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 ...

The production of pediocin by Pediococcus acidilactici was comparatively studied in submerged and solid-state culture, using polyurethane foam particles soaked in commercial (MRS) and waste media with various supplements, where product concentrations were 15 times higher in MRS medium. For the solid state analysis, cultures were treated by successive compression and refilling of tubular minirea...

a basic alumina-spinel low cement castable (lcc) composed of sintered bauxite, reactive alumina, calcined alumina, calcined magnesia, microsilica, and high alumina refractory cement was prepared (castable a) to which 5% sodium hexa-meta phosphate was later added (castable b) to prepare samples for heat treatment at 110ºc, 900ºc, and 1400ºc. bulk density (bd), apparent porosity (ap), and cold cr...

the nanopowders of sno2, casno3 and ca2sno4 in the size rang of 5-70 nm have been prepared using solid-state reaction technique. the technique is convenient and inexpensive in comparison to the conventional routes of compound prepared and processing where, many steps of mixing and annealing are involved. formation of resultant compounds was explained on the basis of reaction taken place between...

objectives: the aim of this study was to compare the permeability of dentin after using diamond bur and er:yag laser. materials and methods: seventy-two recently extracted, intact, and restoration-free human permanent molars were used in this study. the samples were randomly divided into three groups of 24 each and class i cavities were prepared as follows. group 1: high speed diamond bur with ...

introduction: male urethral stricture is a complicated urologic disease that could be successfully treated using internal urethrotomy. laser internal urethrotomy has been used in many cases with favorable outcome in many studies. holmium: yag laser with its incisional properties on tissue is one of the laser types applied for internal urethrotomy. methods: we present a 19 year-old male with his...

Research was conducted to study the effects of biphasic anaerobic fermentation upon an organic fraction of municipal solid waste, and to observe the fate of heavy metals and pathogenic organisms in the acidogenic and methanogenic environments of the biphasic process. The high-solids (16 wt % solids) substrate was packed in a bench-scale, anaerobic, solid-state fermenter with amounts of lead nit...

background bleaching of traumatized discolored teeth is considered an important issue in esthetic dentistry. various methods have been introduced for bleaching, some of which may have adverse effects on soft or hard tissues of the tooth. objectives the objective of the study was to evaluate the effects of ktp laser bleaching on enamel of traumatized teeth. materials and methods a square of 36 m...

in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligan...
