A lactic acid bacterium with potential application in cassava fermentation IRD
Giraud, Eric; Brauman, Alain; Kéléke, S.; Gosselin, Laurent; Raimbault, Maurice.
An amylolytic lactic acid bacterium, identified as #Lactobacillus plantarum$, was isolated from cassava roots (#Manihot esculenta$ var. Ngansa) during retting. Cultured on starch, the strain displayed a growth rate of 0.43 per hour, a biomass yield of 0.19 g/g, and a lactate yield of 0.81 g/g. The growth kinetics were similar on starch and glucose. Enough enzyme was synthesized, and starch hydrolysis was not a limiting factor for growth. The synthesized amylolytic enzyme was purified by fractionated precipitation with ammonium sulfate and by anion exchange chromatography. It was identified as an alpha-amylase with an optimal pH of 5.5 and an optimal temperature of 65°C. The use of such a strain as a cassava fermentation starter for gari production had the...

Diversity of lactic acid bacteria associated with fish and the fish farm environment, established by amplified rRNA gene restriction analysis Inra
Michel, C.; Pelletier, C.; Boussaha, M.; Douet, D.G.; Lautraite, A.; Tailliez, P..
Lactic acid bacteria have become a major source of concern for aquaculture in recent decades. In addition to true pathogenic species of worldwide significance, such as Streptococcus iniae and Lactococcus garvieae, several species have been reported to produce occasional fish mortalities in limited geographic areas, and many unidentifiable or ill-defined isolates are regularly isolated from fish or fish products. To clarify the nature and prevalence of different fish-associated bacteria belonging to the lactic acid bacterium group, a collection of 57 isolates of different origins was studied and compared with a set of 22 type strains, using amplified rRNA gene restriction analysis (ARDRA). Twelve distinct clusters were delineated on the basis of ARDRA...

Screening of microorganisms for biodegradation of poly(lactic acid) and lactic acid-containing polymers IRD
Torres, A.; Li, S.M.; Roussos, Sevastianos; Vert, M..
The ability of some microorganisms to use lactic acid stereocopolymers and copolymers with glycolic acid as sole carbon and energy sources was studied under controlled or natural conditions. First, 14 filamentous fungal strains were tested in liquid cultures, adopting total lactic acid consumption, nitrogen source exhaustion, and maximal biomass production as selection criteria. Two strains of #Fusarium moniliforme$ and one strain of #Penicillium roqueforti$ were able to totally assimilate DL-lactic acid, partially soluble racemic oligomers (Mw = 1,000) and the nitrogen source. Only one strain of #F. moniliforme$ was able to grow on a poly(lactic acid) - glycolic acid copolymer (Mw = 150,000) after 2 months of incubation at 28°C on synthetic agar medium....
