The site is secure. Owing to their selective nature, bacteriophages are prospective in targeted wastewater disinfection.

Other potential applications include the removal of biogenic malodour and the mitigation of corrosion in sewerage pipelines. Nevertheless, its applications are ridden with challenges, the most prominent of which is scaling up. Towards that end, effective methodologies are required for dispersing phages into wastewater.

The study describes a device arbitrarily named Lytics Broadcasting System. In principle, the device contains phages that can be continuously dispersed into wastewater. The modified version is called Bacteriophage Amplification Reactor, which operates with both phages and their respective hosts, ensuring continual production and dissemination of phages.

Both prototypes utilize 0. A reduction of 3—4 log was achieved with both the prototypes after 48 h of operation in 1 L of augmented synthetic sewage. This study aims to provide a framework for the development of scalable prototypes of Lytic Broadcasting Systems for real-world wastewater applications. Classical phage therapy has become a valuable alternative therapeutic tool in the growing face of antibiotic resistance with a broad range of biocontrol applications.

Currently, the application of bacteriophages is primarily employed in clinical conditions such as cystic fibrosis [ 1 , 2 ], burn wound infection [ 3 ], impaired wound healing and infection of dental root canals [ 4 , 5 ]. However, there has been a recent surge in the application of phages in the field of food [ [6] , [7] , [8] ], agriculture [ 9 , 10 ] and aquaculture [ 11 , 12 ]. In recent times, the concept of the application of phages in the treatment of wastewater is gaining traction [ [13] , [14] , [15] ].

However, residues in treated water from these compounds and their disinfection-by-products may pose a risk to humans and aquatic ecosystems [ 16 ]. Poor specificity of these chemical methods aggravates the problem further by being detrimental to the activity of other desirable bacteria involved in the natural biodegradation of wastewater. On the other hand, wastewater treatment practices that avoid or reduce the use of chemical disinfectants, such as ozone and UV irradiation, are limited by reliability, cost, and their applicability to large-scale operations [ 17 ].

Considering these challenges, the application of natural disinfection processes could represent a more viable solution to improve the specific removal of infectious bacterial pathogens from wastewater [ 18 , 19 ].

In this milieu, bacteriophages- the bacterial viruses with several ideal characteristics viz. Recently, wastewater and wastewater treatment plants WWTPs are considered important reservoirs of bacteria harboring potentially transferable antibiotic-resistance genes into the environment [ [21] , [22] , [23] ]. Since WWTPs treat sewage from different sources, they facilitate the horizontal transfer of genes among different pathogenic bacterial species [ 24 ].

Removal of antimicrobial-resistant strains AMR in conjunction with effective monitoring would help in containing the spread of infection by these multidrug-resistant superbugs. Other than infection, malodour and corrosion of sewers are the major aspirational, operational, and maintenance problems with the wastewater treatment facilities. One of the major sources of foul odour is hydrogen sulfide produced in wastewater by sulphate reducing bacteria SRBs.

Selective elimination of infectious organisms and biogenic malodour mitigation could be effectively employed in wastewater treatment facilities by phages as discussed in our previous study [ 25 ]. An added advantage is that phages can minimize the selective pressure imparted by residual antibiotics to AMR bacteria and their subsequent propagation in wastewater. Nevertheless, phage-based methods should be amenable to scale-up and compatible with different settings, such as centralized and decentralized treatment systems.

Central to that is their ability to disseminate phages, maintain a high titre in wastewater, and their ability to withstand harsh conditions. Few methodologies that can be adopted for the dissemination of bacteriophages include immobilization [ 26 , 27 ], encapsulation [ 28 , 29 ], and use of liquid suspensions, for continuous production and dissemination of phage particle [ 19 ].

With phages immobilized or encapsulated, the major drawback is the complexity of the process. It requires sizeable time, potential loss of phage titre, and considerable resources to execute [ 27 ]. Nevertheless, such a direct application of phage liquid preparation would suffer from the disadvantage of being energy intensive owing to their off-site production and frequent addition.

Hence it is imperative to develop an energy-neutral system for phage dissemination along with effective monitoring techniques. In an ideal system, phages would be held in a contraption that could also hold their respective hosts and such an interface could be used to transmit them selectively without the use of energy.

Bacteriological membrane filters can effectively serve as an interface for selective diffusion of phages while simultaneously preventing infiltration of the bacterial hosts.

This study shows that 0. Phage particles are selectively and passively dispersed into synthetic sewage due to the limiting pore size and lack of pressure. Another prototype, the Bacteriophage Amplification Reactor BAR-LBS , holds both phages and their host cells, thus serving as a generator of the lytic agents phages for continuous dispersal of phages into the simulated sewage through a 0.

Two prototypes were built to evaluate the potential for field applications. Multi-drug resistant clinical strain of Salmonella enterica was used in the study. Using 0. Subsequently, we also tested the possible permeability of bacteria through the membrane.

Bacteria I. The first set-up includes a 50 mL sterile conical centrifugation tube to hold phage lysate or its respective bacterial host. To secure the 0. A modified LBS with membrane secured onto the boiling tube was used in large-scale experiments 1 L to monitor the production of H 2 S since it can be accommodated in a conical flask and its mouth hermetically sealed Fig.

