Antimicrobial and Cytotoxic Activities of Biogenic Nanoparticles Produced by Cyanobacteria

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The article reviews the green synthesis of biogenic nanoparticles produced by cyanobacteria, highlighting their antimicrobial and cytotoxic properties. These nanoparticles, formed intra‐ or extracellularly, show activity against Gram‐positive and Gram‐negative bacteria as well as fungi and can induce apoptosis in tumor cells.

Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites

Advanced Materials, Volume 38, Issue 13, 3 March 2026.
Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.

Effects of CO₂ and pH on Stichococcus bacillaris in Laboratory Scale Photobioreactors

Chemical Engineering Transactions, 2012
The effects of both the CO2 concentration and the pH of the medium on biodiesel production by Stichococcus bacillaris (ACUF 158/11) were reported. Indoor cultures of S. bacillaris were carried out in both 0.6 L vertical bubble column photobioreactors and

Preventing biofouling in microalgal photobioreactors

Bioresource Technology
Photobioreactors (PBRs) are used to grow the light-requiring microalgae in diverse commercial processes. Often, they are operated as continuous culture over months period. However, with time, biofouling layer develops on the inner surfaces of their walls.

Analysis of Microalgae Growth in Residual Light: a Diagnostics Tool for Low-Cost Alternative Cultural Media

Chemical Engineering Transactions, 2014
Chapter 1 Most microalgae grow in photoautotrophy and some benefit from mixotrophy and their growth essentially depends on the effective available light intensity.
