Biofilm Interaction Mapping and Analysis (BIMA) of Interspecific Interactions in Pseudomonas Co-culture Biofilms. Front Microbiol 2021; 12:757856.

Abstract
Pseudomonas species are ubiquitous in nature and include numerous medically, agriculturally and technologically beneficial strains of which the interspecific interactions are of great interest for biotechnologies. Specifically, co-cultures containing Pseudomonas stutzeri have been used for bioremediation, biocontrol, aquaculture management and wastewater denitrification. Furthermore, the use of P. stutzeri biofilms, in combination with consortia-based approaches, may offer advantages for these processes. Understanding the interspecific interaction within biofilm co-cultures or consortia provides a means for improvement of current technologies. However, the investigation of biofilm-based consortia has been limited. We present an adaptable and scalable method for the analysis of macroscopic interactions (colony morphology, inhibition, and invasion) between colony-forming bacterial strains using an automated printing method followed by analysis of the genes and metabolites involved in the interactions. Using Biofilm Interaction Mapping and Analysis (BIMA), these interactions were investigated between P. stutzeri strain RCH2, a denitrifier isolated from chromium (VI) contaminated soil, and 13 other species of pseudomonas isolated from non-contaminated soil. One interaction partner, Pseudomonas fluorescens N1B4 was selected for mutant fitness profiling of a DNA-barcoded mutant library; with this approach four genes of importance were identified and the effects on interactions were evaluated with deletion mutants and mass spectrometry based metabolomics.

Abstract
Microalgae are promising sustainable and renewable sources of oils that can be used for biodiesel production. In addition, they contain important compounds, such as proteins and pigments, which have large applications in the food and pharmaceutical industries. Combining the production of these valuable products with wastewater treatment renders the cultivation of microalgae very attractive and economically feasible. This review paper presents and discusses the current applications of microalgae cultivation for wastewater treatment, particularly for the removal of phenolic compounds. The effects of cultivation conditions on the rate of contaminants removal and biomass productivity, as well as the chemical composition of microalgae cells are also discussed.

Abstract
Biofilm systems can be modeled using a variety of analytical and numerical approaches, usually by making simplifying assumptions regarding biofilm heterogeneity and activity as well as effective diffusivity. Inhibition kinetics, albeit common in experimental systems, are rarely considered and analytical approaches are either lacking or consider effective diffusivity of the substrate and the biofilm density to remain constant. To address this obvious knowledge gap an analytical procedure to estimate the effectiveness factor (dimensionless substrate mass flux at the biofilm-fluid interface) was developed for a continuum heterogeneous biofilm with multiple limiting-substrate Monod kinetics to different types of inhibition kinetics. The simple perturbation technique, previously validated to quantify biofilm activity, was applied to systems where either the substrate or the inhibitor is the limiting component, and cases where the inhibitor is a reaction product or the substrate also acts as the inhibitor. Explicit analytical equations are presented for the effectiveness factor estimation and, therefore, the calculation of biomass growth rate or limiting substrate/inhibitor consumption rate, for a given biofilm thickness. The robustness of the new biofilm model was tested using kinetic parameters experimentally determined for the growth of Pseudomonas putida CCRC 14365 on phenol. Several additional cases have been analyzed, including examples where the effectiveness factor can reach values greater than unity, characteristic of systems with inhibition kinetics. Criteria to establish when the effectiveness factor can reach values greater than unity in each of the cases studied are also presented.

Abstract
Pseudomonas stutzeri strain 9 was isolated from petroleum-contaminated soil. The main purpose of this study was to investigate how the long-term contact of this strain with diesel oil influences its surface and biodegradation properties. The experiments showed that the tested strain was able to degrade aromatic alkyl derivatives (butylbenzene, sec-butylbenzene, tert-butylbenzene and isobutylbenzene) and that the storage conditions had an influence on the cell surface properties. Also greater agglomeration of the cells was observed in the scanning electron microscope (SEM) micrographs and confirmed in particle size distribution results. The results also indicated that the addition of rhamnolipids to the hydrocarbons led to modification of the surface properties of P. stutzeri strain 9, which could be observed in the zeta potential and hydrophobicity values.

Abstract
Eighteen 4-t-octylphenol-degrading bacteria were isolated and screened for the presence of degradative genes by polymerase chain reaction method using four designed primer sets. The primer sets were designed to amplify specific fragments from multicomponent phenol hydroxylase, single component monooxygenase, catechol 1,2-dioxygenase and catechol 2,3-dioxygenase genes. Seventeen of the 18 isolates exhibited the presence of a 232 bp amplicon that shared 61-92% identity to known multicomponent phenol hydroxylase gene sequences from short and/or medium-chain alkylphenol-degrading strains. Twelve of the 18 isolates were positive for a 324 bp region that exhibited 78-95% identity to the closest published catechol 1,2-dioxygenase gene sequences. The two strains, Pseudomonas putida TX2 and Pseudomonas sp. TX1, contained catechol 1,2-dioxygenase genes also have catechol 2,3-dioxygenase genes. Our result revealed that most of the isolated bacteria are able to degrade long-chain alkylphenols via multicomponent phenol hydroxylase and the ortho-cleavage pathway.

