L.; Rucinsky, T. E.; Casida, L. E., Jr. Abstract: A study was conducted to obtain information concerning the fate of soil microorganisms during the procedures normally used in separating them from the soil in connection with various types of investigations. A silty clay ... NASA Center: NASA (non Center Specific) Publication Year: 1977 Added to NTRS: 2004-11-03 Accession Number: 78A12124; Document ID: 19780028215 New microbial growth factor Author(s): Bok, S. H.; Casida, L. E., Jr. Abstract: A screening procedure was used to isolate from soil a Penicillium sp., two bacterial isolates, and a Streptomyces sp. that produced a previously unknown microbial growth factor. This factor was an absolute growth requirement ...

L.; Casida, L. E., Jr. Abstract: A study to determine whether the firmness of microbial attachment that occurred for the overall bacterial population in natural unaltered soil could be duplicated for selected bacterial soil isolates introduced into ... NASA Center: NASA (non Center Specific) Publication Year: 1979 Added to NTRS: 2004-11-03 Accession Number: 79A51701; Document ID: 19790067688 Plating isolation of various catalase-negative microorganisms from soil Author(s): Labeda, D. P.; Hunt, C. M.; Casida, L. E., Jr. Abstract: A unique plating procedure was developed that allows isolation, but not enumeration, of representatives of the catalase-negative soil microflora. The numbers recovered, however, are low as compared to the numbers recovered ...

Author(s): Bae, h. C.; Casida, L. E., Jr. Abstract: Indigenous soil microorganisms were cultivated in their soil habitat with 50 moisture capacity at 30 C for two weeks. Changes in microorganism cells were studied by electron microscopy during incubation, with particular ...
