This study aimed at exploring microalgal heterogeneity from fresh water samples collected from inland water bodies in the heavily built city of Singapore. Culturable pure isolates (n = 94) were subject to an in-house microalgal DNA extraction method and LSU rDNA sequencing. Isolates were analysed for their predominance and distribution. A total of 17 different algal genera were identified (H = 2.8, E = 0.6), of which Scenedesmus spp. and Chlorella spp. constituted 27.5% and 21.3% of isolates respectively, followed by Micractinium spp. (18.8%) and Chlamydomonas spp. (12.5%). We also report 16 new microalgal strains from this region. The data is important from an ecological and biotechnological perspective.

Marine ecosystems are in the spotlight, because environmental changes are threatening biodiversity and ecological functions. In this context, microalgae play key ecological roles both in planktonic and benthic ecosystems. Consequently, they are considered indispensable targets for global monitoring programs.

This work tackles a supercritical fluid extraction (SFE) of microalga spirulina (Arthrospira platensis) to recover potential products from a nutritional and bioactive point of view. The execution of a response-surface model (RSO) through Box-Behnken design yielded 86% defatting, which significantly contrasts traditional Soxhlet extraction (9%). Contrarily to most of the reported works in the literature that focused on the analysis of the recovered oil, this study points out the added value of the remaining cakes after processing (spirulina residues).

The search for safe and effective anti-inflammatory agents remains a critical area of research due to the widespread impact of chronic inflammatory diseases. Natural compounds, particularly those derived from marine sources, present a promising avenue for developing novel therapeutics. In this study, we investigated the potential of Chlorella vulgaris, a unicellular green alga with a rich profile of bioactive compounds, as a source of anti-inflammatory agents.

The microalgae Euglena holds promise for biofuel production due to its high lipid content. However, the lipid productivity of current species/strains for biofuel production remains suboptimal due to limitations in strain selection. Therefore, this study aims to isolate and identify novel Euglena species or strains with high biomass and lipid productivity to enhance biofuel production from a desirable environment.

Accurate identification of microalgae is vital for marine ecological monitoring, algal bloom early warning, and environmental management. However, existing methods often struggle with misclassification due to the morphological similarity and biological complexity of microalgae. To address this, we propose HySwinFormer, a dual-branch deep learning architecture designed for fine-grained classification of microalgal images.
