Lime stone is the most common type of rock found on earth's surface. During the process of manufacture, quick lime is produced in many sizes in the kilns. Large sized pieces find use for construction purposes, food processing and many more however, finer fractions find less utility. Such material is mostly dumped for earth filling. Suitability of such waste was evaluated as it was found to be rich source of Calcium. Lime stone processing waste was further processed to find out which fraction could be used to prepare mineral supplement for livestock as it was a rich source of Calcium. As physical attribute of materials affect its solubility and bioavailability of the element. The waste fraction of industry was fractionated into 3 fractions viz with particle size >1 mm, 0.25-1 mm and <0.25 mm. Solubility of each fraction was observed in water and in HCl (0.04N, 0.08N, 0.16N). Salts of Calcium (Calcium Chloride, Rock phosphate, Di Calcium phosphate, Tri Calcium phosphate, Calcium hydroxide and Calcium sulphate) were also tested for their solubility. Solubility of limestone fractions improved with decrease in particle size. Solubility of salts and fractions of limestone waste improved with increase in normality of HCl. Results indicate significant (P≤0.0001) increase in solubility of lime stone fractions in water with decrease in particle size (8.62, 20.20, 32.50%). Increase in solubility increased pH significantly (P≤0.05) from slightly acidic 6.27 with higher particle size to 7.36 with lowest particle size. The results reflect that fractions with lower particle size have an advantage due to their solubility in dilute HCl and even with water as solvent and they have excellent flow property, which could prove useful for preparation of mineral supplements as well ease mixing in the feed mixtures. Thus major fraction out of the limestone waste can find its use as a mineral supplement in the animal feed industry. Source

We report that the bgl operon of Escherichia coli, encoding the functions necessary for the uptake and metabolism of aryl-β-glucosides, is involved in the regulation of oligopeptide transport during stationary phase. Global analysis of intracellular proteins from Bgl-positive (Bgl +) and Bgl-negative (Bgl -) strains revealed that the operon exerts regulation on at least 12 downstream target genes. Of these, oppA, which encodes an oligopeptide transporter, was confirmed to be upregulated in the Bgl + strain. Loss of oppA function results in a partial loss of the growth advantage in stationary-phase (GASP) phenotype of Bgl + cells. The regulatory effect of the bgl operon on oppA expression is indirect and is mediated via gcvA, the activator of the glycine cleavage system, and gcvB, which regulates oppA at the posttranscriptional level. We show that BglG destabilizes the gcvA mRNA in vivo, leading to reduced expression of gcvA in the stationary phase. Deletion of gcvA results in the downregulation of gcvB and upregulation of oppA and can partially rescue the loss of the GASP phenotype seen in ΔbglG strains. A possible mechanism by which oppA confers a competitive advantage to Bgl + cells relative to Bgl - cells is discussed. © 2012, American Society for Microbiology. Source

Background: WHO has recently renamed odontogenic keratocyst as keratocystic odontogenic tumour (KCOT) depending on its tumour like behaviour. Aim: To quantitate and qualitate different types of collagen fibers in KCOT using picrosirius red stain under polarising microscopy and to correlate with different radiographic patterns of KCOT to elucidate its biological behaviour in order to determine whether all KCOTs behave like a tumour. Materials and Methods: Sixty histopathologically confirmed cases of KCOT were selected and stained histochemically using picrosirius red and examined under polarising microscope to evaluate colour of collagen fibers in the wall. Radiographic analysis of all the cases were also carried out and correlated with type of collagen of fibers. Results: Greenish yellow collagen fibers were present statistically significantly more in multilocular KCOT and KCOT with multiple radiolucencies (both syndromic and non-syndromic) as compare to unilocular whereas orange red were significantly more in unilocular variety. Syndromic variety showed significantly higher number of greenish yellow collagen fibers than non-syndromic variety. Conclusion: Quality, organization and packing of collagen fibers of unilocular type is different than other radiographic patterns which accounts for difference in biological behaviour of these lesion, so we conclude that aggressive treatment should be reserved for selected cases.

