Relationship Between Ecological Parameters and Marine Bacteria From Mangrove Sediments of South East Coast of India.
Journal Title: PARIPEX-Indian Journal of Research - Year 2015, Vol 4, Issue 12
Abstract
The marine microbes might have better potential than their terrestrial counterparts. This is due to essential nutrients, amino acids, vitamins and minerals that are available in the marine biotopes for nurturing the organisms. Hence, in the present study, we investigated the lactobacilli from the rhizosphere soil of rare mangrove species from different biotopes of east coast of India to delineate the spatial and temporal variations of lactobacilli with regard to physico-chemical variables. Ecological studies on marine lactobacilli from mangrove sediment of east coast of India. Samples were drawn from four mangrove areas of east coast of India namely Sundarbans (West Bengal), Bhittarkanika (Orissa), Coringa (Andhra Pradesh) and Pichavaram (Tamil Nadu). The sampling was made from root soil (Rhizosphere soil) of six rare mangrove species from 12 sites. Fifteen physico-chemical parameters were analyzed in the sampling sites. The count lactobacilli were isolated from the soil samples and enumerated. The lactobacilli counts in these study areas varied significantly (p>0.05) with a range from 3.0×102 to 3.1 ×104 CFU g-1. The counts were recorded maximum with Hereteira fomes at Sundarbans and minimum in Rhizophora annamalayana at Pichavaram. The monthly variation of lactobacillli counts in rhizosphere soil of R. annamalayana, the only endemic species of India, varied from 3.0×102 to 9.9×102 CFU g-1. The maximum count was observed during the post monsoon month (Nov.) and the minimum in the summer month (May)
