The main objective of the study is to enhance the mevastatin production using Plackett-Burman (PB) and central composite design (CCD) by Aspergillus terreus in submerged fermentation (SmF). Eight nutrients were chosen for a PB design with 12 experimental runs. A maximum mevastatin production of 170.4 mg L-1 was obtained in PB design. Response surface methodology (RSM) is a sequential procedure ...

In this study, the sorption of Malachite green (MG) on Hydrilla verticillata biomass, a submerged aquatic plant, was investigated in a batch system. The effects of operating parameters such as temperature, adsorbent dosage, contact time, adsorbent size, and agitation speed on the sorption of Malachite green were analyzed using response surface methodology (RSM). The proposed quadratic model for...

The upcoming technological breakthrough in the cropping system will offer a more detailed insight into soil-to-plant, man-to-soil, and man-to-plant impacts, thus improving forecasting ensuring efficient in-field management. This study presents various on-the-go sensing procedures which were conducted order to evaluate quality of spatial estimations soil physical properties such as compaction, m...

background and objectives: discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, congo red, by a fungal isolate, aspergillus niger hm11. materials and methods: centra...

In recent years we have seen interest in Tibetan kefir grains (TKG) for production of fermented milk beverages. The article presents the results work on expanding range beverages based TKG, studying influence fermentation conditions quality characteristics and their shelf life. possibility optimization is shown. Using method Central Composite Design (CCD), response functions were obtained form ...

The pressure swing adsorption (PSA) process was used to capture carbon dioxide (CO2) from the flue gas of a coal-fired power plant reduce CO2 emissions. Herein, captured using PSA for at least 85 vol% purity and with other exit stream more than 90 N2 purity. extended Langmuir–Freundlich isotherm calculating equilibrium capacity, linear driving force model describe kinetics. We compared results ...

To meet the present needs of concrete consumption, it is need hour to discover different alternatives and unique techniques. By Incorporating latest trends, Polymer Concrete (PC) Fibre-Reinforced ­Concrete (FRC) are being used improve strength concrete. It proposed produce M30 grade Fibre Reinforced (FRPC) with help Polyester Resins (PR), Polypropylene Fibres (PF) Recycled Waste Plastics (RWPA)...

Dispersive liquid–liquid microextraction (DLLME) combined with inductively coupled plasma-atomic emission spectrometry (ICP-AES) was applied for the determination of lead in different environmental water samples. Ammonium pyrrolidine dithiocarbamate (APDC), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. The effective parameters, such...

Experimental designs were applied for optimizing media and process parameters for hydrogen production from maize stalk hydrolyzate by a newly isolated facultative strain.Plackett-Burman design was used to identify the significant components and using this method the media components - glucose, yeast extract, malt extract, peptone, and NaCl were identified as signi...
