This study analyzed the alteration of oral microbial composition in healthy subjects after using dextranase-containing mouthwash (DMW; Mouthwash formulation I) and dextranase-and-nisin-containing mouthwash (DNMW; Mouthwash formulation II). Eighteen participants were recruited and were randomly allocated to two groups: G1 (DMW user; n = 8) and G2 (DNMW user; n = 10). The subjects were instructed to use the provided mouthwash regularly twice a day for 30 days. The bleeding on probing (BOP), plaque index (PI), probing depth (PBD), and gingival index (GI) were analyzed, and saliva samples were collected before (day 0) and after (day 30) the use of mouthwashes. The saliva metagenomic DNA was extracted and sequenced (next-generation sequencing, Miseq paired-end Illumina 2 × 250 bp platform). The oral microbial community in the pre-and post-treated samples were annotated using QIIME 2™. The results showed the PI and PBD values were significantly reduced in G2 samples. The BOP and GI values of both groups were not significantly altered. The post-treated samples of both groups yielded a reduced amount of microbial DNA. The computed phylogenetic diversity, species richness, and evenness were reduced significantly in the post-treated samples of G2 compared to the post-treated G1 samples. The mouthwash formulations also supported some pathogens’ growth, which indicated that formulations required further improvement. The study needs further experiments to conclude the results. The study suggested that the improved DNMW could be an adjuvant product to improve oral hygiene.

“…The rod-shaped bacteria could be Geobacter or Enterobacter because they grow in an anaerobic environment, have exoelectrogenic nature, and a rod-shaped structure. 60,61 These microorganisms were reported for hydrogen production in previous studies. 25,62,63 The round-shaped microbial community observed on the anode surface could be Methanococcus, responsible for the conversion of produced CO 2 and H 2 into CH 4..…”

Evaluating the use of unassimilated bio‐anode with different exposed surface areas for bioenergy production using solar‐powered microbial electrolysis cell

The microbial electrolysis cell (MEC) is an emerging technology for bioenergy production using organic wastewater. Normally, a preassimilated bio-anode is utilized by the MEC to break down the organic content, but the formation and assimilation of microbial community at the anode surface is a time-consuming process. This study utilized a novel unassimilated Ni-foam anode for the first time in solar-powered MEC for bioenergy production. Synthetic dairy manure wastewater (SDMW) was used both as substrate and an inoculum in the solarpowered tubular MEC. The impacts of the exposed surface area of the bio-anode on bioenergy production were evaluated by utilizing two different separation techniques (rate-limited bio-anode -MEC and fully exposed bio-anode -MEC). The former technique achieves a maximum methane production rate of 30.35 ± 0.03 mL/L, 14.2% more than that achieved by the later mentioned technique (26.4 ± 0.05 mL/L). Hydrogen production was approximately 800 ± 5 mm 3 in both experimentations. The maximum generated current in the rate limited bioanode -MEC was 35.5 mA. Scanning electron microscope images confirmed the formation of rod-shaped along with round-shaped microbial communities on the anode surface, and, interestingly, round-shaped bacteria were also grown on the cathode surface. The bioenergy (H 2 and CH 4 ) produced using SDMW within first 13 days of operation, along with the formation of a microbial community, was a significant success in this area and has opened up many research opportunities for producing instant bioenergy from organic waste.

Aims: The work investigated the effects of plant seeds such as fenugreek (Trigonella foenum-graecum L.), wheat grains (Triticum aestivum L.), and hot red pepper (Capsicum annuum L.) which are traditionally used as natural food preservatives or at least to minimize the used concentrations of artificial preservative, meantime to serve as antibacterial agents against certain positive and negative gram bacteria such as Staphylococcus aureus ATCC 29213 and Enterobacter cloacae Enk1 LT592256 and the effectiveness of using germinated seeds in reducing bacterial growth. Study Design: The experiments were designed as one way completely randomized design. Place and Duration of Study: The experiments were carried out at the Regional Center for Food and Feed (RCFF), Agricultural Research Center, and Faculty of Agriculture Saba Basha, Alexandria University, Egypt. Methodology: The living bacterial cells in each treatment was estimated after 5 days of incubation at 25°C the total viable bacterial counts were determined using the plate count agar method. Microbial numbers in all samples were determined using serial dilutions also, determine the total flavonoids, antioxidant activity, and total phenol contents of the tested seeds and their germs. Results: Our results demonstrated that the maximum number of S. aureus bacteria in 10-1 on wheat germinated seeds extract at 1000 µl that is 290 CFU and the maximum number of E. cloaceae was 370 CFU was found in wheat non-germinated seeds at 500µl concentration, however, the highly inhibitory concentration of S. aureus 1000 µl was realized using non-germinated red pepper seeds extract (97.9%) and (92.9%) in the case of E. cloaceae bacteria. The maximum inhibition percentage was found with red pepper non-germinated seeds for (S. aureus) it was (97.9%) and for the (E. cloaceae) was (92.9%) under the concentration 1000 µl. The results showed that germs extract was less effective as an antibacterial agent than seed extract. S. aureus was more susceptible than E. cloacae. The use of hot red pepper seeds extracts then fenugreek extract was highly effective in reducing the growth of both the tested bacteria. Conclusion: Hot pepper and fenugreek extracts can be used as natural alternative preventives to control food poisoning diseases. Non Germinated seeds are most effective against studied bacteria growth.
