Beta Galactosidase

Biotechnological processes with microalgae with the aim to achieve high biomass yields must choose the appropriate nutrients and physicochemical parameters, taking into account the specific characteristics of each species to determine the basic needs for its growth. In the present study, the better growth condition of Chlorella sorokiniana IPR 7104 was optimized to reach the maximum beta-galactosidase production. The cheese whey concentration (%), temperature (˚C) and pH were factors investigated and a Box-Behnken Design (BBD) approach was implemented using Statistica 7.0 software. We observed that the cultivation condition to Chlorella sorokiniana IPR 7104 was the heterotrophic, which showed the major enzymatic activity, consequently a lower residual lactose content. Under heterotrophic conditions (without light) the β-galactosidase activity increased linearly until the 8th day. Biomass production grew linearly on the 12th day. The microalgae consumed 89.6% of lactose in 3 days, showing a high capacity to metabolize this disaccharide, through β-galactosidase synthesis. The maximum β-galactosidase production by Chlorella sorokiniana IPR 7104, in heterotrophic conditions and using cheese whey as carbon source, is obtained using the following conditions: 30°C temperature, concentration of ethanol at 20% and time of 4 min.

A significant effect of weather conditions on crop biomass yields was observed in various production areas during the last decade. Starting with the municipality of Březník within the period of 2007–2011, the present article studies the relationship between weather conditions and the volume of municipal residue biomass (MRB). A statistically significant impact of rainfall level on MRB production has been demonstrated. The development of biodegradable municipal solid waste collection in the municipality of Březník has also been described and evaluated.

India is a developing nation and is dependent on its natural resources for growth and development. Water, being one of the vital natural resource, must be used judicially for the sustainable development. Present study focuses on the analysis of physicochemical parameters (pH, Turbidity, Alkalinity, Total Hardness, Total dissolved solids, Conductivity, Chloride, Sulfate, Fluoride contents) of ground water and surface water in Kota City (Rajasthan). The study shows the adverse impact of exploitation and urbanization on water resources of Kota City (Rajasthan). Some physicochemical parameters exceed the desirable limits as defined by WHO and Indian Standards in the selected sites. The level of pollution in ground water and surface water of Kota City is increasing due to urbanization.

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms.

Activated Sludge Systems

This study quantified the kinetic differences in microbial communities isolated from completely mixed activated sludge (CMAS) systems that were operated either with or without an aerobic selector preceding the main reactor. A new respirometric method was employed that allowed the determination of biodegradation kinetics from single oxygen consumption curves, thereby minimizing physiological changes to the examined communities during the assay. Results indicated that increased values for Ks and μmax for acetate, phenol, and 4-chlorophenol degradation were measured in the CMAS system operated with a selector. The biomass yields on acetate, phenol, and 4-chlorophenol were very similar in both systems. These findings indicate that the operation of CMAS systems with aerobic selectors may result in the selection for degrading populations with higher Ks and μmax values for both biogenic and xenobiotic organic compounds, and that substrate storage in the selector only partially contributes to increased substrate removal rates.

Background: Sneha Kalpana is one among the several highly established Kalpana of Ayurvedic system of medicine. Many types of Taila Kalpana are mentioned in Ayurvedic classics and used effectively in therapeutic practice. Tila Taila is the most commonly using Taila. However Narikelataila, Erandataila, Sarshapataila, etc, are also used in special conditions. It is interesting to note that certain preparations are available in the market based on both TilaTaila and Narikela Taila. This is an attempt to comparatively evaluate the formulation Dhutturadi Taila prepared in Tila Taila and Narikela Taila as the bases. Dhutturadi Taila mentioned in Sahasrayogam is taken for the present study. Objectives: To comparatively analyse Dhutturadi Taila samples with classical and advanced analytical techniques. Materials and Methods: Dhutturadi Taila was prepared using two media i.e. Narikela Taila and Tila Taila. Both Taila samples were comparatively analysed with suitable physicochemical parameters and advanced instrumental methods of analysis. Conclusion: As per the existing result it seems that more amount of marker components are extracted into Tila Taila medium when compared with Narikela Taila.
