thaws. The activity of microbial community was determined in microcosms experiment using respirometry. To assess the CO2 fluctuations during permafrost thawing a titration experiment was performed. Based on calculations using the respirometric equation it was found that CO2 production increases with temperature, core depth, …

Chemoorganotrophic Bacteria Isolated From Biodeteriorated Surfaces In Cave And Catacombs, Filomena De Leo, Agnese Iero, Gabrielle Zammit, Clara E. Urzi

The main objective of this work was the comparative analysis of a large number of bacterial strains isolated from biodeteriorated surfaces in three different sites, namely the catacombs of St. Callistus in Rome, Italy, the catacombs dedicated to St. Agatha in Rabat, Malta and the Cave of Bats in Zuheros, Spain. Our results showed that even considering only culturable chemoorganotrophic bacteria the variability is very high, reflecting the great variety of microhabitats present. Hence any strategies to prevent, control or eliminate the biofilm-embedded microbiota from an archeological surface should take into account a number of considerations as stipulated in our …

Bacterial diversity in sediments at UNESCO World Heritage listed Naracoorte Caves was surveyed as part of an investigation carried out in a larger study on assessing microbial diversity in caves. Cave selection was based on tourist accessibility; Stick Tomato and Alexandra Cave (> 15000 annual visits) and Strawhaven Cave was used as control (no tourist access). Microbial analysis showed that Bacillus was the most commonly detected microbial genus by culture dependent and independent survey of tourist accessible and inaccessible areas of show (tourist accessible) and control caves. Sediment bacterial groups were assigned to the Firmicutes, Actinobacteria and Proteobacteria. The survey …
