Soil Microbial Diversity

Each plant species is regarded to substantially influence and thus, select for specific rhizosphere microbial populations. This is considered in the exploitation of soil microbial diversity associated with important crops, which has been of interest in modern agricultural practices for sustainable productivity. This study used PCR-DGGE (polymerase chain reaction - denaturing gradient gel electrophoresis) in order to obtain an initial assessment of the bacterial and fungal communities associated in bulk soil and rhizospheres of different mungbean genotypes under natural field conditions. Integrated use of multivariate analysis and diversity index showed plant growth stage as the primary driver of community shifts in both microbial groups while rhizosphere effect was found to be less discrete in fungal communities. On the other hand, genotype effect was not discerned but not inferred to be absent due to possible lack of manifestations of differences among genotypes based on tolerance to drought under non-stressed environment, and due to detection limits of DGGE. Sequence analysis of prominent members further revealed that Bacillus and Arthrobacter species were dominant in bacterial communities whereas members of Ascomycota and Basidiomycota were common in fungal communities of mungbean. Overall, fungal communities had higher estimated diversity and composition heterogeneity, and were more dynamic under plant growth influence, rhizosphere effect and natural environmental conditions during mungbean growth in upland field. These primary evaluations are prerequisite to understanding the interactions between plant and rhizosphere microorganisms with the intention of employing their potential use for sustainable crop production.

Preliminary Study

Hypodematium crenatum (Forssk.) Kuhn and Anogramma leptophylla (L.) Link are threatened fern species from Western Ghats.  The present paper endorses the preliminary study on mycoflora associated with these ferns.  Eighteen fungal species have been isolated from rhizosphere and non-rhizosphere soils of selected ferns.  More diversity of fungi was observed in non-rhizosphere as compared to rhizosphere soils of both the ferns.  Aspergillus was found to be the most dominant genus among the population followed by Penicillium.  Higher percentage of fungal species is shown by H. crenatum, i.e., 44.5% in non-rhizosphere and 27.77% in rhizosphere; while a lower percentage of fungal species was found in A. leptophylla, i.e., 38.88% in non-rhizosphere and 16.66% in rhizosphere.  Number of colony forming units per gram soil was more in non-rhizosphere of A. leptophylla while it was less in non-rhizosphere of H. crenatum.  Inhibitory rhizosphere effect was exerted by A. leptophylla while H. crenatum has stimulatory effect on soil fungi.

As a result of the investigation of algogroups of coal-mining workings of mine administration “Zahidne” 44 species of algal from five departments (Cyanophyta, Chlorophyta, Bacillariophyta, Xanthophyta, Eustigmatophyta) were revealed. The coefficients of mesophility and xerophylity are calculated. The general spectrum of vital forms of algae species in spring period is represented by formula Ch14B5X3H2C2P1 (27), in summer period – Ch9P8B7X4H4C2V1CF1 (36). Key words: coal dump, soil algae, vital forms.
