Microbe-Plant Interactions
140
Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Microbial Corrosion
93
Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

Biodeterioration
86
Biodeterioration refers to the unwanted alteration of materials caused by microorganisms—especially fungi—which damage both organic substrates (paper, wood, textiles) and inorganic ones (stone, plaster, glass). Unlike abiotic decay, biodeterioration results from biological activity that produces physical disruption and chemical degradation.Physical deterioration occurs as fungal hyphae penetrate pores, cracks, and surface irregularities. Hyphal turgor pressure, thigmotropic growth...

Production of Biopesticides
108
Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
