sp. nov: A new bacterium isolated from the toxic diatom.

sp. nov strain P2D13-UKM is a new species of Gram-positive bacteria isolated from a toxic diatom, . It is a halophilic aerobic, oxidase-negative, catalase-positive, circular, and colonies with white colour.

Insights into Nutrient Acquisition, Metabolism and Saxitoxin Biosynthesis through Comprehensive Transcriptome Survey.

The toxin-producing dinoflagellate is responsible for the outbreaks of harmful algae bloom (HABs). It is a widely distributed species and is responsible for producing paralytic shellfish poisoning toxins. However, the information associated with the environmental adaptation pathway and toxin biosynthesis in this species is still lacking.

Pathogenic hitchhiker diversity on international ships' ballast water at West Malaysia port.

This study investigates bacterial diversity and potential pathogens in the international ships' ballast water at Tanjung Pelepas Port, Malaysia, using 16S rRNA amplicon sequencing. Thirty-four bacterial phylum, 305 families, 577 genera, and 941 species were detected in eight ballast water samples of different origins. The similarity of the bacterial composition between samples was found to be random and not tied to geographical locations.

Characterization of putative pathogenic isolated from ballast water.

Background And Aim: is ubiquitous in marine-associated environments and has been increasingly recognized as a significant human pathogen that can cause serious infections mainly associated with exposure to seawater and ingestion of raw seafood. This study aimed to isolate and characterize from ballast water of ships berthed at Port Klang, Malaysia.

Materials And Methods: Ballast water was sampled from nine ships docked at Port Klang, Malaysia.

Biosynthesis of Saxitoxin in Marine Dinoflagellates: An Omics Perspective.

Saxitoxin is an alkaloid neurotoxin originally isolated from the clam in 1957. This group of neurotoxins is produced by several species of freshwater cyanobacteria and marine dinoflagellates. The saxitoxin biosynthesis pathway was described for the first time in the 1980s and, since then, it was studied in more than seven cyanobacterial genera, comprising 26 genes that form a cluster ranging from 25.
