The Depositional Record, Volume 8, Issue 1, Page 165-209, February 2022., 2022 Three active travertine sites were investigated in Central Italy to identify the types of carbonate precipitates and the associated microbial mats at varying physico‐chemical parameters. This study confirms that microbial communities in hydrothermal settings vary as a function of water temperature.

Antimicrobial Agents Based on Metal Complexes: Present Situation and Future Prospects
International Journal of Biomaterials, Volume 2022, Issue 1, 2022., 2022 The rise in antimicrobial resistance is a cause of serious concern since the ages. Therefore, a dire need to explore new antimicrobial entities that can combat against the increasing threat of antibiotic resistance is realized. Studies have shown that the activity of the strongest antibiotics has reduced drastically against many microbes such as ...

Environmental Microbiology Reports, Volume 13, Issue 5, Page 708-719, October 2021., 2021 Summary Amoebae interact with bacteria in multifaceted ways. Amoeba predation can serve as a selective pressure for the development of bacterial virulence traits. Bacteria may also adapt to life inside amoebae, resulting in symbiotic relationships. Indeed, particular lineages of obligate bacterial endosymbionts have been found in different amoebae ...

The Important Role of Metal Ions for Survival of Francisella in Water within Amoeba Environment
BioMed Research International, Volume 2021, Issue 1, 2021., 2021 Francisella tularensis is a gram‐negative facultative intracellular bacterium that resists harsh environments. Several outbreaks of tularemia are linked to the consumption and contact with spring water. The number of F. tularensis in some waters is high, while in others, this bacterium does not survive.

The Cyst Wall Composition of Hartmannella glebae
Experimental Biology and Medicine, 1984 In this study cyst walls of Hartmannella glebae were isolated and quantitatively analyzed. They were fractionated into alkali-insoluble and alkali-soluble fractions. The alkali-insoluble fraction appeared to be cellulose which represented 4.2% of the total weight of the wall.

Lysosomal Activity and its Control in Encysting Hartmannella castellanii [PDF]
Journal of General Microbiology, 1969 SUMMARY: A latent, non-specific phosphatase of Hartmannella castellanii with an optimum pH of 4·0 has been investigated. The latency could be released in cell-free homogenates by treatment with Triton x 100, freezing and thawing, refrigeration or carbon tetrachloride.
