Optimization of the phototrophic Cyanobacteria polyhydroxybutyrate (PHB) production by kinetic model simulation

Science of The Total Environment, 2021
Cyanobacteria can grow using inorganic substrates, such as CO2 from industrial sources and nutrients from wastewaters, and therefore are promising microorganisms to produce polyhydroxybutyrate in a cleaner circular context. However, this biotechnological production is highly challenging because it involves different interlinked reactions that are ...

In Vivo Enzyme Catalytic Rates in Formate‐Growing Methanococcus maripaludis

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
In vivo catalytic rates of Methanococcus maripaludis enzymes during C1 carbon source limited growth were determined from metabolic model estimated fluxes and proteomics data. They showed weak agreement with turnover numbers predicted from sequences.

Analysis of mutational effects of a polyhydroxybutyrate (PHB) polymerase on bacterial PHB accumulation using an in vivo assay system [PDF]

FEMS Microbiology Letters, 2001
Polymerase is a central enzyme involved in the biosynthesis of polyhydroxybutyrate (PHB), a well-known bacterial biodegradable polyester. In this study, we have established an in vivo assay system to analyze mutational effects of Ralstonia eutropha polymerase (termed PhbC(Re)) on the level of PHB accumulation in recombinant strains of Escherichia coli.

Effects of Carbon‐to‐Nitrogen Ratio in Biofloc System on Water Quality, Growth Performance and Haematological Parameters of Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT A 10‐week indoor culture trial was carried out to assess the impact of various C/N ratios on the water quality, growth performance and haematology of Nile tilapia (Oreochromis niloticus) in a biofloc system. The experiment included four biofloc treatment groups with distinct C/N ratios (12:1, 15:1, 18:1 and 21:1) and a control group with a C/N

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
