Induction and ultrastructure for cysts of Azotobacter

浙江大学学报. 农业与生命科学版, 2001
Within 5 days of induction with n-butanol medium, 98%vegetative cells of Azotobacter vinelandii gave rise to cysts. 91% vegetative cells of Azotobacter chroococcus were converted to cysts. The cysts were spheroids or elliptical whose axe is 1.2 pm to 1.5

What Drives the Changing Characteristics of Plankton in Floodplain Lakes: Season, Environmental Factors, or Lake Characteristics?

Ecology and Evolution, Volume 16, Issue 9, September 2026.
In this study, we conducted investigations and monitoring on lakes during the wet season and dry season. We studied the structure, taxonomic/functional diversity, community assembly, and niche differentiation of plankton communities, analyzed the biogeographical patterns of plankton communities, and explored the driving factors affecting plankton ...

Statistical filtering to aid in the sorting of phytoplankton: The effects of image library size and phytoplankton shape

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract The demand for efficient image sorting methods has increased due to technological advancements that enable more intensive phytoplankton monitoring. Both statistical and machine learning algorithms can misidentify algal taxa in taxonomically diverse samples, in which phytoplankton morphology and image traits can vary.
