The residue from desulfurization and denitrification of exhaust gas treatment process with pyrolusite ore as absorbent is regarded as a potential source of iron and manganese. In this study, an extraction process is proposed for recovery of iron and manganese with ammonium sulphate roasting followed by sulphuric acid leaching. Firstly, the conversion mechanism was analyzed through mineral phase...

Corynebacterium glutamicum is an industrially important microorganism used for amino acids production. The present work describes the production of L-lysine from Corynebacterium glutamicum IIB-C9 through submerged fermentation process. Fifteen fermentation media were screened in this study for L-lysine production. Out of these fifteen media, FM:13 was found a best one for maximum production of ...

Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction  and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essen...

Vibrational spectroscopy can give useful informa tian, both structural and dynamical, about phase transitions in molecular crystals. In particular, the data concerning the mechanism of the transformation at molecular level can be obtained. This is illustrated by examples of pure van der Waals crystals such as 3,5-dichloropyridine and 4-methylpyridine, hydrogen bonded malonic acid, inorganic fer...

In this paper, we have proposed a simple method to covalently conjugate biotin to magnetic nanoparticles, which can be targeted to the tumour sites by using pretargeting approach with avidin or streptavidin. Magnetic nanoparticles of manganese ferrite were synthesized by alkaline coprecipitation of ferric chloride hexahydrate, ferrous sulphate heptahydrate and manganese sulphate monohydrate usi...

A lipase producing Acinetobacter haemolyticus TA106 was isolated from healthy human skin of tribal population. The maximum activity of 55 U/ml was observed after medium optimization using the "one variable at a time" and the statistical approaches. The optimal composition of the medium was determined as (% w/v or v/v): tryptone--1, yeast extract--0.5, sodium chloride-1, olive oil-1, Tween-80 1,...

The study was carried out for two consecutive years (2005-06 to 2006-07) to evaluate the wheat response to five different levels (0, 4, 8, 12 and 16 kg ha) of manganese (Mn) alongwith 150-100-60 kg NPK ha application. The experiment was laid out in randomized complete block design (RCBD) with three repeats under irrigated conditions at Agriculture Research Farm Karor, District Layyah. NPK was a...
