An Overview of Tracer Applications in the Upstream Petroleum Industry: A Focus on Enhanced Oil Recovery

open access: yesInternational Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.
Tracers, recognized as vital technologies, enable precise monitoring of production processes, particularly in the context of enhanced oil recovery (EOR) projects. This study emphasizes tracers’ necessity as auxiliary tools for understanding reservoir characteristics, contributing to improved well productivity, reduced water production rates, and ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Biosynthesis of the Stress-Protectant and Chemical Chaperon Ectoine: Biochemistry of the Transaminase EctB

open access: yesFrontiers in Microbiology, 2019
Bacteria frequently adapt to high osmolarity surroundings through the accumulation of compatible solutes. Ectoine is a prominent member of these types of stress protectants and is produced via an evolutionarily conserved biosynthetic pathway beginning ...

Model‐Guided Systematic Metabolic Engineering for Enhanced Spinosad Biosynthesis in Saccharopolyspora spinosa NHF132

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
A genome‐scale model guided the systematic metabolic engineering of Saccharopolyspora spinosa, enabling a 5.5‐fold boost in the green bioinsecticide spinosad to 1.8 g L−1 and establishing an actinomycete framework for complex natural products overproduction.

Diverse and Abundant Secondary Metabolism Biosynthetic Gene Clusters in the Genomes of Marine Sponge Derived Streptomyces spp. Isolates [PDF]

open access: yes, 2018
The genus Streptomyces produces secondary metabolic compounds that are rich in biological activity. Many of these compounds are genetically encoded by large secondary metabolism biosynthetic gene clusters (smBGCs) such as polyketide synthases (PKS) and ...

Genomic and Metabolic Characterization of a Potentially Novel Paenibacillus Species Isolated as a Laboratory Contaminant Growing on Medium Supporting Cotton Tissue Culture

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
This study explores the genomic and metabolic characterization of a potentially novel Paenibacillus species isolated from cotton plant tissues. Phylogenetic analysis based on multi‐locus sequence data from six conserved genes reveals that Paenibacillus sp. TAB_01 forms a distinct lineage among 19 Paenibacillus species. Paenibacillus sp.

Ectoine, from a Natural Bacteria Protectant to a New Treatment of Dry Eye Disease

open access: yesPharmaceutics
Ectoine, a novel natural osmoprotectant, protects bacteria living in extreme environments. This study aimed to explore the therapeutic effect of ectoine for dry eye disease. An experimental dry eye model was created in C57BL/6 mice exposed to desiccating

Developing High‐Efficiency Electroporation Protocols for Hard‐To‐Transform Halomonas spp.

open access: yesMicrobial Biotechnology, Volume 18, Issue 12, December 2025.
Genetic manipulation of Halomonas species has been limited by poor transformation efficiencies. Here, we establish a highly efficient electroporation protocol for Halomonas elongata DSM 2581. This method also proved transferable to other Halomonas strains, encouraging further genetic manipulation work in underexplored species.
