Top-down and bottom-up induced shifts in bacterial abundance, production and community composition in an experimentally divided humic lake

Abstract

We examined in situ abundance and activities of the major bacterial groups in the two most distinct compartments of experimentally divided Lake Grosse Fuchskuhle (Germany). The selected south-west (SW) and north-east basin (NE) differ substantially in their major chemical and biological parameters that potentially influence the dynamics and composition of microbial communities. Water from the basins were incubated in dialysis bags, which allowed for a relatively free exchange of nutrients, limiting solutes and low molecular organic matter but fully prevented exchange of organisms. To investigate the effect of top-down and bottom-up manipulations three size fractions of water samples were produced: (i) unfiltered, (ii) pre-filtered through 5.0 microm pore size membranes to remove large particles, as well as grazers and (iii) pre-filtered through 0.8 microm filters to remove all potential bacterivores. One set of dialysis bags was either incubated in acidic SW (rich in humic matter) or in almost neutral NE basin whereas a second set was transferred from the SW to the NE basin and vice versa. Our study revealed pronounced differences in growth rates among the major bacterial groups in relation to the treatments. Members of the Bet...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
