Abstract Microbial carbon use efficiency (CUE)—the balance between microbial growth and respiration—strongly impacts mediated soil storage is sensitive to many well-studied abiotic environmental factors. However, surprisingly, little work has examined how biotic interactions in may impact CUE. Here, we review the theoretical empirical lines of evidence exploring affect CUE through lens life history strategies. Fundamentally, a population constrained by density carrying capacity, which, when reached, causes species grow more quickly less efficiently. When microbes engage interspecific competition, they accelerate rates acquire limited resources release secondary chemicals toxic competitors. Such processes are not anabolic thus constrain In turn, antagonists activate one number stress responses that also do involve biomass production, potentially further reducing contrast, facilitation can increase expanding realized niches, mitigating production costs extracellular enzymes. at higher trophic levels influence For instance, predation on positively or negatively changing outcomes competition. Finally, discuss plants select for efficient under different contexts. short, this demonstrates potential be strong regulator additionally provides blueprint future research address key knowledge gaps ecological applied importance sequestration.

Because of their uncontrolled proliferation, biofilm-based diseases pose severe hazards to human life. Biofilm production makes the immune system resistant antibiotics, emphasizing need prevention in health. When pathogenic bacteria and fungi are injected into people, they develop biofilms cause waterborne illnesses. Understanding methods by which these arise is thus critical for creating techniques removing them from water systems. This overview introduces biofilms, highlighting adhesion detachment phenomena growth basics. Following that, stability drinking distribution systems (DWDS) influence on living organisms explored. review focuses biofilm treatment such as ultrasound, photothermal photodynamic methods, microbubbles, chemical approaches (via nanomaterials). The following section delves most recent physical prevent development, chloramine—a stable utilized DWDS suppress microbial growth—and its decay kinetics. Finally, future study goals recommendations chloramine a viable limiting development presented.

Summary Plants and microbes have evolved sophisticated ways to communicate coexist. The simplest interactions that occur in plant‐associated habitats, i.e., those involved disease detection, depend on the production of microbial pathogenic virulence factors host's immunological response. In contrast, can also be beneficial for their host plants a number ways, including fighting pathogens promoting plant growth. order clarify mechanisms directly these various plant–microbe interactions, we must still deepen our understanding how interkingdom communication systems, which are constantly modulated by resident activity, established and, most importantly, effects span physically separated compartments. Efforts this direction revealed complex interconnected network molecules associated metabolic pathways modulate microbe–microbe regulate diverse ecological responses. Once sufficiently understood, will biotechnologically exploitable, example, use sustainable agriculture. aim review is present latest findings dazzlingly arsenal efficiently mediate specific microbe–plant during development different organs.

Summary Autotrophic carbon dioxide (CO 2 ) fixation by microbes is ubiquitous in the environment and potentially contributes to soil organic (SOC) pool. However, multiple autotrophic pathways of microbial assimilation paddy soils remain poorly characterized.

ABSTRACT Biogeochemical models for predicting carbon dynamics increasingly include microbial processes, reflecting the importance of microorganisms in regulating movement between soils and atmosphere. Soil viruses can redirect among various chemical pools, indicating a need quantification development soil that explicitly represent viral dynamics. In this opinion, we derive global estimate potentially released from biomass by infections synthesize quantitative budget existing literature includes impacts. We then adapt known mechanisms which influence cycles marine ecosystems into soil‐explicit framework. Finally, explore diversity virus–host interactions during infection conceptualize how mode may impact fate. Our synthesis highlights key knowledge gaps hindering incorporation cycling research generates specific hypotheses to test pursuit better quantifying explain ecosystem‐scale fluxes. The identifying critical drivers behind dynamics, including these elusive but likely pervasive redistribution, becomes more pressing with climate change.