The sample at each time point was diluted in the SM buffer and the dilutions were then used to determine the phage titre against the bacterial host. Similarly, the bacterial infiltration rate was determined in the same manner. The setup was continuously mixed as mentioned earlier and the sample of 1 mL was taken for the same amount of time as that of the phage infiltration experiment.

The collected sample was diluted in 0. Subsequently, for rapid detection, the sample was also subjected to a resazurin-based fluorometric assay to check for the presence of the infiltrated bacteria, if any.

In brief, LBS was prepared in a sterile 55 mL boiling tube comprising 40 mL of phage lysate with a titre of 5. We then affixed sterile 0. Following this, the tubes were inserted into flasks containing Salmonella OD nm 2.

Samples were collected beforehand from both control and test sets in order to determine the number of bacteria at 0 h. The experimental setups were incubated at room temperature for a period of 48 h. Subsequently, 1 mL of the sample was also collected from each set up to determine the bacterial cell viability count and phage titre. Bacteriophage amplification reactor was developed within an LBS by feeding the system with 40 mL mixture containing the phage and its respective host in this case, Salmonella enterica 1.

The control consisted of an LBS charged only with the bacterial host supplemented with phage broth. As mentioned in section 2. The sample was mixed to avoid sampling errors and the flasks were made airtight using parafilm to ensure H 2 S production.

The samples 1 mL were taken at 0 h and 48 h to be plated on SS agar from both control and test and the corresponding titre of phage in the test was also determined. All the experiments were analyzed using GraphPad Prism Version 8. The membrane 0. This was observed as a clear zone of lysis over the bacterial lawn on removing the membrane while the control SM buffer did not show any effect on the bacterial growth Fig. The selectivity of the membrane was tested using bacteria where the liquid bacterial culture failed to diffuse through the membrane showing no growth in the LB agar after incubation for 24 h, rather the growth was observed on the surface of the membrane Fig.

The selectivity of 0. Passive diffusion in the absence of pressure could serve as an ideal characteristic in the development of an energy-efficient lytics broadcasting system. Conventional wisdom indicates that pressure above 1 bar is required to extrude the contents across the membrane [ 34 ]. However, the current study reiterates the slow, effortless, and passive diffusion of submicroscopic particles including viruses like phages.

The plate shows the zone of lysis indicating passive infiltration of phages through the membrane I , while the control SM buffer did not show any indication of passage through the membrane II.

The absence of bacterial growth after removing the membrane indicates selective permeability of only phages across the membrane. The rate of infiltration of phages through 0. We also showed the inability of the bacteria to infiltrate through the membrane, as there was no bacterial growth in the plate assay as well as in the resazurin assay even after 24 h, ensuring successful filtration of the host bacteria by the membrane Fig.

This experiment corroborates our earlier experiment on the selectivity of 0. This particular model is least affected by membrane biofouling issues, as phages have already been reported to act as an antimicrobial agent against membrane biofouling in ultrafiltration units [ 31 , 35 , 36 ]. The well plate shows the absence of bacterial viable activity by resazurin indicating the absence of infiltration of bacteria from the LBS membrane into 0.

LBS's potential for disinfecting bacteria of interest in 1 L synthetic sewage indicates its utility in eliminating antimicrobial-resistant and infectious bacteria like Salmonella enterica , which also produces biogenic H 2 S that may contribute to malodourous wastewater. The system was efficient in reducing the bacterial count by 4-log in 48 h when compared with the control where the LBS was charged only with phage broth Fig.

The control set-up had an expected decrease in parameters, viz. As opposed to the parameter control mentioned above, the test setup revealed an increase.

In both setups, volatile organic compounds and pH were the same, however. This outcome is consistent with the observation that, in the control set-up, the target organism's load remained higher due to the absence of lysis by bacteriophages.

However, in the test set-up, the infiltrated phages upon lysing the bacterial cell 4-log reduction resulted in reduced bioremediation and an increase in the organic content, as reflected in the above-mentioned chemical parameters. Photographic images show a clear difference in turbidity as well as lead sulphide deposition on the lead acetate strip, an indication of reduction in the H 2 S production between the control left and the test right setup of an LBS.

The lead acetate strip showing a reduced lead sulphide precipitation between the phage treated sample right and the untreated control left after 48 h using an LBS. Chemical characteristics of synthetic sewage from both control and test setups of LBS after 48 h of treatment. The system can be further improved by employing a cocktail of one or more phages that can undoubtedly impact the performance of the LBS positively while translating into real wastewater treatment. The scope of the study involves targeting specific pathogens that can contribute to malodour and to an extent infection to both humans and animals, especially the enteric bacteria.

Moreover, such a system can make the process of application of phages easier and far more user-friendly for the workers in the wastewater treatment facilities, unlike other chemical methods [ 37 , 38 ].

Will Ayaka in a swimsuit make up for my tardiness? I am curious whether this development will release Hikari from his stasis or further push him into indecisiveness. Other than that I have to say that Kaname is really starting to grate on me. The dude needs to learn to give up. When you have a show as light-hearted as Sakura Trick I guess you can kind of ignore the unspoken tragedy of things like this. Pretty standard episode of InaKon this week with several good things happening but also several bad things. In a vacuum if I knew they were going to add a character with his looks and his mannerisms to the show in episode eight I would have guessed that it would be an unequivocal disaster but InaKon actually does a very good job of balancing the humor and the drama here.
