Biodiversity. How Pharmaceutical companies are extracting precious plants and knowledge from poor countries and indigenous tribes strictly for profit
Plants as sources of healing substances are evident in the fact that many of them were planted at home within the close reach of the homeowners for use in the event of ailment. Many medicinal plants were thus planted in farm gardens so that they could be used for treating fast illnesses whenever they occurred even without the intervention of other remedies. Physicians, midwives and herbalists in the 1800s were specifically trained in the use of medicinal plants to solve various medicinal

By lowering the pH, the conditions become unfavourable for harmful bacteria, making this process effective. This process also finds use in producing sauerkraut. This process utilizes genus Leuconostoc (Dworkin, 2006, 541).In lactic acid fermentation, the product will be dependent on the strain of microbe used. The strain of microbe that is used for fermentation will influence the stereo-specificity of the product. The organism to be used in the fermentation process is also reliant on the type

Bacterial plant pathogens in soil
In agriculture, one of the factors that can be tweaked to improve sustainability of a practice is the soil management. Soil is a vital tool of agriculture, as it houses many factors that affect plant growth such as organic material, water and soil bacteria.Bacteria are everywhere. We might not notice them because we cannot see them, but they are important to us, most noticeably because some of them cause harm to humans and animals. However, they perform different functions that are vital to our

Bioremediation of toxic heavy metals does it work in practice
The digestive system of a worm is capable of heavy metal ions detaching from aggregates between these ions and humic substances in the waste as it rots (Pattnaik and Reddy, 2012). In the process of enzymes activation the assimilation of metal ions is mediated by worms.In another research conducted by Turpeinen (2002) it is claimed that different bacteria, fungi, algae and actinomycetes are able to consume large amount of heavy metals. The researcher underlines a special ability of Chlorella,

Bioinformatics and molecular modelling
The activities of all lipases often rely on the catalytic triad that is usually fromed by the Asp, Ser, and His residues. In the sequence of the amino acid especially involving α/β hydrolases, these three residues often follow the user-Asp-His order. Additionally, lipases often share the consensus sequence defined by the Gly-Xaa-Ser-Xaa-Gly where X may be a residue of an amino acid (Bos and Laxminarayan, 2011; p.The three dimensional structure of any protein molecule often provides valuable

The parasporal bodies contain insecticidal toxins such as the cry proteins. In the view of Sparks, Michaels and Daniels (2013), the gypsy moths consume the proteins which become activated after they are injected into their bodies. The proteins then become bound to specific plasma membrane receptors on the midgut section of the insect pests; epithelium. They sip into the cell membrane and determine the formation of amphillic pores. Sparks, Michaels and Daniels (2013) summarize that an abnormal

Consequently, in testing for the synergism between the captopril and artesunate in vivo, the IC50 values for both drugs were determined for single doses. The effect of this was that a substance that was not affected by the drug, its obtained vascular area was to be 50% of the negative control. If lower than 50%, then the substances acted antagonistically, while if higher than 50%, then the substances acted synergistically. In this case, the IC50 single dose treatments in concentrations for both
