Summary: Multi-omic and evolutionary analyses of the ultrasmall green alga, Medakomo hakoo, suggest it belongs to a new genus within the class Trebouxiophyceae and provide insight into essential genes for microalgae. With a genome size of 15.8 Mbp and 7629 genes, it is among the smallest genomes in the Viridiplantae. Comparative analyses reveal shared gene sets among 15 ultrasmall algae, enabling identification of essential genes for metabolism and cellular functions.

Summary: An efficient genetic manipulation system was developed in the industrial strain C. empetri MEFC009, allowing for genetic modification and verification of essential genetic elements. High homologous recombination frequency was achieved by deleting the ku80 gene, facilitating gene-targeting. This system proved useful in identifying the polyketide synthase responsible for DHN-melanin biosynthesis.

Summary: The green alga Parachlorella sp. BX1.5 has been found to produce a novel acidic rhamnan of high molecular mass, which shows thickening and resistance to environmental stress conditions when added to mayonnaise. This suggests its potential application as a thickener or food additive with improved oil-off properties.

Summary: Growing microalgae on rotten potato media is a cost-effective way to enhance biomass production. The study found that using 25% digested rotten potato supernatant as a growth medium resulted in the highest cell density, chlorophyll-a content, and optical density of Monoraphidium littorale. It also showed significantly higher protein and lipid contents compared to other treatments.

Summary: The use of oil refineries to convert second generation biomass into fuels is an effective way to reduce carbon footprint. By converting biomass under mild conditions using acetone, a new bio-petroleum composed of sugar acetals can be obtained without carbon loss. The study reveals the transformation pathway of DX and its interaction with hydrocarbons, providing insights for improving the catalysts and process of bio-petroleum conversion.

Summary: Chlorinated aliphatic hydrocarbons (CAHs) are potentially toxic substances that have been commonly found in contaminated environments. This study investigates the composition, function, and assembly of soil bacteria in an aged CAH-contaminated site using high-throughput sequencing analysis. The presence of organohalide-respiring bacteria (OHRB) is crucial in reducing the environmental stress of CAHs and improving the diversity and stability of the bacterial community. The findings suggest that the metabolic community in deep soil can potentially contribute to the monitored natural attenuation technology for CAH-contaminated sites.

Summary: This study investigates the efficiency of four strains of Pseudomonas aeruginosa and their biosurfactants in the bioremediation process. The results show that these strains and their consortia are capable of degrading crude oil, and the addition of biosurfactants can further enhance the degradation performance.

Summary: Genetic transformation in legume plants is an important area of agricultural research. Despite some progress in improving crop yields, challenges such as recalcitrance and genotype-dependence still exist. Future research may focus on overcoming these obstacles and further increasing yields.

Summary: This study introduces a new observational method for mapping the distribution of aliphatic hydrocarbon content in the solid phase in our Galaxy. The results show a weak trend of increasing optical depth towards the Galactic Centre at b = 0 degrees and suggest that at least 10-20% of carbon in the Galactic plane exists in aliphatic form.

Summary: Antarctica is home to a variety of cold-resistant algae, with one green algae species, Chlamydomonas sp. UWO241, possessing numerous ice-binding proteins and duplicated genes that aid in its survival in the extreme environment. The ongoing phenomenon of gene and partial gene duplication in UWO241 may be mediated by retrotransposons, potentially playing a role in adaptation to extreme environments.

Summary: This report presents a microalga, Scenedesmus glucoliberatum PABB004, with potential applications in fermentative processes and co-culture schemes due to its high sugar secretion phenotype. The genome of this strain has a high GC content of 78%. It secretes fermentable sugars at high levels over a broad pH range, expanding our understanding of algal mutualistic relationships involving sugar exchanges.

Summary: The study comprehensively describes the subtelomere architecture of the 17 chromosomes of Chlamydomonas reinhardtii and identifies three main repeated elements in subtelomeres. Analysis shows that Sultan elements underwent segmental duplications within subtelomeres and rearranged between them at a lower frequency. Other green algae also exhibit species-specific repeated elements shared across subtelomeres.
