The objectives of this work were to develop a new technique for lycopene microencapsulation by spray drying using dehumidified air as drying medium and to determine optimum operating conditions. A two-step optimization procedure was used. The encapsulation variables were selected in accordance with the PlackettBurman experimental design and were further optimized via response surface methodolog...

Arachidonic acid is an essential fatty acid in human nutrition. In the present study, production of arachidonic acid by Mortierella alpina CBS 754.68 was evaluated in submerged fermentation. The fermentation variables were selected in accordance with the PlackettBurman (PB) design and further optimized via response surface methodology (RSM). Five significant variables, namely glucose, yeast ext...

Lactic acid is one of the functional and valuable compounds utilized in food, pharmaceutical, and chemical industries while Poly lactic acid (PLA) is a biodegradable polymer that has a variety of applications. In recent years, microbial conversion of renewable raw materials has become an important objective in industrial biotechnology. Among many raw materials available, tapioca starch is consi...

Exo-polysaccharides like dextran produced by Weissella sp. have a wide range of applications in the food, pharmaceutical and other industries. This biopolymer and its derivatives like iron dextran, clinical dextran are rapidly emerging as a new and industrially important products. Dextran a polymer of glucose is produced using sucrose rich media with nitrogen source. It also requires efficient ...

Gloriosa superba is a medicinal plant used in traditional medicine for the treatment of various diseases. The tuber of Gloriosa superba is a rich source of colchicine which is used for the treatment of gout, cirrhosis and also used in plant breeding studies to produce polyploidy. Optimization of various extraction parameters using response surface methodology (RSM) was performed to assess maxim...

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...

The present study was undertaken to study the statistical optimization of medium components for improved Indole-3acetic acid (IAA) production by Pseudomonas aeruginosa. Colorimetric analysis showed maximum IAA (132 μg mL-1) in the medium supplemented with tryptophan (0.5 g L-1). The maximum production was achieved after 96 h of incubation. Yeast extract, tryptophan and EDTA were identified as s...
