PRACTICAL 1
TITLE: ISOLATION OF MICROORGANISMS FROM SOIL
SIGNATURE:
, OBJECTIVE: TO ISOLATE MICROORGANISMS FROM SOIL
Principle:
Different microorganisms form associates with plants for their nutritional
requirements. Soil, therefore, forms a suitable source for isolating these
microorganisms. Depending on the growth media used, these microorganisms can
be successfully isolated and their morphological characteristics established.
INTRODUCTION:
Ubiquitous microorganisms are in every part of the biosphere, including soil, hot
springs, and inside rocks at least nineteen kilometers deep underground, etc.,
Microorganisms present in soil play an important role in maintaining the
biological balance in the life of our planet. All soils contain varying amounts of
bacteria, fungi, and viruses depending on soil conditions. The permitted degree of
acidity and the types of residue added also determine the relative abundance of
microbes. The soil fertility and the accumulation of organic matter within a short
time depending on the bacterial amount (Kummerer, 2004).
The products and the byproducts of microorganisms in soil are beneficial to
increase the nutrient contents in soil, plant growth and also play an important
role in nutritional chains. Microorganisms in the soil also play a major role in
changing the nutrients into a form that can be used. Microorganisms in soil play a
crucial role in biogeochemical cycles and in the sustainable development of the
biosphere (Nakuleshwar et al,2013). Microorganisms present in soil produce and
consume two or three major naturally occurring greenhouse gases.
Common bacterial genera isolated from soil include Bacillus,
Arthrobacter, Pseudomonas, Agrobacterium, Alcaligenes,
Clostridium, Flavobacterium, Corynebacterium, Micrococcus,
Xanthomonas, and Mycobacterium.
