Dispersion of small ceramic particles (Al2O3) with Azotobacter vinelandii
Article Abstract:
An investigation was conducted to determine if bacterial alginate from Azotobacter vinelandii could serve as an effective dispersant of small ceramic particles during the processing of clay. The results showed that fine alumina particles treated with A. vinelandii alginate were well dispersed. Furthermore, A. vinelandii could grow and produce alginate in alumina suspensions of up to 15%. These results imply that A. vinelandii may be used for the in situ processing of alumina particles for the production of high-quality ceramic clay.

Diversity and distribution of Frankia strains symbiotic with Ceanothus in California
Article Abstract:
A quantitative model was used to test the relative importance of geographic separation, host specificity, and environment in influencing the identity of Ceanothus Frankia symbionts as determined by ribosomal DNA sequence data. It was concluded that the identity of Frankia strains inhibiting Ceanothus nodules might involve interactions between host species specificity and geographic isolation.

In situ reproductive rate of freshwater Caulobacter spp
Article Abstract:
Research indicates that caulobacters undergo three reproductive cycles per day adding cell cycle marker stalk bands to the progeny. Submerged electron microscope grids in water were employed to measure caulobacters' in situ reproduction.
