R. Saraswathi, Dr.B. Rajani, M. Umadevi, C.H.L.P Shiva Kumari, Dr.P. Shivakumar Singh, T. Kumaraswamy and B. Mohan Abstract. An oxygenic phototrophic bacterium is the gram-negative bacteria that can use light as an energy source and they are anaerobic as they do not evolve oxygen during photosynthesis. Its very difficult to just start with identification of soil bacteria. The best you can do is try to find a good textbook/paper on isolation/identification of soil bacteria. You can start looking for papers about this and try to find specific media for soil bacteria. + try to find some bacteria (species for ex) that are known as "soil bacteria".

Isolation of bacteria can define as the technique of separating one speciesof bacteria from the mixed cultureof bacteria by different plating methods like pouring, spreading, streaking and serial dilution.
Significance and Impact of the Study: This study suggests that soil may be a common source for the isolation of lactic acid bacteria. Keywords: enrichment method, isolation, Japan, lactic acid bacteria, soil, Taiwan. INTRODUCTION Lactic acid bacteria (LAB) have played a long and important role in food technology. The LAB include a wide variety of
Normally, bacteria are isolated from one another using the streak plate technique, in which a sample of bacteria is spread out onto an agar plate in such a way that individual cells are separated from each other. Each cell multiplies to form a visible colony in which all the cells are the same strain (and essentially clones of each other).
Bacteria of the genus Azospirillum comprise 15 species to date, with A. brasilense the best studied species in the genus. Azospirillum are soil bacteria able to promote the growth of plants from 113 species spanning 35 botanical families. These non-pathogenic and beneficial bacteria are ubiquitous in soils and inhabit the roots of diverse plants.
Jun 01, 2013 · 2.1. Sample collection and isolation of chitinolytic bacteria. A total of 15 different soil samples were aseptically collected from different regions of Lucknow, India. The location of collected soil was rhizosphere of maize, wheat and rice, fish market and pond. For screening of chitinase producing bacteria, the agar medium amended with ...
The contaminated soil samples were enriched with the hydrocarbon degrading bacteria and as we isolated total 8 isolates from the oil contaminated soil. Four out of the 8 bacterial isolates were selected for further studies. These isolates were purified from the soil sample on the basis of colony morphology, texture, growth. The pure

  • Sep 08, 2020 · Remediation using microorganisms is recognized as one of the most effective, eco-friendly and cost effective method. The study is focused on isolating hydrocarbon degrading bacteria from oil contaminated soil, extracting and characterizing biosurfactant and to test their potential as an efficient bioremediation agent.
  • Sep 08, 2020 · Synthetic dyes from textile industries are common contaminants of water and possess serious environmental health hazards. The aim of the present study was to isolate and identify soil bacteria capable of degrading azo dyes. In the study, bacterial isolates capable of degrading azodye such as methyl red, were isolated from dye contaminated soil.
  • Phosphate solubilizing bacteria (PSB) have the potential to enhance phosphate-induced immobilization of metals to remediate contaminated soil. However, there is a limit on the amount of phosphate which can be added to the environment due to the issue of eutrophication.
  • General purposes:1- To make the students aware with the role of microbes in maintaining environment, existing microbial interactions and recycling of nut…
  • The goal of these studies was to determine how sorption by humic acids affected the bioavailability of polynuclear aromatic hydrocarbons (PAHs) to PAH-degrading microbes. Micellar solutions of humic acid were used as sorbents, and phenanthrene was used as a model PAH. Enrichments from PAH-contaminated soils established with nonsorbed phenanthrene yielded a total of 25 different isolates ...

Apr 14, 2013 · Lab 6 isolation of antibiotic producer from soil 1. • Subject objective: Each student should be able to• To isolate antibiotic-producing microorganisms (Bacillus, Penicillium and Actinomycetes colonies) from soil that may be antibiotic producers.•

Oct 01, 2014 · Some studies have shown that the application of K-solubilizing bacteria (KSB) and K bearing minerals increases the amount of available K in the soil and promotes plant uptake of K (Sheng et al., 2002, Sheng, 2005, Basak and Biswas, 2009, Abou-el-Seoud and Abdel-Megeed, 2012). Isolation and characterization of hydrogen-oxidizing bacteria induced following exposure of soil to hydrogen gas and their impact on plant growth Environ Microbiol . 2007 Feb;9(2):435-44. doi: 10.1111/j.1462-2920.2006.01155.x.
In this study, soil bacteria were isolated and characterized including its antimicrobial peptide. For this, soil samples were collected from agriculture lands. Soil samples were diluted and cultured in nutrient agar plates to obtain the isolated bacterial colonies. (1997). Isolation and some properties of methane-oxidizing bacteria from a subtropical paddy field. Soil Science and Plant Nutrition: Vol. 43, No. 3, pp. 735-740.

Results Isolation of acid‐producing bacteria. Fifty‐four strains of acid‐producing bacteria were isolated from 68 soil samples. Twenty‐five rod or short‐rod and 11 cocci bacteria were isolated from soil samples of Taiwan, while five rod or short‐rod and 13 cocci bacteria were isolated from soil samples of Japan.

Bacteria with the ability to grow on nitrogen-free media and with nitrogenase activity under aerobic or microaerobic conditions were isolated from sugarcane roots collected from four different agricultural locations in Granada (Spain). Isolates were Gram negative rods and were identified as Azotobacter chroococcum and Azospirillum brasilense. Our results suggest that Azotobacter isolates do ...
