[Spore rec-assay by dry sheet medium culture plate for bacterial counts].

A simple and rapid method for spore rec-assay by utilizing dry sheet medium culture (Compactdry TC, CTC) for determining numbers of bacteria, instead of the spore agar plate, was developed. One mL of spore suspension (2 x 10(6)/mL) of Bacillus subtilis strain M45 Rec- or H17 Rec+ was inoculated in the center of the CTC plate. In the case of metabolic activation, 1 mL of mixed solution (spore su...

Specific and sensitive plate assay for bacterial lipases.

A plate assay to detect bacterial lipase (EC 3.1.1.3) in a medium containing trioleoylglycerol and the fluorescent dye rhodamine B is presented. Substrate hydrolysis causes the formation of orange fluorescent halos around bacterial colonies visible upon UV irradiation. The logarithm of lipase activity from cell-free culture supernatants is linearly correlated with the diameter of halos, thereby...

Validation of drop plate technique for bacterial enumeration by parametric and nonparametric tests

Drop plate technique has a priority and preference compared with the spread plate procedure, because of less time, quantity of media, effort requirement, little incubator space, and less labor intensive. The objective of this research was to compare the accuracy and fidelity of drop plate method vs. spread plate method by parametric and nonparametric statistical tests. For bacterial enumeration...

Bacterial culture preservation in frozen and dry-film methylcellulose.

Forty-seven of 61 bacterial cultures, including strains of Pseudomonas, Xanthomonas, Erwinia, Agrobacterium, Corynebacterium, Serratia, Klebsiella, and Escherichia, remained viable after storage in frozen methylcellulose or in dried methylcellulose for up to 38 months. Pathogenicity remained intact for those strains tested. Bacteria were grown on a solid medium and then removed and placed in 1....
