“…The model was considered statistically significant if the p-value was less than 0.05. 32 The lower value of P narrates the mutual interactions between the variables and indicates the importance of these variables in the model. 33 ANOVA analysis revealed five responses ranged from 14 mm to 17 mm for S. aureus, 14 mm to 18 mm for S. mutans, 14 mm to 18 mm for X. campestris, 13 mm to 16 mm for P. aeruginosa and 13 mm to 16 mm for C. albicans.…”

Objectives: The present work was carried out to check the capability of novel actinobacterium, Nonomuraea longicatena (VSM-16) for bioactive metabolite production and optimization of its process parameters by statistical and mathematical modeling. Methods: Response Surface Methodology (RSM) regression evaluation was done to fit the experimental data of each response with the aid of second order polynomial. Unstructured kinetic models had been developed for growth, substrate utilization and bioactive metabolite production (in terms of responses). Model based kinetic parameters were estimated and the profiles of bioactive metabolite production, substrate utilization and growth had been drawn. Results: The results have shown accurate interaction among process variables at optimized values of incubation time at 8-9 days, pH at 8-9, temperature at 30-31°C, concentrations of Mannitol at 2-2.2% and Biopeptone at 1.5-1.7% and the data have been effectively fitted into second-order polynomial models. Under these conditions, the responses (zones of inhibition) of various organisms Staphylococcus aureus, Streptococcus mutans, Xanthomonas campestris, Pseudomonas aeruginosa and Candida albicans have been also matched with experimental and predicted consequences. Conclusion: The zones of inhibition (responses) for the organisms had been also determined to be best fitted with experiment and model values.

“…The properties of scum biodiesel are within ASTM standards thus it can be productively used in diesel engines [45]. Biodiesel properties like specific gravity, kinematic viscosity, calorific value, flash point are determined using Fourier Transform Infrared Spectroscopy (FTIR) and they are within ASTM standard limits hence dairy scum biodiesel can be used in the diesel engine [46,47].…”

Research on and use of biodiesels for engines is growing continuously in the present era. Compression ignition (CI) engine performance for biodiesels of blends B20 from Acid oil, Mahua oil, and Castor oil is experimentally investigated. The engine performance analysis in the form of brake-specific fuel consumption, brakespecific energy consumption, brake thermal efficiency (BTE), exhaust gas temperature (EGT), and air fuel ratio are compared with diesel as base fuel. Emission characteristics like CO, CO 2 , NOx, and opacity are comparatively studied in detail for the considered biodiesels. The entire study is compared with the performance of engine when pure diesel is chosen as fuel. From the complete analysis it was observed that the BTE was higher for Acid oil and Mahua oil among the biodiesels used. And regarding CO emissions, Mahua oil showed lower effect than other biodiesels. Upto 6% increase in EGT of Mahua oil was obtained at no load and for other loads the percent reduced. For all the biodiesels the % enhancement in Co, CO 2 , and NOx was more than 60% at highest load compared with diesel.
