Modern non-lithifying stromatolites (STs) on the shore of the volcanic lake Socompa in the Puna are affected by several extreme conditions. Although STs were proposed as ecologic models for understanding stress response and resilience in microbial ecosystems constituting a window into the past, our knowledge of ST function is still nascent. The present study assesses for the first time light utilization and functional metabolic stratification of STs on a millimeter scale through shotgun metagenomics. In addition, a scanning-electron-microscopy approach was used to explore the community. Our results demonstrated that Bacteroidetes and Cyanobacteria play major roles as ST builders and primary producers to sustain a diverse community of heterotrophs. STs manifest a high .

“…The mother cell divides into two daughter cells, which is similar to yeast (binary fission), and is common to most phytoplankton. For some species, the mother cell can also divide into more than two daughter cells via a process called multiple fission (Arakaki et al, 2013; Bišová & Zachleder, 2014; Jong et al, 2017; Kim et al, 2017; Reinecke et al, 2018; Sánchez‐Alvarez et al, 2017; Zachleder et al, 2021; Table 1). Both binary and multiple fission can even be observed in the same microalgae, either under different growth conditions (Bišová & Zachleder, 2014; Šetlík & Zachleder, 1984; Vítová & Zachleder, 2005; Zachleder et al, 2002) or at different phases of their cell cycle (Bišová & Zachleder, 2014; Oldenhof et al, 2006; Vítová, Bišová, Umysová, et al, 2011; Table 1).…”

Phytoplankton play an enormously important role in ecology and serve as critical food for aquatic organisms. The phytoplankton population rapidly increases in number after continuous cell cycles. Thus, understanding the cell cycle of phytoplankton is fundamental to the aquatic ecosystem research. The eukaryotic cell cycle has been clarified; however, unique characteristics exist in phytoplankton. Their cell cycle progression either differs among species or varies with environmental changes. Here, we review the cell cycle progression of the eukaryotic phytoplankton and its response to environmental factors, introduce the cell cycle research methods, highlight the identified cell cycle regulatory proteins, and discuss prospects for future research directions.

“…Since 2010, we have been screening several microalgal and cyanobacterial strains with advantageous characteristics of their cellular components for biotechnological applications ( Jeon et al, 2015 ; Kim et al, 2015a , b , 2017 ; Kim and Kang, 2016 ). Herein, we report the characterization of a unique indigenous strain of L. incisa isolated from a tidal flat in the Yellow Sea, Republic of Korea.…”

Microalgae are considered as sustainable resources for biofuel production. However, recently the focus on microalgal research has shifted toward the investigation of high-value metabolites for potential pharmaceutical and nutritional applications. Herein, we report the identification of a novel oleaginous green microalga isolated from the Yellow Sea in Korea. We also describe the morphological, molecular, and biochemical characteristics of this microalga. On the basis of microscopic and genetic analyses, the isolate was classified as Lobosphaera incisa (the strain was designated as K-1), and molecular phylogeny revealed that the isolate distinctly differed from the other known L. incisa strains. The microalga could be cultivated in various commercial culture media under a relatively broad range of pH and temperature conditions. We also did a rough and detailed estimation of the different cellular components in the microalga. The composition of arachidonic acid (C20:4ω6) in the lipids of L. incisa strain K-1 was relatively high, similar to that in other strains, however, the K-1 strain had higher proportions of the ω3 series of fatty acids (FAs), including α-linolenic acid (C18:3ω3) and eicosapentaenoic acid (C20:5ω3), highlighting its uniqueness and strong potential for biotechnological application. To the best of our knowledge, this is the first report on the isolation of L. incisa from Korea as well as from a marine environment; this novel strain might be useful for the production of high-value ω3 and ω6 polyunsaturated fatty acids (PUFAs).
