Journal of Sustainable Agriculture and Environment, Volume 1, Issue 1, Page 43-53, March 2022., 2022 Abstract Introduction Fungal plant pathogens are an emerging threat to economically important crop production worldwide and a significant risk to global food security. However, we have limited knowledge of how agricultural management practices drive the emergence and spread of pathogens within crop microbiomes and the underlying ecological mechanisms ...

New Phytologist, Volume 233, Issue 3, Page 1345-1357, February 2022., 2022 Summary Plants allocate resources to processes related to growth and enemy defence. Simultaneously, they interact with complex soil microbiomes that also affect plant performance. While the influence of individual microbial groups on single plants is increasingly studied, effects of microbial interactions on growth, defence and growth–defence ...

Cellular Microbiology, Volume 2022, Issue 1, 2022., 2022 The application of molecular techniques to accurately identify protozoan species can correct previous misidentifications based on traditional morphological identification. Colpodea ciliates have many toxicological and cytological applications, but their subtle morphological differences and small body size hinder species delineation. Herein, we used Cox

Biotechnology and Bioengineering, Volume 118, Issue 6, Page 2368-2379, June 2021., 2021 Indoor to outdoor transitions of algae cultivation is a challenging process. In this study, the authors investigated the effects of various parameters (light intensity, culture density and temperature) for scale‐up of a locally isolated Leptolyngbya sp. strain.

Functional Ecology of Two Contrasting Freshwater Ciliated Protists in Relation to Temperature
Journal of Eukaryotic Microbiology, Volume 68, Issue 1, January/February 2021., 2021 Abstract We conducted microcosm experiments with two contrasting freshwater ciliates on functional traits (FTs) related to their growth rate (numerical response, NR) and ingestion rate (functional response, FR) over a range of ecologically relevant temperatures.

PHOTOREACTIVATION IN COLPIDIUM COLPODA
The Biological Bulletin, 1952 1. Colpidium colpoda, grown on a single strain of bacteria (Pseudomonas ovalis) in 0.05% lettuce medium buffered at pH 7, was irradiated with various wave-lengths of monochromatic ultraviolet (UV) light. UV treatment produces a characteristic lag before beginning of fission and, following larger dosage, a characteristic decrease in division rate.

Growth kinetics of Colpoda steinii on Escherichia coli [PDF]
Applied and Environmental Microbiology, 1977 Colpoda steinii was grown in two-stage continuous cultures with Escherichia coli as prey species. The concentration of prey and the ciliate mean cell volume, dry weight, and number per milliliter were determined at known growth rates. Steady states were reached in the second-stage continuous cultures at all growth rates.

Assembly-history dynamics of a pitcher-plant protozoan community in experimental microcosms. [PDF]
PLoS ONE, 2012 History drives community assembly through differences both in density (density effects) and in the sequence in which species arrive (sequence effects).

Characterization of Chlorella vulgaris (Trebouxiophyceae) associated microbial communities1
Journal of Phycology, Volume 56, Issue 5, Page 1308-1322, October 2020., 2020 Microalgae exhibit extensive potential for counteracting imminent challenges in the nutraceutical, pharmaceutical, and biomaterial sectors, but lack economic viability. Biotechnological systems for contamination control could advance the economic viability of microalgal feedstock, but the selection of suitable strains that sustainably promote ...

A Multiscale CNN‐CRF Framework for Environmental Microorganism Image Segmentation
BioMed Research International, Volume 2020, Issue 1, 2020., 2020 To assist researchers to identify Environmental Microorganisms (EMs) effectively, a Multiscale CNN-CRF (MSCC) framework for the EM image segmentation is proposed in this paper. There are two parts in this framework: The first is a novel pixel‐level segmentation approach, using a newly introduced Convolutional Neural Network (CNN), namely, “mU‐Net‐B3 ...