An experiment was conducted to evaluate mineral supplement prepared using limestone waste. Limestone waste (dust) available was collected from industries processing Lime. It was sieved with mesh size upto 1 mm and the material was used as source of Calcium for preparation of the mineral supplement. A total of 121.98 kg of mineral supplement was prepared for the feeding trial.Milch animals of similar parity (3-4) were selected from the field area in Bikaner district and supplemented with mineral supplement. The animals were milked twice a day, during morning and evening after interval of 12 hours. In the first phase 8 animals (2 each owned by each farmer) were divided into two groups of 4 each. All the animals were provided a mixed diet of wheat straw and groundnut fodder (1:1) along with Cottonseed cake 5 kg which was soaked in water for 3-4 hours before mixing with equal quantity of dry fodder (wheat straw and groundnut fodder). One animal of each farmer was offered mineral supplement and the other served as control. In the first phase mineral supplement was offered in the treatment group (along with the concentrate) for a period of 56 days. Observations on milk production were recorded daily during the period. The study was continued in second phase with one animal to observe long term effect of the supplement for which one cow was provided mineral supplement for a period of 150 days. Since all the animals were not similar in milk production, fixed quantity of 50g/h/d was given in two equal doses of 25g each. Data reflected that 51.1% of milk was produced during morning and 48.9% during evening milking. Feeding of supplement had a significant effect on milk production per cow. Milk production was sustained at an higher level due to feeding of mineral supplement which otherwise would have decreased due to higher demand of Ca and P for milk secretion. It could be concluded from the studies that cheaper source of Calcium as limestone dust could be used effectively for preparation of mineral supplement. Feeding of mineral supplement containing Lime stone dust did not have any negative effect on animal health. Its feeding consistently improved milk production and sustained it for a long period in cattle. Thus limestone waste could serve as a useful ingredient for production of mineral waste for livestock. Milk production was similar at the start of experiment. Differences in milk production were observed which increased gap among the groups. Significantly higher (P≤0.01) milk production was observed in animals supplemented with mineral mixture. Week had a significant effect on milk production per cow. Milk production was sustained at a higher level due to feeding of mineral supplement which otherwise would have decreased due to higher demand of Ca and P for milk secretion. Data reflected that 51.1% of milk was produced during morning and 48.9% during evening milking. To study the long term effect of mineral supplementation observations on milk production were recorded for nearly 150 days with one farmer. It was observed that milk production follows a zig zag curve. Considering that the management factors were optimized, results on long term feeding of supplement containing lime stone waste indicated that milk production could be sustained for a long period as it dropped slowly to a tune of 0.006kg/d after obtaining peak, thus reflecting that it had positive effect.

The continuous use of fuels like petroleum is recognized as unsustainable because of their natural exhaustion and contribution to the pollution in the environment. Not only for the environmental perspective but also for the economic sustainability, we necessarily need to develop alternative, renewable and pollution free fuels. Harvesting energy from the sun (solar energy), earth (geothermal energy), water (hydropower), or wind are few of the alternative and renewable energy sources. It has been well appreciated that fuels, such as ethanol, butanol, methane and hydrogen can be produced by microorganisms. But by using bacteria in a microbial fuel cell (MFC), electricity can be extracted from wastewater, converting organic material in the waste water to electricity using bacteria, leaving behind clean drinking water in the process (bacteria are appreciated as electricigens). Harvesting electricity with microbial fuel cells can proficiently convert organic wastes, renewable biomass and even mud into electricity and harmless byproducts. This capability offers the potential for using bacteria (or their components) to generate electricity at low cost while transforming industrial, domestic, and farm toxic pollution. This is an exciting aspect for human kind around the world who lacks adequate sanitation and resources to clean up toxic waste. Though the MFC technology is not yet well developed to produce substantial quantities of energy in a cost effective way, the area reviewed in the present communication requires more research and is highly prospective.
