swan neck flask caught the bacteria and the broth had no growth. 4) Who established microorganisms as the causative agent of infectious disease? How did he do this? What was the result of this body of work? * Robert Koch * Studied Bacillus anthracis * Took diseased mouse with anthrax and infected healthy mouse. This healthy mouse got sick. He then removed the spleens from the sick mice and isolated the anthrax spore. He injected that into healthy mice and they got sick.

MICROBIAL NUTRITION Nutrition which is also called as nourishment or aliment is a provision to the cells and organisms with the materials necessary to support life. Here it deals with the nutrition in microorganism which is called as microbial nutrition. Nutrients may be divided into three general‚ often overlapping categories: Those that supply energy‚ those that supply carbon‚ and those that supply any and everything else. In this lecture we will consider nutrition from the point

avian Mycoplasma was caused by several pathogenic Mycoplasmas of which Mycoplasma gallisepticum which was considered the most important pathogenic one so‚ the office international des Epizootic (OIE) had designated the disease caused by M. gallisepticum as notifiable. M. gallisepticum occurred world-wide and was particularly important in chicken and turkeys as a cause of respiratory disease and decrease production.

Result and discussion 2.1 Physicochemical properties The formations of BPM I-III were confirmed by FT-IR‚ powder XRD and SEM studies. 2.1.1 Fourier transform infrared spectroscopy FT-IR spectra of BPM I-BPM III (Fig. 1a-1c) exhibited characteristic absorption bands of CTS ranges from 1637-1639 cm−1 which are attributed to amide I bands (C=O stretching mode along with an N–H deformation mode). Broad bands from 1130-978 cm−1‚ 1131-975 cm−1 and 1131-971 cm−1 were observed for phosphate stretching

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Vol 454j14 August 2008jdoi:10.1038/nature07190 REVIEWS Genomics of cellulosic biofuels Edward M. Rubin1‚2 The development of alternatives to fossil fuels as an energy source is an urgent global priority. Cellulosic biomass has the potential to contribute to meeting the demand for liquid fuel‚ but land-use requirements and process inefficiencies represent hurdles for large-scale deployment of biomass-to-biofuel technologies. Genomic information gathered from across the biosphere‚ including potential

a section (lobe) of a lung. Bronchial pneumonia (or bronchopneumonia) affects patches throughout both lungs. Pneumonia is not a single disease. It can have over 30 different causes. There are five main causes of pneumonia: bacterial‚ viruses‚ mycoplasmas‚ other infectious agents‚ such as fungi – including pneumocystis and various chemicals. Bacterial pneumonia can attack anyone from infants through the very old. Alcoholics‚ the debilitated‚ post-operative patients‚ people with respiratory diseases
