“…However, for high altitude lakes in Qinghai-Tibet, TP showed a positive correlation for benthic algal communities (Yang et al, 2018). As most macronutrients were insignificant in the present study, they may not be a strong limiting factor for benthic algae in the sub-Arctic unlike in lower latitudes (Sun et al, 2022). Overall, the low chlorophyll a values and oligotrophic pond conditions result from to low anthropogenic impact and productivity, as well as nutrient-poor soils (Wetzel, 2001) while for an example boreal and tropical freshwater streams typically have notably higher algal biomasses (Guo et al, 2020;Rosero-López et al, 2021).…”

This study investigated the spatial variation in total benthic algal biomass and within cyanobacteria, green algae, and diatoms in sub-Arctic ponds. Additionally to more widely used explanatory variables, snowmelt and ice duration were considered as their importance on algal communities is poorly understood. The data comprised algal biomasses from 45 sub-Arctic ponds in the Finnish Lapland. A generalized linear model and hierarchical partitioning were used to identify the significantly influential variables. Cyanobacteria were the most abundant algal group. Trace elements (e.g. Fe, Al, and Mn) were the most significant explanatory variable group in explaining algal biomasses. Macronutrients apart from K were found insignificant in all models. There were positive relationships between some algal biomasses indicating no strong competition between them. Snow and ice variables were found insignificant for all models, but they could have an important secondary role on algal communities. The results highlight the importance of trace elements in shaping algal biomasses in sub-Arctic ponds and thus their wider use in research can be advocated to better understand the productivity of nutrient poor and acidic waters in sub-Arctic regions. Focussing on benthic algal biomasses and the chemical composition of sub-Arctic freshwaters provides important information on the aquatic primary production.

“…Another factor contributed to the growth of microalgae yield is light:dark cycle (Gautam and Vinu 2020; Sun et al 2022). Accumulation of cell material and cell increasing rely on light as a source of energy (Fu et al 2012;Gong et al 2014).…”

Chlorella sp. is able to grow and transform inorganic and organic contaminants in wastewater to create biomass. In the present study, Chlorella sp. LH2 isolated from cocoon wastewater was able to thrive in hospital wastewater, then remove nutrients and eliminate E. coli ATCC 8739. The results indicated that optimal cultivation conditions of Chlorella sp. LH2 in hospital wastewater were pH of 8, light:dark cycle of 16:8 at 30oC. The inhibitory effect of chlorination on algae growth was accompanied with the chlorine concentration. BOD5:COD ratio of 0.77 indicated biodegradability of hospital wastewater. The removal efficiency of COD, BOD5, total nitrogen and total phosphorous were 80.53%, 87.55%, 68.64% and 64.44% after 9 days, respectively. Elimination of E. coli ATCC 8739 after 7 days by Chlorella sp. LH2 was 88.92%. The results of this study suggest the nutrients and pathogens removal potential of Chlorella sp. LH2 in hospital wastewater for further practical applications.
