Environmental Condition for Producing Eggs of Rotifera Philodina erythrophthalma.

open access: yesJapanese Journal of Water Treatment Biology, 2000
The effect of mold, microbial pesticide Verticillium lecanii F126-12-3M on the egg-production of rotifera Philodina erythrophthalma, contributing to purification of wastewater was examined in batch culture experiment. The result indicated that the number of eggs was several times higher in the cultures with supernatant of mold than those of the control.

Seasonal status of density of phytoplanktons and zooplanktons in Gomti river of Lucknow (U.P.), India [PDF]

open access: yes, 2013
Biodiversity of river Gomti is heavily affected by pollution. Planktons are important biological parameters to access the pollution level. Zooplanktons are the source of food for higher organism and phytoplankton play important role in biosynthesis of ...

Exceptional in vivo catabolism of neurodegeneration-related aggregates

open access: yesActa Neuropathologica Communications, 2018
Neurodegenerative diseases are linked to a systemic enzyme resistance of toxic aggregated molecules and their pathological consequences. This paper presents a unique phenomenon that Philodina acuticornis, a bdelloid rotifer, is able to catabolize ...

Effect of increasing salinity on the acute toxicity of a commercial endosulfan formulation to the bdelloid rotifer Philodina acuticornis odiosa

open access: yes, 2011
Pesticides, such as endosulfan, can enter surface waters such as lakes and rivers, potentially posing an ecological risk. Rotifers are a dominant zooplankton species in many inland freshwater lakes in Australia; such lakes can also experience increased ...

Zooplankton grazing reduces the persistence of an anthropogenic pollution marker in lake water

open access: yesLimnology and Oceanography, Volume 69, Issue 8, Page 1870-1881, August 2024.
Abstract Wastewater treatment plant effluents release microbiological pollutants, including the intI1 gene (integrases of class 1 integron), which has been proposed as a target for monitoring anthropogenic pollution in surface waters. This gene correlates with antibiotic resistance genes, making it an important proxy for genetic contamination in ...

Low‐Molecular Weight Compounds that Extend the Chronological Lifespan of Yeasts, Saccharomyces cerevisiae, and Schizosaccharomyces pombe

open access: yesAdvanced Biology, Volume 8, Issue 5, May 2024.
Budding and fission yeasts are excellent model organisms for research on aging and lifespan regulation. Chronological lifespan, a definition of yeast lifespan, refers to the survival period of a cell population under nondividing conditions. In this review, the low‐molecular weight compounds are summarized that extend the chronological lifespan of ...
