Article
Full-text available
Beauveria bassiana, one of the most common entomopathogenic fungi, has been isolated, pre defined and characterized in-house from soil of tea cultivation area. Experiments have been performed to verify the presence of chitinase as intracellular metabolite and its release as extracellular product rendering the spores with biopesticide activity. Alth...
Article
Extraction of Crotalaria juncea (Sunn hemp) oil from its seeds is important to study because of its proven promising clean fuel characteristics. Soxhlet based solvent extraction with some modification has been tried to extract the oil. In a fluid-solid mass transfer system, where, solids are present as packed bed, dynamic behavior of bed can be des...
Article
Crotalaria juncea (Sunn hemp) is one of the popular fiber crops of India. Its seeds contain appreciable amount of bio-oil which has promising fuel characteristics. Batch kinetics of extraction of C. juncea oil has been carried out and some pseudo-kinetic models (two-site kinetic desorption model (TSKDM), one-site kinetic desorption model (OSKDM) an...

In the present investigation entomopathogenic fungi, Beauveria bassiana was isolated from its soil source. Selective antibiotics with regulated dose were used to isolate the targeted spore in pure form. Chemotaxonomic studies involving lactophenol cotton blue staining, field emission scanning electron microscopy and the 28S rDNA gene sequencing met...
Article
A novel three-phase partitioning (TPP) based extraction method is used to extract oil from Crotalaria juncea seeds, having potential fuel value. This study reports an efficient alternative extraction technique, as compared to the conventional soxhlet extraction, that can be carried out at room temperature. Partitioning of oil is studied using diffe...

Full-text available
An innovative method for the extraction of vegetable oils, from Crotalaria Juncea seeds, was developed, using suitable solvent in a modified Soxhlet apparatus. The present study describes the general extraction mechanism in modified Soxhlet apparatus and change of mass transfer extent within fixed duration with the change of the shape of packed bed...

Overall decomposition of water into hydrogen and oxygen in presence of a heterogeneous photocatalyst has received prodigious attention due to its potential for the production of clean and recyclable hydrogen energy. However, most of the efficient photocatalysts developed till date, works primarily on ultra-violate range of light. To develop photoca...

Background Chemostats are characterized with increase of viscosity of reaction broth and is prone to non-ideality. The present study is mainly focusing on the identification of non-idealities namely dead zone and bypassing of a real chemostat or continuous stirred tank bioreactor. ResultsExperimental studies were conducted both in non-reactive mode...
Article
Oil extraction from crushed Crotalaria Juncea seeds is done by standard solvent extraction method using a modified Soxhlet apparatus. Parameters such as size fractions of the crushed seeds, extraction time, aging of seeds, choice of solvents and use of co-solvents along with the primary solvent are optimized in order to enhance the yield of bio oil...
Article
Screen-printed electrodes (SPEs) containing immobilized acetylcholine esterase (AChE) enzyme were used for the electrochemical determination of organophosphorous (OP) and carbamate pesticides. The extent of AChE deactivation by the pesticide was determined in the presence of acetylcholine (AChCl) substrate. The unique nature of this approach lies i...
Article
A mathematical model has been developed by performing a non-linear regression analysis to simulate the fermentation process of glucose to lactic acid by considering the product-inhibition situation and substrate requirement for cell maintenance. To account for such an effect a toxic power (n) and a cell-maintenance factor (m) have been incorporated...
Article
The kinetic behaviour of a heterogeneous branched bienzyme system of beta-D-glucose oxidase and hexokinase on glucose has been studied. In this sequence, hexokinase is inhibited by its product glucose 6-phosphate and also by D-gluconic acid produced from the parallel enzymic reaction of glucose oxidase. Effect of glucose concentrations on the produ...
