Analysis of 16S rRNA gene-based community data in wastewaters revealed selective enrichment of Firmicutes and Actinobacteria, resulting in enhanced microalgal growth and nutrient removal. The findings of this novel study suggest that microalgal–bacterial co-cultures mediate interspecies interactions for a shift in population dynamics of the indigenous bacteria in wastewaters to facilitate enhanced bioremediation of effluents with sustainable production of biomass and biodiesel.]]> Tue 12 Sep 2023 13:42:26 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41934 Microcystis aeruginosa KW strain were observed in bloom samples and during the cultivation of cells in static broth cultures. RNA-seq based whole transcriptome sequencing was performed to examine the pattern of gene expression in these morphotypes. In total 493 differentially expressed transcripts were identified between the two morphotypes. Genes involved in photosynthesis, photosynthesis-related antenna proteins and oxidative phosphorylation were significantly upregulated in W-type cells relative to the control (S-type cells). Here we discussed the roles of these genes and showed that M. aeruginosa responds and acclimates to subtle variations in environmental parameters, especially light, through alteration of the transcript levels of relevant genes. Furthermore, additional physiological experiments such as analyses of photosynthetic activity, redox state and exopolysaccharide production provided further evidence and confirmed the validity of the transcriptomic results. The findings of this study provide greater insight into the metabolic pathways and complex mechanisms that may regulate the interaction and niche adaptation of this important bloom-forming organism in fluctuating environmental conditions.]]> Fri 17 Nov 2023 11:51:33 AEDT ]]>
