mikrobionellen

Mikrobionellen is a term used in ecology and microbiology to describe the collective community of microorganisms that inhabit a particular environment, and the interactions among them and with their substrate. The concept is closely related to, but not strictly identical with, microbiota or microbiome, and it emphasizes ecological relationships, energy flow, and nutrient cycling within a habitat. The mikrobionellen can include bacteria, archaea, fungi, protozoa, algae, and viruses, and may be free-living in soil, water, or sediment, or associated with hosts, plants, or surfaces. The composition of mikrobionellen varies with environmental conditions such as pH, temperature, moisture, nutrients, and disturbance, and is typically spatially structured.

Key roles of mikrobionellen include decomposition and the transformation of organic matter, cycling of carbon, nitrogen, sulfur, and phosphorus, and the maintenance of ecosystem productivity and resilience. In plant and animal systems, members of the mikrobionellen can form symbiotic relationships that enhance nutrient uptake, digestion, or immune defense, while other members may contribute to disease under certain conditions.

Studying mikrobionellen relies on culture-independent methods such as metagenomics, metatranscriptomics, and amplicon sequencing of marker genes, supplemented by microscopy and selective cultivation. These approaches reveal diversity, functional potential, and activity patterns that are often not apparent from the host perspective alone.

Understanding mikrobionellen is important for agriculture, environmental management, and human health, as disturbances to microbial communities can alter nutrient cycling, soil fertility, disease susceptibility, and bioremediation capacity.
