|May 1, 1979
Summary
Microorganisms, including Arthrobacter and Pseudomonas species, were found in spodumene deposits, aiding rock decomposition and element removal. This study highlights the significant role of microbial communities in geological processes.
Area of Science:
- Geomicrobiology
- Biogeochemistry
- Mineralogy
Context:
- Spodumene deposits contain diverse microbial communities.
- Microbial activity is observed in decomposition zones of spodumene, pegmatites, and shales.
- Aerobic, non-spore-forming bacteria dominate these environments.
Purpose:
- To identify microorganisms present in spodumene deposit environments.
- To investigate the role of these microorganisms in the decomposition of spodumene and associated rocks.
- To explore the potential of microbial communities in element removal from geological formations.
Summary:
- A broad range of heterotrophic and autotrophic microorganisms were identified in spodumene deposit decomposition zones.
- Predominant aerobic bacteria include Arthrobacter and Pseudomonas species, alongside specific groups like thionic, sulfate-reducing, and nitrifying bacteria.
- Spodumene and rock degradation were observed in moist, cracked areas, correlating with decreased pH, suggesting microbial involvement.
Impact:
- Provides insights into the geomicrobiological processes influencing spodumene and rock weathering.
- Suggests a potential role for microbial consortia in bioremediation and element extraction from mineral deposits.
- Highlights the interaction between microbial life and geological substrates in extreme environments.

02:33Phase Transitions: Sublimation and Deposition
20.2K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

01:02Role of Microtubules in Cell Wall Deposition
3.1K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...
