Ecological condition of seagrass meadows around sea-based tin mining activities in the waters of Bangka Belitung Islands, Indonesia.

Bangka Belitung islands have long been major tin producers, impacting the environment, including coastal ecosystems. Tin extraction from the seabed increases water turbidity and alters chemical composition, adversely affecting seagrass meadows. This study investigated the ecological condition of seagrass meadows around sea-based tin mining activities on the islands.

Two pathways regulate insulin-like growth factor genes in the brain and liver of the tropical damselfish Chrysiptera cyanea: A possible role for melatonin in the actions of growth and thyroid hormones.

External and internal factors are involved in controlling the growth of fishes. However, little is known about the mechanisms by which external factors trigger stimulus signals. This study explored the physiological roles of melatonin in the transcription of growth-related genes in the brain and liver of Chrysiptera cyanea, a tropical damselfish with long-day preference.

Antifungal strains and gene mapping of secondary metabolites in mangrove sediments from Semarang city and Karimunjawa islands, Indonesia.

Infection caused by pathogenic fungal species is one of the most challenging disease to be tackled today. The antifungal bacteria candidate can be found in terrestrial as well as aquatic ecosystems, with mangrove forests being one of them. The purpose of this study is to obtain candidate isolates of antifungal strains with a detection approach and gene mapping simulation of bioactive compounds producers and screening to determine qualitative antifungal activity.

Actinomycetes of secondary metabolite producers from mangrove sediments, Central Java, Indonesia.

Background And Aim: Actinomycetes are a group of Gram-positive bacteria with a fungus-like morphology. Their natural habitat encompasses terrestrial and water areas, including mangrove ecosystems. This study aimed to assess the and genes as the producers of secondary metabolites and to determine the target bacterial species using molecular DNA tests.

Sulfur-Containing Carotenoids from A Marine Coral Symbiont Strain KJ5.

strain KJ5 (formerly called sp. strain KJ5) is a yellowish marine bacterium that was isolated from a hard coral in the Karimunjawa Islands, Indonesia. The complete genome sequence of the bacterium has been reported recently.

Complete Genome Sequence of the Marine Bacterium Erythrobacter flavus Strain KJ5.

strain KJ5 (formerly called sp. strain KJ5) is a yellowish marine bacterium that was isolated from a hard coral in the Karimunjawa Islands of Indonesia. Here, we report the complete genome sequence of the bacterium and provide a useful resource for studies of the biosynthetic pathways of its unique carotenoids.
