Drylands occupy approximately 41% of the Earth's terrestrial surface. Climate change and land use practices are expected to affect biogeochemical cycling by soil microbiome in these ecosystems. Understanding how microbial community might respond drivers is extremely important mitigate processes degradation desertification. The Caatinga, an exclusively Brazilian biome composed extensive seasonal tropical dry forest, exposed variable spatiotemporal rainfall patterns as well strong human-driven...
Two expanded granular sludge bed reactors were operated. RAB (adapted biomass) was operated in two stages: Stage I, with standard LAS (13.2 mg L−1); and II, which the replaced by diluted laundry wastewater according to concentration (11.2 L−1). RNAB (not adapted had a single stage, using direct (11.5 Thus, strategy of biomass adaptation did not lead an increase surfactant removal (RAB-Stage II: 77%; RNAB-Stage I: 78%). By means denaturing gradient gel electrophoresis, 80% similarity verified...
Abstract The 16S r RNA gene amplicon and whole‐genome shotgun metagenomic ( WGSM ) sequencing approaches were used to investigate wide‐spectrum profiles of microbial composition metabolic diversity from a full‐scale UASB reactor applied poultry slaughterhouse wastewater treatment. data generated by using MiSeq 2 × 250 bp HiSeq 150 Illumina platforms for sequencing, respectively. Each approach revealed distinct community profile, with Pseudomonas Psychrobacter as predominant genus the dataset...
This study evaluated linear alkylbenzene sulfonate removal in an expanded granular sludge bed reactor with hydraulic retention times of 26 h and 32 h. Sludge separator phase biomass were phylogenetically characterized (sequencing 16S rRNA) quantified (most probable number) to determine the total anaerobic bacteria methanogenic Archaea. The was fed a mineral medium supplemented 14 mg l−1 LAS, ethanol methanol. stage I-32 consisted adaptation (without LAS influent) until stability achieved...
The objective of this study was to evaluate the removal linear alkylbenzene sulfonate (LAS) from commercial laundry wastewater using an expanded granular sludge bed (EGSB) reactor with two specific LAS loading rates (SLLRs), 1.0 and 2.7 mg gVS−1 d−1. biomass characterized denaturing gradient gel electrophoresis (DGGE) 16S Ion Tag sequencing. Higher (92.9%) observed in association SLLR d−1 than (58.6%). A relationship between S−2 concentration effluent surfactant efficiency observed. This...
An expanded granular sludge bed reactor was evaluated for the anaerobic digestion of commercial laundry wastewater and domestic sewage focused on removal linear alkylbenzene sulfonate (LAS). The operated in three stages, all under mesophilic conditions with a hydraulic retention time 36 h. At stage I, diluted tap water (influent: 15.3 ± 4.9 mg LAS/L); at II, 50% feed volume mixture 15.8 III, only used as diluent 24.1 4.1 LAS/L). Due to addition organic compounds content LAS influent...
Degradation of linear alkylbenzene sulfonate (LAS) in UASB reactors was optimized by varying the bioavailability LAS based on concentration biomass system (1.3-16 g TS/L), hydraulic retention time (HRT), which operated at 6, 35 or 80 h, and co-substrates as specific organic loading rates (SOLR) ranging from 0.03-0.18 COD/g TVS.d. The highest degradation rate (76%) related to lowest SOLR (0.03 TVS.d). Variation HRT between 6 h resulted 18% 55%. discrete changes (ranging 37-53%). According...
Summary Antarctic terrestrial ecosystems are largely dominated by lichens, while shallow coastal environments mainly covered macroalgae. The aim of this study was to isolate and evaluate the diversity yeasts in different species macroalgae lichens collected South Shetland Islands, Antarctica. A total 405 were recovered (205 from 200 lichens). yeast community most than lichen. dominance index similar for both substrates. 24 taxa 18 identified, only 5 common Metschnikowia australis, Mrakia...
The biodegradation of linear alkylbenzene sulfonate (LAS) from commercial laundry wastewater was evaluated in an anaerobic fluidized bed reactor (FBR) fed with synthetic substrate (598 mg L(-1) to 723 organic matter) supplemented 9.5±3.1 27.9±9.6 LAS. average chemical oxygen demand (COD) removal efficiency 89% and the LAS 57% during 489 days FBR. Higher levels volatile fatty acids (VFA) were observed effluent at stage best performance. Increasing surfactant concentration did not increase VFA...
