The purpose of this
study was to investigate the diversity of cultivable nitrogen fixing, phosphate
solubilising and total bacteria originated from 580 rhizospheric acidic
soils samples of tea plants grown at 62
locations. Based on FAME profiles of
over 1428 rhizoplane bacteria, 63 bacterial genera were identified with a similarity index > 0.3, but 56.4% of
the identified isolates belonged to six genera: Bacillus (37.02%), Pseudomonas (12.67%), Stenotrophomonas (5.71%), Paenibacillus (6.58%), Arthrobacter (4.35%) and Brevibacillus (3.98%). Most of the total,
N₂-fixing and P-solubilizing
bacteria isolated were Gram positive (59.9, 58.8 and 56.3%) and Gram negative
constituted only 40.1, 41.2 and 43.7%. Among different groups, Firmicutes, Gammaproteobacteria and Actinobacteria
comprised the largest groups contributing to about 50.3 and 46.6%, 30.8 and
32.5%, and 8.3 and 9.6% of the total N₂-fixing and P-solubilizing isolates, respectively. B. cereus, P. fluorescens, B. megaterium, S. maltophilia,
P. putida, B. licheniformis, B.
pumilus, B. subtilis and P. polymyxa were the most frequent N₂-fixing
and P-solubilizing species in the acidic tea rhizosohere soils. In these
studies were evaluated to represent the dominant culturable diversity of
diazotrophs and phosphobacteria, and thus potentially beneficial to the growth
and survival of tea plants in that specific acidic ecosystem of eastern Black
Sea region.
