Phylogenetic analyses and diterpenoid production by marine bacteria of the genus Saprospira

Abstract

The relationship between 16S rRNA gene sequence-derived phylogeny and the bacterial production of diterpenoids from 18 isolates of marine bacteria belonging to the genus Saprospira was determined. Restriction fragment length polymorphism (RFLP) analysis of the PCR amplified 16S rRNA genes of these isolates indicated four distinct phylotypes. The terpenoid metabolite profiles of each phylotype, determined by liquid chromatography mass spectrometry (LCMS) and nuclear magnetic resonance (NMR) analyses, indicated that diterpenoid production was restricted to phylotype A, which included the type specimen S. grandis Gross, and the sole member of the closely related phylotype B. The discovery of two new neoverrucosane diterpenoids produced by phylotype B has also been documented.

2025-2026 B.A.M. Student Voices

Throughout the Bahamas Awareness of Mangroves (B.A.M.) and Jamaica Awareness of Mangroves in Nature (J.A.M.I.N.) programs, we evaluate each phase of the mangrove education and restoration process to better understand how students are learning, growing, and connecting with their coastal environments.

Before the programs begin, students share what they already know about mangroves and how they feel about them. As the program progresses, we continue to gather feedback to see how their knowledge evolves from identifying mangrove species and understanding food webs to recognizing the role mangroves play in coastal protection and climate change mitigation.

But the surveys go beyond science content.

We also ask students…

Ten Years of B.A.M.: Rooted in Partnership, Growing in Purpose

Ten years ago, the Bahamas Awareness of Mangroves (B.A.M.) program began with a simple but meaningful commitment: to connect Bahamian students with the mangrove ecosystems that shape and protect their island home.

Since 2015, B.A.M. has been implemented in partnership with Friends of the Environment, whose dedication to environmental stewardship in Abaco has made this program possible year after year. Together, we have worked alongside Patrick J. Bethel High School and Forest Heights Academy to bring hands-on mangrove science into classrooms and out into the field.

What makes ten years remarkable is not just longevity — it is consistency…
