Study of the effectiveness of essential oils of Mentha aquatica L. and Pimpinella anisum L. in the microbiological stabilization of pasteurized plant extract of Cyperus esculentus L. in Mali

This study evaluates the antimicrobial properties of essential oils of Mentha aquatica and Pimpinella anisum in the stabilization of pasteurized plant extract of Cyperus esculentus in Mali. The extraction of essential oils was carried out by steam distillation of the aerial organs of M. aquatica harvested in Bamako and the seeds of P. anisum harvested at Diré in Timbuktu Region. Aging tests were carried out by...

Optimization of regeneration protocol and prospecting spectinomycin resistance in barley (Hordeum vulgare L.) cv Haider-93

Immature zygotic embryos from spring barley cv. Haider-93 were used to induce somatic embryogenesis. The type of the explant, the level of 2,4-dichlorophenoxyacetic acid (2,4-D) and handling of calli during subculture are critical factors to obtain maximum number of regenerants. Different concentrations of 2,4-D (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mg/L) and Kinetin (0.5, 1.0, 1.5, 2.0 mg/L) were used for callus induction...

Molecular characterization of probiotic Enterococcus hirae from fermenting acalypha wilkesiana (Irish Petticoat) and Talinum triangulare (Water Leaf) medicinal plants

Research on lactic acid bacteria (LAB) continues to be relevant in the development of nutraceuticals. In this study, edible medicinal Talinum triangulare and Acalypha wilkesiana were collected and subjected to spontaneous fermentation for 24 h. Samples were collected at 6 h intervals for determination of pH and microbial analysis. Determination of LAB percentage frequency occurrence, probiotic properties, and safety...
