ABSTRACT
Sacoglollis gabonensis is a plant used for the
preservation of palm wine in Southern Nigeria. Direct addition of the bark of
Sacoglottis gabonensis to fresh palm juice followed by microbial enumeration
every six hours showed that the bark of the plant inhibited bacterial growth
appreciably. The effect of various extracts of the bark on two bacterial
species isolated from palm wine (Leuconostoc mesenteroides and Lactobacillus
plantarum) was studied by using th© paper disc method. It was observed that
three of the five constituents of the bark showed inhibitory effect on the
bacterial. Ethanol, cold water, and hot water extracts of Sacogloltis
gabonensis (Nche) for antimicrobial activity of concentrations between 40mg/ml,
30mg/ml, 20mg/ml and 1 0mg/ml were used to prepare the disc for the susceptibility
testing using disc diffusion method. The sensitivity test of 30mg/ml and
40mglml of the ethanol extract showed higher zones of inhibition on the
isolates while the cold water of the same concentrations showed lesser zones of
inhibition. The microorganisms isolated from the palm wine includes;
Lactobacillus species, Bacillus species, Zymomonas species, Leuconostoc
species, Micrococcus species and Saccharomyces cerevisiae. Microflora analysis
of palm wine have shown that the initial inhabitants of palm wine are
predominantly Saccharomyces cerevisiae and to a small extent,
Schizosaccharomyces pombe and a Pichia specie. The addition of Sacoglollis
gabonensis to palm wine suppressed the growth of microorganisms in the palm
wine and therefore reducing the rate of palm wine spoilage.
