High numbers of mycobacteria, including known pathogenic species such as Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium chelonae, were recovered from aerosols produced by pouring commercial potting soil products and potting soil samples provided by patients with pulmonary mycobacterial infections. The dominant mycobacteria in the soil samples corresponded to the dominant s...

Immature embryos of Cymbidium iridioides were successfully cultured on five different media with various supplements and maintained in three different light conditions. Within three week of culture, embryos formed nodular structures. Cultures under full light condition formed green protocorm-like bodies while, other light conditions failed to support optimum germination. Immature embryos of 10 ...

Anaerobically digested cattle biosolids are a by-product of cattle waste processing for pollution control and biogas production, yet this material has potential as an economical component of potting mixes used for sustainable nursery container production. As an animal waste, this material could have valuable fertilizer properties that could reduce the amount of supplemental fertilizer applied t...

Legionella longbeachae serogroup 1 and other Legionella spp. were isolated from 73% of 45 potting soils made in Australia by 13 manufacturers but were not detected in 19 potting soils made in Greece, Switzerland, and the United Kingdom examined between March 1989 and May 1990. Several Legionella species were isolated from a small number of samples of uncomposted pine sawdusts, but it is not kno...
