Hollow-Fiber Membrane Chamber as a Device for In Situ Environmental Cultivation [PDF]

open access: yesApplied and Environmental Microbiology, 2009
ABSTRACT A hollow-fiber membrane chamber (HFMC) was developed as an in situ cultivation device for environmental microorganisms. The HFMC system consists of 48 to 96 pieces of porous hollow-fiber membrane connected with injectors. The system allows rapid exchange of chemical compounds, thereby simulating a natural environment.

Application of culturomics in fungal isolation from mangrove sediments

open access: yesMicrobiome, 2023
Background Fungi play a crucial role in ecosystems, and they have been widely considered a promising source for natural compounds that are crucial for drug discovery. Fungi have a high diversity, but about 95% of them remain unknown to science.

The Seed Traits Associated with Dormancy and Germination of Herbaceous Peonies, Focusing on Species Native in Serbia and China

open access: yesHorticulturae, 2022
Even though peonies are highly valued as ornamental, medicinal, and edible species and are also considered to be long-lived and relatively disease and pest resistant, they are becoming rare or endangered in their natural habitats. This could be primarily

IN SITU AND EX SITU FOLIAR RESPONSE REACTIONS OF SPONTANEOUS AND CULTIVATED TAXA OF THE GENUS TAXUS L.

open access: yesCarpathian Journal of Earth and Environmental Sciences, 2023
Photosynthesis, the process by which green plants synthesize carbohydrates from the carbon dioxide available in the environment using light energy as a fixed energy source with the help of photoassimilate pigments, underlies all food chains in nature.

Phylogenetic identification and in situ detection of individual microbial cells without cultivation [PDF]

open access: yesMicrobiological Reviews, 1995
The frequent discrepancy between direct microscopic counts and numbers of culturable bacteria from environmental samples is just one of several indications that we currently know only a minor part of the diversity of microorganisms in nature. A combination of direct retrieval of rRNA sequences and whole-cell oligonucleotide probing can be used to ...

Functional gene-guided enrichment plus in situ microsphere cultivation enables isolation of new crucial ureolytic bacteria from the rumen of cattle

open access: yesMicrobiome, 2023
Background Ruminants can utilize urea as a dietary nitrogen source owing to their ability to recycle urea-N back to the rumen where numerous ureolytic bacteria hydrolyze urea into ammonia, which is used by numerous bacteria as their nitrogen source ...

An in situ method for cultivating microorganisms using a double encapsulation technique. [PDF]

open access: yesFEMS microbiology ecology, 2009
The lack of cultured microorganisms represents a bottleneck for advancement in microbiology. The development of novel culturing techniques is, therefore, a crucial step in our understanding of microbial diversity in general, and the role of such diversity in the environment, in particular.
