Modified from Oosterhuis, Stages of Growth The developmental phases for cotton can be divided into five main growth stages:
Antibiotic is one of the most important commercially exploited secondary metabolites produced by bacteria, fungi and Streptomyces and employed in a wide range. Most of the antibiotics used today are from the microbes. Bacteria are easy to isolate, culture, maintain and to improve their strain.
Bacillus species being the predominant soil bacteria because of their resistant endospore formation and production of vital antibiotic like polymyxin, bacitracin etc. In the present research study, screening of bacteria, fungi and Streptomyces with potential antibiotic activity was carried out.
Among the microbes isolated and identified, Bacillus subtilis, Penicillium chrysogenum and Streptomyces spwere selected on the basis of their anti-bacterial activity.
It was observed that Penicillium chrysogenum metabolites showed maximum antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumonia with a zone of inhibition of 17mm, 11mm, Bacillus subtilis metabolites showed activity against Staphylococcus aureus and Pseudomonas aeruginosa measured as zone of inhibition of Antibiotics, in one form or another, have been in use for centuries.
Although a wide taxonomic range of microbes have the ability to produce antibiotics.
The New Demography of American Motherhood. By Gretchen Livingston and D’Vera Cohn. Executive Summary. This report examines the changing demographic characteristics of U.S. mothers by comparing women who gave birth in with those who gave birth in Huck's interaction with Mary Jane also highlights an emerging aspect of his growth, namely an interest in women. In The Adventures of Tom Sawyer, Huck viewed girls as nothing more than an annoyance and did not believe they were to be taken seriously. Moral Growth in Huck Finn Essay Sample. In the classic American literature novel “The Adventures of Huckleberry Finn”, by Mark Twain, the main character Huck experiences various occasions of moral growth.
With advances in organic chemistry many antibiotics are now also obtained by chemical synthesis, such as the sulfa drugs. Drugs used in the chemotherapy of infectious diseases are classified into two groups.
Drugs that have been synthesized by chemical procedures in the laboratory are called synthetic drugs while those produced by bacteria and fungi are called antibiotics 2. The antibiotics are widely distributed in the nature, where they play an important role in regulating the microbial population of soil, water, sewage, and compost.
Of the several hundred naturally produced antibiotics that have been purified, only a few have been sufficiently non-toxic to be of use in medical practice. Those that are currently of greatest use have derived from a relatively small group of microorganisms belonging to the genera Penicillium, Streptomyces, Cephalosporium, Micomonospora and Bacillus 3.
Antibiotics are low molecular-weight non-protein molecules produced as secondary metabolites, mainly by microorganisms that live in the soil.
Therefore, many species such as Streptomyces, Bacillus and Penicillium have been studied continuously for their ability to produce antibiotics 4. Currently, the target is to produce antibiotics such as polymyxin and bacitracin from Bacillus 5, 6.
The apparent increase of the occurrence of antibiotic resistance among bacteria during the past years and its possible implication in public health has led to an intensified surveillance of bacterial resistance in many countries.
Treatment of infectious diseases caused by pathogenic bacterial and fungal strains was one of the most traditional problems in the clinical field 9, This necessity encouraged the investigators to synthesize novel and more potent inhibitory compounds like azoles and quinolones derivatives 11, 12 to fight them.Modified from Oosterhuis, Stages of Growth.
The developmental phases for cotton can be divided into five main growth stages: (1) germination and emergence (2) seedling establishment (3) leaf area and canopy development (4) flowering and boll development and (5) maturation (Fig.
