Huffman modulated interference contrast microscopy shows the outlines of empty sporangiospore cell walls as distinct from intact spores (Fig.

Of the various enzyme regimens used, we found a combination of chitinase and chitosanase worked best to remove the cell walls from Pilobolus sporangiospores. Because of the high proportion of lysed spores, we conclude that the mode of action is appropriate for the composition of the sporangiospore cell wall and speculate that the sporangiospore wall is comprised of, at least in large part, chitin and chitosan.

This study was undertaken to develop a technique that could provide sphaeroplasts from sporangiospores of the zygomycete, Pilobolus.

Sporangiospores of Pilobolus are contained within sporangia, making the sporangium the repository of a sample of cells that can be a source of DNA or protein.

Multiple enzyme treatments were attempted both with germinated and ungerminated sporangiospores. Chitinase and chitosanase were used individually at their optimum pH values and temperatures.

Germinated sporangiospores were produced by introducing 8-10 sporangia from a Petri dish lid into a solution of 50% SHM and 50% water and incubating the spores at 37[degrees]C for 24 h and then at room temperature for 24 h.

Ungerminated sporangiospores were used to produce sphaeroplasts by introducing 8-10 sporangia, collected from a Petri dish lid, to a 1.5 ml micro-centrifuge tube containing 100 [degrees]l of one of the enzyme solution regimens listed above.

DNA isolation and study.--A suspension of sporangiospores that had been lysed using the combined enzyme solution was washed twice with pH 5.5 phosphate buffer, centrifuged for 5 min at 3000 rpm, and added to tubes of a MoBio UltraClean[R] Soil DNA kit.

All five enzyme treatments of germinated sporangiospores resulted in production of sphaeroplasts.

Distribution of sporangiospores within the enzyme solution can be seen by preparing wet mount slides of this material.

Because Pilobolus sporangiospores are embedded in a common matrix, they tend to clump or stick together.

All of the enzyme treatments produced some sphaeroplasts from sporangiospores that had been disrupted.
