“…It was obvious from the results that the molarity of GB and salt ions diffusing into the EPS were inversely proportional. This suggested that the more GB accumulated in EPS, the fewer salt ions diffused into it, further relieving the osmotic pressure [ 34 ].…”

“…For the deeper layers, the biomarkers revealed by LEfSe analysis correspond to OTUs affiliated with halophilic bacteria found in hypersaline ecosystems. They include Coxiella, Anaerophaga, and Balneolaceae for layer L2, exhibiting anaerobic metabolism (Song et al, 2021;Wu et al, 2022). This finding is in agreement with the reversed redox gradient observed in the Salineta wetland.…”

Microbial communities inhabiting hypersaline wetlands, well adapted to the environmental fluctuations due to flooding and desiccation events, play a key role in the biogeochemical cycles, ensuring ecosystem service. To better understand the ecosystem functioning, we studied soil microbial communities of Salineta wetland (NE Spain) in dry and wet seasons in three different landscape stations representing situations characteristic of ephemeral saline lakes: S1 soil usually submerged, S2 soil intermittently flooded, and S3 soil with halophytes. Microbial community composition was determined according to different redox layers by 16S rRNA gene barcoding. We observed reversed redox gradient, negative at the surface and positive in depth, which was identified by PERMANOVA as the main factor explaining microbial distribution. The Pseudomonadota, Gemmatimonadota, Bacteroidota, Desulfobacterota, and Halobacteriota phyla were dominant in all stations. Linear discriminant analysis effect size (LEfSe) revealed that the upper soil surface layer was characterized by the predominance of operational taxonomic units (OTUs) affiliated to strictly or facultative anaerobic halophilic bacteria and archaea while the subsurface soil layer was dominated by an OTU affiliated to Roseibaca, an aerobic alkali-tolerant bacterium. In addition, the potential functional capabilities, inferred by PICRUSt2 analysis, involved in carbon, nitrogen, and sulfur cycles were similar in all samples, irrespective of the redox stratification, suggesting functional redundancy. Our findings show microbial community changes according to water flooding conditions, which represent useful information for biomonitoring and management of these wetlands whose extreme aridity and salinity conditions are exposed to irreversible changes due to human activities.

Palm Oil Mill Effluent (POME) is waste generated by the palm oil industry consisting of solid, liquid and gaseous wastes. POME is decomposed in sewage ponds and allowed to decompose naturally. The residual waste generated by this industry is non-toxic but has high polluting power. To overcome this, it is necessary to treat waste by making ceramic membranes. The composition materials needed are clay, zeolite, sodium carbonate and boric acid. The manufacturing method is through the printing and combustion stages at a temperature of 900oC. The results showed that there was an effect of compositional variations on the quality of the final product, namely TSS rejection % 93.355 with a flux value of 0.2474 (L/m2min). From the parameter values obtained, it proves that the ceramic membrane is able to process POME with satisfactory effective results. The quality standard of palm oil liquid waste is in accordance with South Sumatera governor regulation number 8 of 2012 concerning quality standard of liquid waste for industrial, hotel, hospital, domestic and coal mining activities
