There is increasing interest in the relationships between marine bacteria and red tide organisms. Some bacteria are known to kill red tide organisms, and may be responsible for accelerating the termination of red tides. Thus, certain algicidal bacteria have been proposed for the control of red tides. Meanwhile, many red tide organisms are known to feed on marine bacteria. The roles of marine bacteria and red tide organisms are therefore reversible. In Korean waters, the killing of red tide organisms by algicidal bacteria, and also the feeding of red tide organisms on marine bacteria have been extensively investigated. The findings of such studies may influence the conventional view of red tide dynamics, and also planktonic food webs. Here, we review the species and concentrations of algicidal bacteria that kill red tide organisms in Korean waters, as well as the ingestion rate and grazing impact of red tide organisms on marine bacteria. Furthermore, we offer an insight into the ecological roles of these 2 components in marine planktonic food webs.

In recent years, interest in algicidal bacteria has risen due to their ecological importance and their potential as biotic regulators of harmful algal blooms. Algicidal bacteria shape the plankton communities of the oceans by inhibiting or lysing microalgae and by consuming the released nutrients. Kordia algicida strain OT‐1 is a model marine algicidal bacterium that was isolated from a bloom of the diatom Skeletonema costatum. Previous work has suggested that algicidal activity is mediated by secreted proteases. Here, we utilize a transcriptomics‐guided approach to identify the serine protease gene KAOT1_RS09515, hereby named alpA1 as a key element in the algicidal activity of K. algicida. The protease AlpA1 was expressed and purified from a heterologous host and used in in vitro bioassays to validate its activity. We also show that K. algicida is the only algicidal species within a group of four members of the Kordia genus. The identification of this algicidal protease opens the possibility of real‐time monitoring of the ecological impact of algicidal bacteria in natural phytoplankton blooms.

A bacterial strain designated antisso-27(T), previously isolated from saltpan in Taiwan while screening for bacteria for algicidal activity, was characterized using the polyphasic taxonomic approach. Strain antisso-27(T) was Gram-negative, aerobic, brownish yellow colored, rod-shaped, non-flagellated and non-gliding. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain antisso-27(T) belonged to the genus Aquimarina within the family Flavobacteriaceae with relatively low sequence similarities of 94.0-96.6% to other valid Aquimarina spp. It contained iso-C(17:0) 3-OH, iso-C(15:0), iso-C(16:0), iso-C(15:1) and iso-C(15:0) 3-OH as the main fatty acids and contained a menaquinone with six isoprene units (MK-6) as the major isoprenoid quinone. Major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, an uncharacterized aminolipid and five uncharacterized phospholipids. Strain antisso-27(T) employed direct mode of algicidal lysis to Chlorella vulgaris strain 211-31; nevertheless, it released an algicidal substance against M. aeruginosa strain MTY01. This is the first study that the Aquimarina species possesses both direct and indirect algicidal activities. On the basis of the phylogenetic and phenotypic data, strain antisso-27(T) should be classified as representing a novel species, for which the name A. salinaria sp. nov. is proposed. The type strain is A. salinaria antisso-27(T) (= BCRC 80080(T) = LMG 25375(T)).
