The upsurge of emerging infectious diseases over the past few years especially from bacteria is a major global threat. The antibiotic used for the treatment purposes has adverse health effects. Hence, there is a need for novel natural alternates to overcome such issues. In this research work, the antibacterial effects of bio-inspired silver nanoparticles from Azadirachta indica bark were explored. Herein, the AgNPs were synthesized using aqueous extract of A. indica bark. The optimization of parameters was carried out using Box-Behnken Design ver. 12. Using response surface methodology the conditions for biosynthesis of small sized and uniformly distributed nanoparticles were optimized. The physicochemical characterizations of AgNPs were done by DLS, SEM, Zeta potential and FTIR. The DLS and SEM data revealed the average size of particles to be 76.35 nm and 30.6 nm respectively. FTIR analysis has shown the involvement of conjugated alkenes in the biosynthesis and capping process. In this research, the biological applications of AIB-AgNPs were also explored. The antimicrobial activities were determined by disc diffusion, Congo red agar and Crystal violet assays. The antimicrobial activity was found to be increased in a dose dependent manner. We have also looked into the mechanistic aspect of antibacterial activity. For this, cellular damages caused by AgNPs treatment were studied by membrane leakage analysis. The binding of AgNPs with bacterial cell and cellular leakage were visualized by SEM. Lastly, changes in the functional groups of membrane composition of bacterial cells were depicted by FTIR.

“…The method used to obtain the optimal cellulose, silica, and ZnO concentrations is the Box–Behnken design (BBD), which has fewer experimental trials than other methods. 74 Furthermore, BBD does not combine all factors at the highest or lowest levels at the same time; hence, it is effective in avoiding experiments under extreme conditions, which may lead to undesirable results. 75 The morphological structure and acoustic insulation properties of the aerogel were further investigated.…”

Noise pollution, which has become a major environmental issue in urban areas, can be minimized using acoustic insulation derived from cellulose–silica aerogel. The raw materials required in the process include waste newspaper-based cellulose, geothermal silica, and NaOH/ZnO solution. Therefore, this study investigates the effect of cellulose, silica, and ZnO concentrations on optimizing the sound absorption coefficient (SAC) using the Box–Behnken design (BBD). The results showed that the optimum conditions were obtained at 39.8578 wt % cellulose, 16.5428 wt % silica, and 0.5684 wt % ZnO. The impedance test for the cellulose aerogel and cellulose–silica aerogel showed SAC values of 0.59 and 0.70, respectively, and were characterized by XRD, FTIR, BET–BJH, SEM–EDX, and TG. The results of XRD and FTIR data indicate that the product was cellulose–silica aerogel, and the SEM micrographs showed that silica particles were attached to the fiber surface. Furthermore, type IV isotherms were observed in the cellulose–silica aerogel, typical of mesoporous materials. The presence of silica strengthened the aerogel structure, improved its thermal stability, and increased the surface area but decreased its pore size.

Background and PurposeIn regard to the biosynthesis of conjugated linoleic acid (CLA) and eicosapentaenoic acid (EPA) by some bacteria, the objective of this study was to evaluate the efficiency of solid-state fermentation based on soybean pressed cake (SPC) to produce CLA and EPA by Bifidobacterium lactis. The objective of this study was to evaluate the efficiency of solid-state fermentation based on SPC to produce CLA and EPA by B. lactis.MethodsProcess conditions including humidity, inoculation level, and temperature parameters were optimized by adopting the response surface methodology (RSM) method (response surface method) and the design expert software. Accordingly, a homogeneous SPC paste substrate at 60, 70, and 80% humidity was prepared with different inoculation levels at 30, 37, and 44°C to assess the strain behavior. The introduced SPC consisted of 60% humidity, 2% inoculation level at 37°C, and 60% humidity, and 4% inoculation level at 30 and 44°C; it also included 6% inoculation level at 37°C, 70% humidity at 2% inoculation level, at 30 and 44°C, and 4% inoculation level at 37°C. Also, SPC with 80% humidity at 2% and 4% inoculation levels, and at 30 and 44°C was obtained. To confirm the accuracy of the conditions, an experiment was conducted according to the defined requirements.ResultsThe results were compared with the predicted data, which showed a significant difference. Under optimized conditions, with an inoculation level of 4% on the SPC medium with 70% humidity and at 37°C, B. lactis strains could yield 9cis-, 11 trans-linoleic and eicosapentaenoic at 0.18 and 0.39% of the total fatty acids.ConclusionSo, the potential benefits of using SPC as an inexpensive substrate for the commercial production of CLA and EPA should be noted.
