Based on 16S rRNA sequence comparison, we have designed a 20-mer
oligonucleotide that targets a region specific to the species Lactobacillus manihotivorans recently isolated from sour
cassava fermentation. The probe recognized the rRNA obtained from all the L. manihotivorans strains tested but did not recognize
56 strains of microorganisms from culture collections or directly isolated from sour cassava, including 29 species of lactic acid bacteria. This probe was then successfully used in quantitative RNA
blots and demonstrated the importance of L. manihotivorans in the fermentation of sour cassava starch, which could represent up to
20% of total lactic acid bacteria.
