  2. Soil microbiology - Wikipedia

    en.wikipedia.org/wiki/Soil_Microbiology

    A 2015 study analyzed a panel of Arabidopsis hormone mutants impaired in synthesis or signaling of individual or combinations of plant hormones, the microbial community in the soil adjacent to the root and in bacteria living within root tissue. Changes in salicylic acid signaling stimulated a reproducible shift in the relative abundance of ...

  3. Agricultural microbiology - Wikipedia

    en.wikipedia.org/wiki/Agricultural_microbiology

    Effective microorganisms enhance the soil's beneficial microbial community, paving the way for sustainable agriculture. These microorganisms consist of naturally occurring microbes, such as photosynthesizing bacteria, lactic acid bacteria, yeasts, and fermenting fungi, which can be applied to increase soil microbial diversity.

  4. Carbon-to-nitrogen ratio - Wikipedia

    en.wikipedia.org/wiki/Carbon-to-nitrogen_ratio

    In microbial communities like soil, the C:N ratio is a key indicator as it describes a balance between energetic foods (represented by carbon) and material to build protein with (represented by nitrogen). An optimal C:N ratio of around 24:1 provides for higher microbial activity. [16] [17]

  5. Microbial consortium - Wikipedia

    en.wikipedia.org/wiki/Microbial_consortium

    In 2020 Kang et al., using a strategy based on enrichment and dilution-to-extinction cultures, extracted from this original consortium (KMCG6) a simplified microbial consortia (SMC) with fewer species but similar keratinolytic activity. [23] Serial dilutions were performed on a keratinolytic microbial consortium pre-enriched from a soil sample.

  6. Soil food web - Wikipedia

    en.wikipedia.org/wiki/Soil_food_web

    Soil microbial communities are characterized in many different ways. The activity of microbes can be measured by their respiration and carbon dioxide release. The cellular components of microbes can be extracted from soil and genetically profiled, or microbial biomass can be calculated by weighing the soil before and after fumigation.

  7. Metagenomics - Wikipedia

    en.wikipedia.org/wiki/Metagenomics

    Metagenomic approaches to the analysis of complex microbial communities allow the targeted screening of enzymes with industrial applications in biofuel production, such as glycoside hydrolases. [84] Furthermore, knowledge of how these microbial communities function is required to control them, and metagenomics is a key tool in their understanding.

  8. Microbial ecology - Wikipedia

    en.wikipedia.org/wiki/Microbial_ecology

    Biotechnology may be used alongside microbial ecology to address a number of environmental and economic challenges. For example, molecular techniques such as community fingerprinting or metagenomics can be used to track changes in microbial communities over time or assess their biodiversity.

  9. Microbiota - Wikipedia

    en.wikipedia.org/wiki/Microbiota

    the ability to perform genomic and gene expression analyses of single cells and of entire microbial communities in the disciplines of metagenomics and metatranscriptomics [13] databases accessible to researchers across multiple disciplines [13] methods of mathematical analysis suitable for complex data sets [13]
