Abstract

This paper describes part of a project to develop a systematic approach to knowledge extraction from on-line respirometric measurements in support of wastewater treatment plant control and operation. The paper deals with the following issues: (1) test of the implementation of an automatic set-up consisting of a continuous laboratory respirometer integrated in a mobile trailer with sampling and dosing equipment, and data-acquisition and communication system; (2) assessment of activated sludge/sewage characteristics from sludge respirograms by model parameter estimation; (3) comparison of the parameter estimates with regular plant data and information obtained from supplementary wastewater respirograms. The paper describes the equipment and some of its measuring results from a period of one week at a large-scale wastewater treatment plant. The measurements were evaluated in terms of the common activated sludge modelling practice. The automatic set-up allowed reliable measurements during at least one week. The data were used to calibrate two different version of the model, and independent parameter estimates were obtained.

Unraveling the ecological success of Iodidimonas in a bioreactor treating oil and gas produced water.

UNLABELLED: Iodidimonas sp., a bacterium found in bioreactors treating oil and gas produced water as well as iodide-rich brines, has garnered attention for its unique ability to oxidize iodine. However, little is known about the metabolic capabilities that enable Iodidimonas sp. to thrive in certain unique ecological niches. In this study, we isolated, characterized, and sequenced three strains belonging to the Iodidimonas genus from the sludge of a membrane bioreactor used for produced water treatment. We investigated the genomic features of these isolates and compared them with the four publicly available isolate genomes from this genus, as well as a metagenome-assembled genome from the source bioreactor. Our Iodidimonas isolates had several genes associated with mitigating salinity, heavy metal, and organic compound stress, which likely help these bacteria to survive in produced water. Phenotyping tests revealed that while the isolates could utilize a wide variety of simple carbon substrates, they failed to degrade aliphatic or aromatic hydrocarbons, consistent with the lack of genes associated with common hydrocarbon degradation pathways in their genomes. We hypothesize that these microbes may lead a scavenging lifestyle in the bioreactor and similar iodide-rich brines. IMPORTANCE: Occupying a niche habitat and having few representative isolates, the genus Iodidimonas is a relatively understudied alphaproteobacterial group. Its ability to corrode pipes in iodine production facilities has economic implications, and its ability to generate potentially carcinogenic iodinated organic compounds during treatment of oil and gas produced water may cause environmental and health concerns with the recycling of treated water. Therefore, detailed characterization of the metabolic potential of the Iodidimonas isolates in this study both sheds light on their adaptation to the environmental conditions they inhabit and has environmental and economic significance.

Protein production and induction of the unfolded protein response in Trichoderma reesei strain Rut-C30 and its transformant expressing endoglucanase I with a hydrophobic tag.

The effect of induction of protein production was studied in bioreactor cultures of T. reesei strain Rut-C30 and its transformant expressing endoglucanase I core domain (EGI, Cel7B) fused with a hydrophobic peptide tag. The tag was previously designed for efficient purification of the fusion protein in aqueous two-phase separation. The fungi were first grown on glucose-containing minimal medium after which rich medium with lactose as a carbon source was added to induce cellulase production. Production of extracellular protein and cellulase activity and the transcript levels of the major cellulase genes were analyzed during the cultivations. Induction of the cellulase genes followed a similar temporal pattern in both strains. The first phase of induction took place after addition of lactose as soon as glucose was depleted, and the second phase after lactose was consumed. Western analysis showed that a decreased amount of fusion protein was produced in the culture medium compared with the endogenous EGI, although the strain harbors several copies of the recombinant gene under the strong cbh1 promoter. The fusion protein appeared to accumulate within the cells, indicating impaired secretion of the protein. The mRNA levels of the UPR (unfolded protein response) target genes, bip1 and pdi1, and the level of the active form of hac1 transcript encoding the UPR transcription factor increased concurrently with induction of the cellulase genes in both strains, indicating increased requirement of the folding machinery under these conditions. However, only a minor increase in bip1 and pdi1 transcript level was observed in the transformant compared with the parental strain.

Production of Dunaliella salina biomass rich in 9-cis-beta-carotene and lutein in a closed tubular photobioreactor.

Performance of Dunaliella salina cultures outdoors in a closed tubular photobioreactor has been assessed. Optimization of conditions involved verification of the effect of several determining factors on the yield of both biomass and carotenoids. Maximal biomass productivity (over 2g (dry weight) m(-2) d(-1) or 80 gm(-3) d(-1)) was achieved at 38 cm s(-1), flow rate; 2 x 10(9) cells l(-1), initial population density; 25 degrees C, temperature; semi-continuous regime, keeping a cell density interval between 2 x 10(9) and over 4 x 10(9) cells l(-1). Coverage of the tubular loop with a sunshade screen to avoid light-induced damage of cells was essential to maintain growth performance. The cellular beta-carotene level increased significantly during the light period, as also did that of lutein. The rise in the beta-carotene level could be accounted by the 9-cis-isomer, with all-trans-beta-carotene remaining steady during the light period. By sunset, the ratio between 9-cis- and all-trans-isomers of beta-carotene amounted to 1.5, with over 60% of total beta-carotene corresponding to the 9-cis-isomer. Removal of sunshade enhanced carotenoid accumulation by cells to reach up to 10% of dry biomass. Cultivation of Dunaliella in closed tubular photobioreactor, thus represents a suitable approach for the production of a high-quality microalgal biomass enriched in the valuable 9-cis-isomer of beta-carotene and lutein.
