This study presents production of α-amylase by Aspergillus oryzae in solid-state fermentation using 14 agro-industrial wastes as substrate. Enzyme production was growth associated and maximum titers (15095 U/gds) were obtained after 72 h when incubated at 30°C on wheat bran (initial moisture content, 60%; initial medium pH, 5). Enzyme titers increased significantly when the solid medium was sup...

Stuart's medium was originally prepared for use as a transport medium for gonococci (Stuart, 1946; Stuart, Toshach, and Patsula, 1954), but has now gained wide employment as a suitable transport medium for many micro-organisms (Stuart, 1956; Cooper, 1957; Gastrin, Kallings and Marcetic, 1968) including Trichomonas vaginalis (Stuart, 1956; Whittington, 1957; Odegaard, 1962). The original Stuart'...

Environmental pollution is the major problem associated with rapid industrialization, urbanization and rise in living standards of people. Efforts has to be made for controlling pollution arising out of the disposal of wastes by conversion of these unwanted wastes into utilizable raw materials for various beneficial uses. The problems relating to disposal of industrial solid wastes are associat...

The enzyme L-asparaginase has been proved to be efficient in treatment of Acute Lymphoblastic Leukemia [ALL] and Lymphosarcomas. The present paper discusses the studies carried out for the production of this enzyme from bacillus species. By study obtained optimization of medium, solid state fermentation by using cotton cake and wheat bran and submerged fermentation using distillery waste. a M2 ...

Experiments were done to determine if bacteria able to utilize phenanthrene as a sole source of carbon obtain the hydrocarbon directly from solid phenanthrene particles suspended in the medium or from the phenanthrene dissolved in the medium. Growth experiments were done in gas-tight fermentors completely filled with air-saturated, mineral salts solution with phenanthrene as the substrate. Gene...

Experiments were conducted in a liquid-solid circulating fluidized bed with different viscous liquids and particles to study the hydrodynamics, average solid hold up and solid circulation rate. The effects of operating parameters, i.e., primary liquid flow rate in the riser, auxiliary liquid flow rate, total liquid flow rate and viscosity of the liquid were studied for solids of different densi...

The linear governing equations of a transversely isotropic microstretch elastic solid medium are formulated and solved for surface wave solutions. The appropriate solutions satisfying the radiation conditions are applied to the required boundary conditions at the free surface of the halfspace of the medium. A frequency equation is obtained for Rayleigh surface wave in the medium. The non-dimens...

Angkak (red mold rice, red yeast rice, Chinese red rice) is a traditional Chinese medicine produced by solid-state fermentation of cooked non-glutinous rice with Monascus species. The secondary metabolite of Monascus species, monacolin K /lovastatin, has been proven to lower blood lipid levels. In this study, a co-culture of Monascus purpureus MTCC 369 and Monascus ruber MTCC 1880 was used for ...

[1] A technique for visualizing particle transport in the interior of a porous medium is presented. The technique, which includes the construction of a translucent medium and the use of laser-induced fluorescence for particle tracking, was used to examine the behavior of a dilute suspension of negatively charged, micron-sized particles in the interior of uniform glass bead packs during one-dime...
