Soil type is the primary determinant of the composition of the total and active bacterial communities in arable soils

Article Abstract:

Research discusses the physical, chemical, and biological properties of soil in relation to the bacterial communities associated with a particulat type of soil. Results indicate that soil type influences the composition of the bacterial community in arable soils as in leguminous crops affecting the organic matter levels of soil therby causing changes in the bacterial population.

Responses of active bacterial and fungal communities in soils under winter wheat to different fertilizer and pesticide regimens

Article Abstract:

The composition of the active microbial (bacterial and fungal) soil community in an arable wheat field subjected to different management practices are examined at five times during a period of 1 year. Changes in the active microbial communities are investigated by denaturing gradient gel electrophoresis analysis of reverse transcription-PCR-amplified 16S and 18S rRNA.

Kraft pulp biobleaching and mediated oxidation of a nonphenolic substrate by laccase from Streptomyces cyaneus CECT 3335

Article Abstract:

Results show that laccase from Streptomyces cyaneus CECT 3335 oxidizes nonphenolic compounds and mediates biobleaching eucalyptus kraft pulp in the presence of chemical mediators. These properties render bacterial laccases suitable for the pulp and paper industry.
