“…Under nutrient-replete conditions, allelochemicals released from Microcystis can suppress the nitrogen fixation of Dolichospermum and lead to cytotoxicity [ 21 ]. In co-culture experiments, the growth of Aphanizomenon was inhibited by some Microcystis strains, and this effect was caused by inducible unknown chemicals secreted by Microcystis [ 44 ]. A previous study also found that biological interactions probably contribute to a large proportion of the inter-annual variability of cyanobacterial bloom [ 23 ].…”

Harmful cyanobacterial blooms pose a risk to human health worldwide. To enhance understanding on the bloom-forming mechanism, the spatiotemporal changes in cyanobacterial diversity and composition in two eutrophic lakes (Erhai Lake and Lushui Reservoir) of China were investigated from 2010 to 2011 by high-throughput sequencing of environmental DNA. For each sample, 118 to 260 cpcBA-IGS operational taxonomic units (OTUs) were obtained. Fifty-two abundant OTUs were identified, which made up 95.2% of the total sequences and were clustered into nine cyanobacterial groups. Although the cyanobacterial communities of both lakes were mainly dominated by Microcystis, Erhai Lake had a higher cyanobacterial diversity. The abundance of mixed Nostocales species was lower than that of Microcystis, whereas Phormidium and Synechococcus were opportunistically dominant. The correlation between the occurrence frequency and relative abundance of OTUs was poorly fitted by the Sloan neutral model. Deterministic processes such as phosphorus availability were shown to have significant effects on the cyanobacterial community structure in Erhai Lake. In summary, the Microcystis-dominated cyanobacterial community was mainly affected by the deterministic process. Opportunistically dominant species have the potential to replace Microcystis and form blooms in eutrophic lakes, indicating the necessity to monitor these species for drinking water safety.

“…flos-aquae) belongs to order Nostocales and family Nostocaceae, which has a worldwide distribution (Rajaniemi et al 2005a). The species of genus Aphanizomenon and several of its members have been described as the cause for harmful bloom (Mcdonald and Lehman 2013;Ma et al 2015). Some species can produce hepatotoxic and neurotoxic, such as aphantoxin, anatoxin-a, cylindrospermopsin, and saxitoxin, cyanobacterial secondary metabolites which can cause critical problems (Paerl and Huisman 2009;Ballot et al 2010;Zhang et al 2015).…”

Morphology and taxonomy of the Aphanizomenon spp. (Cyanophyceae) and related species in the Nakdong River, South Korea

Background: The purpose of this study is to describe the morphological characteristics of the Aphanizomenon spp. and related species from the natural samples collected in the Nakdong River of South Korea. Aph. flos-aquae was similar to Aph. klebahnii, whereas these species differed from each other by the size and shape of fascicles, which was macroscopic in Aph. flos-aquae and microscopic in the Aph. klebahnii. One of their characteristics was that trichomes are easily disintegrating during microscopic examination. C. issatschenkoi could be clearly distinguished from other species by hair-shaped terminal cell. Its terminal cell was almost hyaline and markedly pointed. Young populations of the species without heterocytes run a risk of a misidentification. Aph. skujae was characterized by akinete. Morphological variability of akinetes from natural samples collected in the Nakdong River was rather smaller than those reported by previous study. Conclusions: C. issatschenkoi are described for the first time in the Nakdong River. In addition, Aph. klebahnii and Aph. skujae are new to South Korea.

“…Harmful algae blooms (HABs) have become a widespread concern in recent decades due to their frequent occurrence in eutrophic freshwater ecosystems [1][2]. Cyanobacterial blooms, especially of Microcystis aeruginosa, can cause serious water-quality problems in aquatic environments such as issues of oxygen depletion, aquaculture, drinking water supply, and recreational use [3][4][5].…”

Severe eutrophication and harmful cyanobacterial blooms of freshwater ecosystems has been a persistent environmental topic in recent decades. Allelochemical inhibition has received great attention in aquatic ecology and quality management. This study investigates the growth and full photosynthesis performance of pyrogallol on Microcystis aeruginosa TY001. The growth and pigment contents of M. aeruginosa were seriously inhibited by pyrogallol. The relative expression levels of the nblA gene were up-regulated under pyrogallol treatments. Unexpectedly, the relative transcript abundance of the psaB and psbA genes significantly increased compared with the control, but the chlorophyll fluorescence parameters of M. aeruginosa TY001 decreased significantly, except at 1 mg L -1 pyrogallol. In conclusion, the target sites of pyrogallol's toxic effect on the PSII of M. aeruginosa TY001 were mainly on the active reaction centers and the electron transport at the acceptor side.
