What is the influence of pH on bacteriophage abundance in wastewater? 


Best insight from top research papers

The influence of pH on bacteriophage abundance in wastewater varies depending on the specific bacteriophage and the pH conditions. For example, in the study by Marzban et al., bacteriophages isolated from wastewater treatment plants showed optimal growth and lytic activity against Listeria monocytogenes at pH 7 . In contrast, the study by Auroni et al. found that pH 4 caused a significant decline in the number of plaques for coliphages and shigaphages, while pH 11 had a negative effect on the survivability and growth of these bacteriophages . Langlet et al. demonstrated that pH close to the isoelectric point (pI) of viral particles led to significant aggregation processes and a decline in plaque forming unit (PFU) counts . Wu et al. investigated the pH-dependent pollutants removal in a biofilm-based wastewater treatment system and found that neutral conditions achieved the highest biofilm concentration and living cells, leading to the highest pollutants removal rates . Feng et al. observed that the survival rates of RNA F-specific coliphages MS2 and Qbeta were influenced by pH, with MS2 surviving better in acidic conditions and Qbeta having a better survival rate in alkaline conditions .

The provided paper does not mention anything about the influence of pH on bacteriophage abundance in wastewater.
The influence of pH on bacteriophage abundance in wastewater is negative. pH 4 caused a decline of 100% in the number of plaques for coliphages and a decline of 91.67% for shigaphages. pH 11 also caused a decline of 100% for coliphages and a decline of 91.67% for shigaphages.
The paper states that the optimal pH for the growth and release of bacteriophages from wastewater was pH 7.

Can pH affect bioremediation in wastewater?5 answerspH plays a significant role in bioremediation processes in wastewater treatment systems. Different pH levels can impact biofilm growth, microbial activity, pollutant removal efficiency, and biomass production rates. For instance, in a membrane biofilm reactor, neutral pH conditions were found to support the highest biofilm concentration and living cells, leading to optimal pollutants removal. Similarly, water hyacinth ponds showed optimal removal and biomass production at influent pH levels between 6.4 and 7.1. Additionally, pH influences the solar disinfection rates of bacteria in wastewater, with acidic conditions enhancing inactivation rates under sunlight. These findings highlight the importance of pH control in enhancing bioremediation efficiency and microbial activities in various wastewater treatment systems.
What is the influence of pH on Escherichia coli abundance in wastewater?4 answersThe influence of pH on Escherichia coli abundance in wastewater is significant. Different studies have shown that the initial pH of the wastewater affects the effectiveness of E. coli removal. Electrocoagulation processes using aluminum and ordinary steel electrodes have been found to remove E. coli effectively, with more than 5 log removal achieved under various pH conditions. Solar disinfection processes have also been studied, and it was found that pH influences the inactivation rates of E. coli in sensitizer-free matrices. Elevated solar inactivation rates were observed at pH 4 and pH 10 for both laboratory-cultured and wastewater-sourced E. coli. Additionally, electrocoagulation has been shown to have a high efficiency in removing E. coli from domestic and urban wastewaters, with the highest removal efficiency achieved at a neutral pH of 7. Overall, pH plays a crucial role in the abundance and removal of E. coli in wastewater treatment processes.
Can manipulating the pH of wastewater be used as a tool to control bacteriophage populations and improve water quality?5 answersManipulating the pH of wastewater can be used as a tool to control bacteriophage populations and improve water quality. Bacteriophages have been found to have lytic activity against pathogenic bacteria such as Listeria monocytogenes, which can be present in wastewater. By adjusting the pH to optimal conditions, bacteriophages can be proliferated and released, leading to a reduction in bacterial contamination. Additionally, phages have the potential to control bacterial communities and destabilize biofilms, which are critical sources of wastewater contamination. The use of phages as bioindicators and biocontrollers in wastewater treatment systems can help in the control of harmful bacteria and improve the efficiency of the treatment process. Furthermore, phage-based treatment has been shown to reduce water pollutants such as biological oxygen demand, chemical oxygen demand, turbidity, and ammonia, while increasing dissolved oxygen content, thus enhancing the physicochemical quality of water. Therefore, manipulating the pH of wastewater can be an effective and cost-efficient approach to control bacteriophage populations and improve water quality.
How do changes in orthophosphates levels affect the diversity and abundance of bacteriophages in wastewater ecosystems?5 answersChanges in orthophosphate levels can impact the diversity and abundance of bacteriophages in wastewater ecosystems. The addition of orthophosphate into aging and leaking drinking water systems can increase the concentration of phosphate leaching into urban streams, leading to shifts in microbial community composition and changes in key microbial phosphorus and nitrogen metabolism genes. The prevalence of phage families, such as Myoviridae, Siphoviridae, and Podoviridae, can be influenced by temporal variations and temperature conditions in wastewater treatment plants. Phages play a significant role in driving microbial diversity, and their interaction with bacterial hosts can affect the composition of microbial communities in different ecosystems. Understanding the ecological roles of phages in biological wastewater treatment systems is important for improving process monitoring and control, influent quality, and the potential use of phages as biocontrol agents. The influence of phage activity on the performance of wastewater treatment systems and the potential applications of phages in controlling sludge bulking/foaming and pathogens are also areas of research.
What is the influence of nickel concentration on bacteriophage abundance in wastewater?4 answersThe influence of nickel concentration on bacteriophage abundance in wastewater varies depending on the specific bacteriophage and the concentration of nickel. Some bacteriophages, such as Coliphage T1, are more sensitive to nickel than their host bacteria, with higher concentrations of nickel adversely affecting bacterial growth but not significantly impacting the bacteriophage. Other studies have shown that the removal of bacteriophage MS2 can be effectively achieved using Ni/Al layered double hydroxide (LDH), with the removal capacity of 5.5 × 107 pfu g−1. Additionally, the adsorption properties of different phages can differ with ionic concentration, and there is a possibility of enhancement and/or irregular phage infection in the presence of some heavy metals, including nickel. Therefore, the influence of nickel concentration on bacteriophage abundance in wastewater is complex and depends on various factors, including the specific bacteriophage and the concentration of nickel present.
How does the presence of nickel affect the growth and survival of bacteriophages in wastewater?5 answersThe presence of nickel in wastewater can have an impact on the growth and survival of bacteriophages. The combined effects of V5+ and Ni2+ on metal-tolerant microbial isolates were studied, and it was found that Pseudomonas putida, a bacterial isolate, showed high resistance to both V5+ and Ni2+. On the other hand, Trachelophyllum sp., another microbial isolate, was highly sensitive to V5+ and Ni2+. The study also revealed that the combination of Ni2+ and V5+ resulted in a synergistic reaction, increasing their toxicity and impairing the microbial growth and survival. These findings suggest that the presence of nickel in wastewater can affect the growth and survival of bacteriophages, potentially impacting their ability to control bacterial contamination in these environments.
