Phytopathogenic Fungi And Bacteria

Calia secundiflora (Ortega) Yakovlev (Fabaceae) is considered a medicinal plant in Mexico but has scarcely been used because of the toxicity of its quinolizidine alkaloids. Several quinolizidine alkaloids have shown bactericidal, nematicidal, and fungicidal activities. The purpose of this study was to identify the alkaloids in the seeds and evaluate the activity of the organic extract on several phytopathogenic fungi and bacteria. An in vitro bioassay was conducted with species of the following phytopathogenic fungi: Alternaria solani, Fusarium oxysporum and Monilia fructicola; and of the following bacteria Pseudomonas sp., Xanthomonas campestris and Erwinia carotovora. Cytisine, lupinine, anagyrine, sparteine, N-methylcytisine, 5,6-dehydrolupanine, and lupanine were identified by liquid chromatography-mass spectrometry in the extract of seeds; the most abundant compound of the extract was cytisine. It was observed that the crude extract of Calia secundiflora was moderately active on bacteria and more potent on phytopathogenic fungi. In contrast cytisine showed the opposite effects.

Laboratory Facilities

Two-stage techniques Tilley & Terry (1963) for the estimation of digestibility have 3 main disadvantages for use in developing countries with limited laboratory facilities. Carbon dioxide is needed to saturate the buffers; a centrifuge is necessary to separate residues from solubilised materials; and the methods uses pepsin as a proteolytic agent. The aim of the present study was to eliminate these three requirements for the faecal liquor method ( Omed et al., 1989), by replacing bicarbonate with phosphate buffer (Marten & Barnes, 1980), pepsin with biological washing liquid, and centrifugation with sedimentation.
