Comparative Analysis of Effect of Culture Conditions on Growth and C-Phycocyanin Production in Helical and Linear Spirulina
Curr Microbiol. 2024 Apr 23;81(6):152. doi: 10.1007/s00284-024-03684-y.ABSTRACTSpirulina (Arthrospira and Spirulina spp.) has always been characterized by the helical trichomes, despite the existence of linear forms. A great debate is now open on the morphological flexibility of Spirulina, but it seems that both trichome morphology and C-phycocyanin (C-PC) concentrations are influenced by the culture conditions.This work compared the effect of some key growth factors (medium pH as well as its carbon, potassium, and salt contents) on the growth and C-PC concentration of helical and linear Spirulina strains. Further, two-pha...

As the lakes that flamingos inhabit expand, the birds ’ food supplies are rapidly shrinking
Every year, millions of lesser flamingos (
Phoeniconaias minor
) flock to a few small soda lakes in East Africa, attracting as many tourists as do migrating wildebeest. But the bright pink birds’ numbers are falling sharply, a decline researchers have now linked to a paradoxical effect of climate change.
Rainfall in the region is increasing, expanding the lakes, which might suggest the flamingos’ habitat is growing. But the extra water dilutes the nutrients in the lakes, depleting the microbes on which the birds feed, researchers report today in
Current Biology
. So, even as the lakes expand...

Molecules, Vol. 29, Pages 1747: The Impact of Different Drying Methods on the Metabolomic and Lipidomic Profiles of Arthrospira platensis
rewicz
Drying is an inseparable part of industrial microalgae production. In this work, the impacts of eight different drying methods on the metabolome and lipidome of Arthrospira platensis were investigated. The studied drying methods were freeze drying (FD), sun drying (SD), air drying at 40 and 75 °C (AD′ and AD″), infrared drying at 40 and 75 °C (IRD′ and IRD″), and vacuum drying at 40 and 75 °C (VD′ and VD″). Results gathered by reversed-phase liquid chromatography separation coupled with high-re...

Investigation on the enhancement of crack restoration properties in cement incorporated with Arthrospira platensis cultured in modified medium
This study investigated the potential use of microalgae as partial cement replacement to heal cracks in cement mortar. Microbially induced calcite (CaCO3) precipitation (MICP) from Arthrospira platensis (A. platensis) (UMACC162) was utilised for crack-healing applications. Microalgae was cultivated in Kosaric Media (KM) together with filtered cement water (FCW), and used as a cement replacement material. The microalgal species was further evaluated for its capacity and adaptability towards large-scale culturing. The results showed that A. platensis could adapt and survive in cement water solution and cement mortar, suggest...

Cradle-to-gate life cycle assessment of Spirulina bioplastic produced via plasticization with glycerol
In this study, cradle-to-gate life cycle assessment (LCA) was carried out in openLCA program using the Agribalyse database, to evaluate the environmental impacts of Spirulina bioplastic, formed from plasticization of Spirulina powder with glycerol. Two processes were created for the inventories of (i) Spirulina powder and (ii) Spirulina bioplastic, where the output of the former served as an input for the latter. The extruded bioplastic sheets were food-grade and could be used as edible packaging materials. The bioplastic was also compared to conventional plastics and it was found that the energy consumption was 3.83 ± 0....
