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, EH = 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.

“…Algae generally have appeared in BBM cultures within three to four weeks (Lin et al., 2013). Pure cultures have been carried out in different growth media, including Bold's Basal Medium (BBM; Santhakumaran et al., 2019), BG‐11 medium (Grzesik et al., 2017), Gromova‐6 medium (Patova & Dorokhova, 2008), Z‐8 Medium (Flechtner et al., 2005), and NC medium (Lin & Wu, 2014), depending on suitability for specific algae or algal groups identified per the preliminary screening.…”

“…Many species of aquatic microalgae have been shown to be economically highly significant (Gupta et al., 2013; Jez et al., 2017; Kumar et al., 2020; Santhakumaran et al., 2019), and particular species of soil algae also could be significant biological resources for diverse human purposes. In general, microalgae have been shown to be rich in various metabolites (Kratzer & Murkovic, 2021; Minhas et al., 2016; Santhakumaran et al., 2020; Santhakumaran & Ray, 2021), including antibacterial metabolites (Abdel‐Raouf et al., 2018), antifungal compounds (Abdel‐Raouf et al., 2018; Righini et al., 2018), and plant stimulants (Righini et al., 2018).…”

Aero‐terrestrial algae are ecologically and economically valuable bioresources contributing to carbon sequestration, sustenance of soil health, and fertility. Compared to aquatic algae, the literature on subaerial algae is minimal, including studies of distinctive habitats such as forest soils, agricultural fields, deserts, polar regions, specific subaerial zones, artificial structures, and tropical soils. The primary goal here was to identify the gaps and scope of research on such algae. Accordingly, the literature was analyzed per sub‐themes, such as the “nature of current research data on terrestrial algae,” “methodological approaches,” “diversity,” “environmental relationships,” “ecological roles,” and “economic significance.” The review showed there is a high diversity of algae in soils, especially members belonging to the Cyanophyta (Cyanobacteria) and Chlorophyta. Algal distributions in terrestrial environments depend on the microhabitat conditions, and many species of soil algae are sensitive to specific soil conditions. The ecological significance of soil algae includes primary production, the release of biochemical stimulants and plant growth promoters into soils, nitrogen fixation, solubilization of minerals, and the enhancement and maintenance of soil fertility. Since aero‐terrestrial habitats are generally stressed environments, algae of such environments can be rich in rare metabolites and natural products. For example, epilithic soil algae use wet adhesive molecules to fix them firmly on the substratum. Exploring the ecological roles and economic utility of soil and other subaerial algae could be helpful for the development of algae‐based industries and for achieving sustainable soil management.

Detection of oleaginous microalgae with high lipid productivity is a crucial feature for biofuel and nutraceutical production. Therefore, screening of microalgae from different habitats has become highly significant to face the request on these bioresources. Accordingly, the present study aimed to screen the efficiency of biodiesel feedstocks and the ability to accumulate essential fatty acids of four green microalgae (Chlorolobion braunii, Tetradesmus obliquus, Monoraphidium miutum, and Asterarcys quadricellulare), isolated from soil samples of Benha Egypt. Although T.obliquus was the highest biomass productive species (689 mgL− 1d− 1), M. minutum recorded the top of lipid productivity (29 mg L− 1d− 1). Fatty acid profiles of the four microalgae confirmed their suitability for biodiesel production where it recorded biodiesel properties within the limits of international standards. Also, species selection through PROMETHEE and GAIA analysis revealed that C. braunii is the best promising as a potential source for biodiesel production because it has a high saturated fatty acids proportion (39.75%) and shows cetane number (54.99) and low iodine value (100.57) and many other biodiesel properties within the standards limit. In addition, the screened microalgae showed a high percentage of omega fractions in their total fatty acids. Asterarcys quadricellulare and M. minutum recorded high omega-3 fatty acids content of 34.4% and 28.9%, respectively.