Abstract
The biodegradation of bromoamine acid (BAA) in a combined airlift loop reactor (ALR) and biological activated carbon (BAC) system was investigated. The results showed that the ALR using Sphingomonas xenophaga as inoculum and granular activated carbon (GAC) as carrier, could run steadily for over 3 months at less than 950 mg L(-1) BAA. And the efficiencies of BAA decolorization and COD removal in ALR reached about 90% and 50% within 12h, respectively. When it was further aerated for another 12h, the ALR effluent gradually became yellow due to the auto-oxidation of BAA decolorization products which were identified by HPLC-MS. Further biotreatment of the ALR effluent using BAC showed that the efficiency of TOC removal could reach 90%. Moreover, the release efficiencies of Br(-) and SO(4)(2-) were 73.5% and 67.4%, respectively. It indicated that BAC system was effective in the biodegradation of the auto-oxidative BAA decolorization products.

Abstract
Phenol degradation was carried out by using a modified three-stage airlift packing-bed bioreactor. A laboratory-scale airlift packing-bed reactor, with hydrodynamic flexible packing material in the three-stage bioreactor, was constructed and operated for phenol removal from synthetic wastewater. The airlift packing-bed reactor successfully degraded phenol and lowered the chemical oxygen demand (COD) of wastewater. High COD removal was observed, and much lower sludge effluent was obtained in this investigation. This airlift bioreactor showed a superior hydrodynamics performance and broad operating conditions for phenolic material removal. Different operating modes were discussed to obtain the optimal condition for phenol degradation (i.e., hydraulic retention time [HRT] and gas flowrate of airlift). The HRT and feed phenol concentration of wastewater dominated the removal efficiency of phenol and COD. In this bioreactor, surface loading up to 2.84 g phenol/ m2 x d, almost 100% phenol removal, and over 90% COD removal was achieved. The lower operating cost combined with higher phenol-removal efficiency and a low sludge effluent concentration can be achieved by using this reactor for phenol wastewater treatment.

Abstract
The scope of this study is to evaluate the performance of internal loop airlift bioreactor (ILALR) in treating synthetic wastewater containing phenol and m-cresol, in single and multi component systems. The microbe utilized in the process was an indigenous mixed strain of Pseudomonas sp. isolated from a wastewater treatment plant. The reactor was operated at both lower and higher hydraulic retention times (HRTs) i.e., 4.1 and 8.3 h, respectively, by providing an inlet feed flow rate of 5 and 10 mL/min. Shock loading experiments were also performed up to a maximum concentration of 800 mg/L for phenol at 8.3 h HRT and 500 mg/L for m-cresol at 4.1 h HRT. The study showed complete degradation of both phenol and m-cresol, when they were degraded individually at a HRT of 8.3 h. Experiments with both phenol and m-cresol present as mixtures were performed based on the 2(2) full factorial design of experiments.

Abstract
An internal loop airlift reactor (ILALR) is developed and studied for biodegradation of phenol/m-cresol as single and dual substrate systems under batch and fed batch operation using an indigenous mixed microbial strain, predominantly Pseudomonas sp. The results showed that the culture could degrade phenol/m-cresol completely at a maximum concentration of 600mgl(-1) and 400mgl(-1), respectively. Batch ILALR study has revealed that phenol has been preferentially degraded by the microbial culture rather than m-cresol probably owing to the toxic effect of the later. Sum kinetic model evaluated the interaction between the phenol/m-cresol in dual substrate system, which resulted in a high coefficient of determination (R(2)) value >0.98). The fed batch results showed that the strain was able to degrade phenol/m-cresol with maximum individual concentrations 600mgl(-1) each in 26h and 37h, respectively. Moreover for fed batch operation, degradation rates increased with increase in feed concentration without any lag in the degradation profile.

Abstract
Granular activated carbon (GAC) was incorporated into hollow fiber membrane bioreactors for the biodegradation of 1,000 mg phenol l(-1) through immobilization of Pseudomonas putida. The phenol was removed within 25 h in the hybrid bioreactor, comparing with 31 h for a GAC-free bioreactor. Sorption, biodegradation, desorption, and bioregeneration were four steps for the phenol removal during batch operation.

Abstract
Despite the economic and sanitary problems caused by harmful biofilms, biofilms are nonetheless used empirically in industrial environmental and bioremediation processes and may be of potential use in medical settings for interfering with pathogen development. Escherichia coli is one of the bacteria with which biofilm formation has been studied in great detail, and it is especially appreciated for biotechnology applications because of its genetic amenability. Here we describe the development of two new genetic tools enabling the constitutive and inducible expression of any gene or operon of interest at its native locus. In addition to providing valuable tools for complementation and overexpression experiments, these two compact genetic cassettes were used to modulate the biofilm formation capacities of E. coli by taking control of two biofilm-promoting factors, autotransported antigen 43 adhesin and the bscABZC cellulose operon. The modulation of the biofilm formation capacities of E. coli or those of other bacteria capable of being genetically manipulated may be of use both for reducing and for improving the impact of biofilms in a number of industrial and medical applications.
