Algae are diverse organisms with significant biotechnological potential for resource circularity. Taking inspiration from fermentative microbes, engineering algal genomes holds promise to broadly expand their application ranges. Advances in genome sequencing with improvements in DNA synthesis and delivery techniques are enabling customized molecular tool development to confer advanced traits to algae. Efforts to redesign and rebuild entire genomes to create fit-for-purpose organisms currently being explored in heterotrophic prokaryotes and eukaryotic microbes could also be applied to photosynthetic algae. Future algal genome engineering will enhance yields of native products and permit the expression of complex biochemical pathways to produce novel metabolites from sustainable inputs. We present a historical perspective on advances in engineering algae, discuss the requisite genetic traits to enable algal genome optimization, take inspiration from whole-genome engineering efforts in other microbes for algal systems, and present candidate algal species in the context of these engineering goals.

Mapping the metagenomic diversity of the multi-kingdom glacier-fed stream microbiome.

Article Synopsis
- Glacier-fed streams (GFS) are extreme aquatic ecosystems with little nutrients and fluctuating environments, where microorganisms predominantly form biofilms.
- Researchers analyzed 156 metagenomes from various mountain ranges, revealing thousands of metagenome-assembled genomes (MAGs) of prokaryotes, algae, fungi, and viruses that demonstrate complex biotic interactions in these biofilms.
- The study found that as glaciers shrink, biofilms transition from using inorganic energy sources to relying more on heterotrophy as algal biomass increases, highlighting the adaptability of microbial life in these unique ecosystems amid climate change.

Coccolithophores comprise a major component of the oceanic carbon cycle. These unicellular algae produce ornate structures made of calcium carbonate, termed coccoliths, representing ~ 50% of calcite production in the open ocean. The exact molecular mechanisms which direct and control coccolith formation are unknown.

A novel air-to-liquid mass transfer system using wetted rotating membranes was designed to enhance air-to-liquid carbon dioxide (CO) mass transfer efficiency. Traditional methods, such as sparging, are energy-intensive, but the rotating membrane reduces energy demands by optimising membrane wetting via rotational motion. Experimental tests were conducted using a small-scale system with a membrane width of 0.

Although the symbiotic partnership between corals and algal endosymbionts has been extensively explored, interactions between corals, their algal endosymbionts and microbial associates are still less understood. Screening the response of natural microbial consortiums inside corals can aid in exploiting them as markers for dysbiosis interactions inside the coral holobiont. The coral microbiome includes archaea, bacteria, fungi, and viruses hypothesized to play a pivotal vital role in coral health and tolerance to heat stress condition via different physiological, biochemical, and molecular mechanisms.
