Metatranscriptomics is the set of techniques used to study gene expression of microbes within natural environments, i.e., the metatranscriptome. [1]While metagenomics focuses on studying the genomic content and on identifying which microbes are present within a community, metatranscriptomics can be used to study the diversity of the active genes within such community, to quantify their ...
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 ...
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.
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.
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.
Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface.
[7] [8] [9] Microorganisms (soil microbes) are involved in biogeochemical cycles in the soil which helps in fixing nutrients, such as nitrogen, phosphorus and sulphur in the soil (environment). [10] As a consequence of the quantitative magnitude of microbial life (calculated as 5.0 × 10 30 cells, [ 11 ] [ 12 ] ) microbes, by virtue of their ...
