“…In the present study, we found that K. veneficum cells had lethal effects on brine shrimp nauplii and bivalve juveniles. The toxicities were similar to those of many toxic and harmful algae on brine shrimp nauplii and blood clam juveniles [55][56][57]. Our study demonstrated that the lethal effects of combined treatment with K. veneficum and surfactin on the nauplii and juveniles were significantly stronger than those of treatment with K. veneficum or surfactin alone, indicating that, while surfactin accelerated the killing of K. veneficum, it exhibited enhanced synergistic toxic effects on environmental organisms.…”

Biosurfactant has potential application value in the removal of microalgal blooms, but the ecological risks require more research. In this paper, the effects of surfactin on the toxic dinoflagellate Karlodinium veneficum were studied. The coaction of surfactin and K. veneficum was also evaluated through toxicological experiments on Artemia and juvenile clams. The results showed that: (1) in the concentration range of 0–10 mg/L, surfactin significantly killed algal cells in a dose-dependent manner within 48 h; the 24 h EC50 was 3.065 mg/L; (2) K. veneficum had the ability to restore population growth after stress reduction and the restored proliferation was positively correlated with the initial surfactin concentration; (3) the ability to restore population growth was associated with protection afforded by the promotion of antioxidant enzymes, including catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD), whose increase was positively correlated with the surfactin concentration; (4) the toxicity of the coculture of surfactin and K. veneficum was significantly greater than that of the K. veneficum culture or surfactin alone and was dose and time dependent. The potential ecological risks should be considered when applying biosurfactants, such as surfactin, in the removal of harmful algal blooms.

“…In the Kareniaceae, experiments conducted in vitro showed that Karenia brevis , K. mikimotoi , K. brevisulcata , K. concordia , K. armiger , K. veneficum , and Takayama sp. (as Gymnodinium type ’84 K in Japan) caused lethal effects to rotifer, brine shrimp, bivalve veliger, and fish larvae (Onoue et al 1985, Bergholtz et al 2005, Kubanek et al 2011, Shi et al 2012, Chang and Gall 2013, Yang et al 2018). Similar to these kareniaceans, the high lethality to invertebrates tested in this study suggests the ability of K. azanzae to produce bioactive substances responsible for their mortalities, although the lethality was not tested on fish larvae.…”

In all, 26 cultures of the harmful marine dinoflagellate Karlodinium, isolated from Japanese and Philippine coastal waters, were examined using LM, SEM, and molecular phylogeny inferred from ITS and LSU rDNA. Seven Karlodinium species (six from Japan and four from Philippines), K. australe, K. ballantinum, K. decipiens, K. gentienii, K. veneficum, K. zhouanum, and a novel species Karlodinium azanzae sp. nov., were identified based on their morphology and phylogenetic positions. Karlodinium azanzae from Manila Bay, Philippines was further characterized by TEM, HPLC (chloroplast pigment), and bioassay on brine shrimp and other marine zooplankton. Cells of K. azanzae were the largest (mean 25.3 µm long) in Karlodinium, possessed numerous tiny reflective particles, starch grains, and lipid granules, and usually swam at the bottom of the culture vessel. The straight apical structure complex and a ventral pore were common to the genus. The longitudinally elongated nucleus was located at the center, and the yellowish chloroplasts contained an embedded pyrenoid and carotenoid pigments typical of the genus (i.e., fucoxanthin as major carotenoid with its derivatives). TEM revealed a part of the flagellar apparatus, of which the long striated ventral connective is the first report in the Kareniaceae. Phylogenetic trees showed closest affinity of K. azanzae with K. australe and K. armiger. The new species could be differentiated from related species by cell size, position of the nucleus, and characteristic swimming behavior. Lethality of K. azanzae to large zooplankton and micropredation using a developed peduncle was also observed.

A phytoplankton bloom, dominated by the prymnesiophyte Chrysochromulina sp., developed in two areas of the red sea coast, Al-Nawras and Al-Arbaeen lagoons (Jeddah, Saudi Arabia) in the fall of October and December 2016. Chrysochromulina sp. dominated at total cell densities of average 3 × 10 6 cells.ml -1 , and have caused variable degrees of mortality in fish. Fish gills were examined under a microscope and showed the presence of Chrysochromulina sp cells. This study was conducted to investigate environmental factors that affect the growth characters as a function of different salinity, pH, temperature, and light-regime (light duration and intensity). Light-regime showed the highest effect among all the factors tested, at 10:14h L:D for the light duration with a growth rate of (0.352 μ.d -1 ), dry weight of (1552.601 ng), production per dry weight of (542.613 ng.d -1 ), and chlorophyll-a content (0.221µg.ml -1 ), as for light intensity, the best results were at around 60 to 70 µmol with a growth rate of (0.426 μ.d -1 ), dry weight of (2213.086 ng), production per dry weight of (929.419 ng.d -1 ), and chlorophyll-a content of (0.205 µg.ml -1 ). Other factors were best at 15°C, 40 PSU, and 7 to 8 for the temperature, salinity, and pH, respectively. No acute toxicity was present. Therefore, the fish mortality was most likely related to the morphological aspect of the isolated species by clogging of fish gills accompanied with suitable environmental conditions, grazing and a very low dissolved oxygen level in both lagoons.
