Environmental Applications of Microorganisms

78
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Bioremediation00:46

Bioremediation

19.2K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Microbial Nutrition

117
Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Microorganisms in Agriculture and Food industry

103
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Area of Science:

  • Environmental Microbiology
  • Biotechnology
  • Metallurgy

Background:

  • Biohydrometallurgy faces limitations in efficiency and selectivity for e-waste management.
  • Novel microbial strains with high toxicity tolerance and bioleaching capabilities are needed for improved e-waste processing.

Purpose of the Study:

  • To explore the bioleaching potential of the indigenous Bacillus sporothermodurans ISO1 strain.
  • To optimize culture variables for enhanced bio-cyanide production and metal leaching.
  • To investigate a chemo-biohydrometallurgy approach for improved metal recovery from e-waste.

Main Methods:

  • Isolation and characterization of Bacillus sporothermodurans ISO1 from a metal-habituated site.
  • Optimization of culture variables (temperature, pH, glycine, pulp density) using One Factor at a Time (OFAT) and Response Surface Methodology (RSM).
  • Sequential leaching using ferric chloride followed by bio-cyanidation for chemo-biohydrometallurgy.

Main Results:

  • Optimized conditions yielded 95% Cu and 44% Ag recovery using RSM.
  • Bacillus sporothermodurans ISO1 demonstrated high toxicity tolerance (EC50 = 425 g/L).
  • Chemo-biohydrometallurgy approach improved leaching of Ag (57%), Au (67%), and Pt (60%).

Conclusions:

  • Bacillus sporothermodurans ISO1 is a promising candidate for large-scale bioleaching of e-waste.
  • The developed chemo-biohydrometallurgy approach enhances the recovery of multiple valuable metals.
  • This research contributes to sustainable development goals through urban mining and effective e-waste treatment.
