dcterms:description
Cyanobacteria were immobilized on piece of hemp cloth. The amendment is intended for speeding recovery of microbiotic crusts in semi-arid and arid lands where such crusts have been destroyed by anthropogenic activities. Microcoleus vaginatus, Schizothrix calcicola, and Nostoc were used to create amendments. The amendment was found to retain its viability in storage for at least 18 months. M. vaginatus grew best in CT and Z8+ (plus vitamins) media with aeration and addition of KHCO3. A field test at Fort Irwin (NTC), Mojave Desert, California, showed significant increases in phototrophic biomass 6 and 12 months after inoculation, but the stimulus was not evident at 18 months. Four other field tests did not show significant gains. We suspect the failure of the field tests is due to a loss of cyanobacterial viability after inoculation but before favourable growth conditions. Cyanobacteria were possibly killed by UV irradiation or photo-oxidation in the hot desert environment. M. vaginatus is known Cyanobacteria were immobilized on piece of hemp cloth.
