für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Rock phosphate depletion in the world can lead to many devastating problems, mainly to the agriculture and related sectors. More than 75% of synthetic phosphate fertilizers undergo rapid precipitation and fixation after the application to soil. Furthermore, most of the soil phosphorus is not available for plant uptake. Thus, phosphorus has become a limiting nutrient for crops. Renewable phosphorus sources are required in order to provide substantial supply of phosphorus for crops. Microbial activity may release the insoluble phosphorus accumulated in soils and make them available for plants. Besides, bacteria may increase the soil fertility and promote the plant growth. Therefore, phosphorus based bio-fertilizer application to soil has been the main focus of many farmers and researchers for the past few years. This book has highlighted the analytical methods of isolating and screening mineral phosphate solubilizing bacteria that can be applied to acidic and alkaline soils. It should furnish you with some scientific background on mineral phosphate solubilization as well. This book should be beneficial to those who are interested in organic agriculture and biofertilizer production. ····· 1036188933

The satellite-like alphasatellites (previously known as DNA 1) were first identified in 1999 and were shown to be associated with the majority of begomoviruses (family Geminiviridae) that require the satellite molecule now collectively known as betasatellites. Virus-induced gene silencing (VIGS) is a powerful reverse genetics tool for application in functional genomics. The alphasatellite-based VIGS vector was shown to be functional by silencing expression of GFP in 16c plants and magnesium chelatase. In addition, the alphasatellite vector was shown to be useful as a gene expression vector. An analysis of tomato plants from Oman exhibiting severe leaf curl symptoms showed the presence of Tomato yellow leaf curl-Oman (TYLCV-Om), a virus previously shown to be present in tomato in this country, a new recombinant begomovirus species, for which the name Tomato leaf curl Oman virus (ToLCOMV) is proposed, a betasatellite (tobacco leaf curl betasatellite (TbLCB) and an unusual alphasatellite.

There is no doubt that the multiple interacting physical, chemical and biotic characteristics of an aquatic ecosystem play an important role in influencing the production and distribution of its communities. Accordingly, changes in these characteristics lead to qualitative and quantitative changes in the planktonic composition. Despite the severe problem caused by algal blooms, the phenomenon has received limited attention at this region. Nevertheless, the massive growth of algae can be viewed upon as a natural economic resource rather than a harmful impact. The present study was carried out to investigate the factors, favoring development of algal blooms and also to take advantage of the probable benefits afforded by this phenomenon. ····· 1036188695

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Both in the wild and in the clinical setting many bacterial species live within surface-attached, matrix-enclosed communities called biofilms, and today biofilms are considered to be an integral component in the life cycle of most microbial species. Additionally, biofilms are associated with the majority of human bacterial infections and in that context, bacteria are significantly more tolerant of antimicrobial agents. In spite of all their significance, this surface-associated life style has remained poorly understood, mostly due to the inherent complexities associated with their studies. This book is focused on dissecting the underlying biology of biofilm formation and some of the most fundamental biofilm-associated phenotypes in different bacterial species using a combination of systems-level experimental and computational approaches. The systematic frameworks presented in these studies, along with the acquired insights, should benefit the study of microbial biofilms formed by other species and set the stage for development of novel therapeutics against biofilm-associated infections. ····· 1036188631

The macromolecules are made up of primary subunits such as nucleotides, amino acids and sugars. It is the sequence in which the subunits are put together in the macromolecule, called the primary structure, that determines many of the properties that the macromolecule will have. Thus, the genetic code is determined by specific nucleotide base sequences in chromosomal DNA the amino acid sequence in a protein determines the properties and function of the protein and sequence of sugars in bacterial lipopolysaccharides determines unique cell wall properties for pathogens. The primary structure of a macromolecule will drive its function, and differences within the primary structure of biological macromolecules accounts for the immense diversity of life. A prokaryotic cell has five essential structural components: a nucleoid (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer, which may or may not be an inherent part of the wall. ····· 1036188560

In order to further characterise the CTL response to HTLV-1, an assay to quantify specific T cell effector functions was developed. I analysed degranulation (by CD107 mobilisation) and cytokine (IFN- and TNF- ) expression by both HTLV-1-specific CD8+ and CD4+ T cells in response to HTLV-1 Tax peptide. This study shows a trend of the frequency of degranulating CD8+ T cells to be higher in HAM/TSP patients, however at a given proviral load the rate of lysis of infected cells tend to be higher in ACs than in HAM/TSP patients. Interestingly, only the frequency of CTL degranulation correlated with the rate of killing of target cells, suggesting that CTL killing of target cells depends mainly on degranulation. ····· 1036188201

Various culture-based methods were also applied to quantify viable bacterial populations. The two DVC methods optimised in this study, successfully quantified `Living` (Viable culturable and VBNC) bacterial populations in natural waters. NADVCs and INTDVCs were consistently lower than total direct counts and also consistently higher than standard heterotrophic plate counts. Results obtained for cultured bacteria using both DVC methods were similar. However, for mixed bacterial populations, the counts were always higher with the INT method than with the NA method. Combining both DVC methods yielded a statistically significant increase in numbers of INT active cells compared with the INT method used alone. Substrate-enhanced INT method when combined with digitised image analysis, allowed for the identification of different bacterial morphological types and the quantification of the overall physiological states of individual bacterial cells in samples of raw domestic sewage. ····· 1036188000

Microwave sterilized media support better microbial growth. Both bacteria and yeast are able to achieve higher cell density at a faster growth rate in microwaved media. Microwave treatment is suitable for media of varying compositions. Better retention of nutrient quality in microwave treated growth media due to shorter heat exposure seems to be the major reason for better microbial growth in it. Microwave sterilization can prove an attractive alternative of conventional autoclaving, especially when media are needed for immediate use, and also when high biomass yield is of particular interest. Microwaved media may be of special value for growing recombinant organisms in high densities, so as to produce increased amount of the inserted gene product. ····· 1036187776· 1 · ::::: · 11 ·· 12 ·· 13 ·· 14 ·· 15 ·· 16 ·· 17 · ::::: · 24 ·
