Partial characterization of bacteriocin-like substance produced by probiotic Lactobacillus plantarum F12 isolated from Algerian children faeces
The strain, Lactobacillus plantarum F12 with probiotic traits was isolated from Algerian healthy children faeces and identified by 16S rDNA sequencing. In this study, the antimicrobial activity and physicochemical properties of bacteriocin-like substance (BLS) produced by this strain were determined. Also, the bacteriocinogenic genes of plantaricin A, plantaricin J and plantaricin K were screened in this strain. The BLS...
Effectiveness assessment of mouthwashes formulated from the essential oils of some beninese medicinal plants against oral germs
Faced with the increasing growth of microorganism’s resistance to conventional antibiotics, the search of new bioactive molecules having pharmaceutical interest is more than ever committed. This study aimed to evaluate in vitro the effectiveness of seven mouthwashes formulated from essential oils of Ocimum gratissimum, Ocimum basilicum, Cymbopogon citratus, Clausena anisata, Lippia multifora, Eugenia caryophyllata...
Characterization of arbuscular mycorrhizal fungi in apple (Malus domestica Borkh) growing area in Kashmir Himalaya (India): A case study of Bandipora district
Rhizosphere soil samples and root pieces of 3 year old apple trees (var. Red delicious) were collected from 10 villages of district Bandipora of Kashmir Himalaya. Samples were processed for isolation of arbuscular mycorrhizal spores and their identification. On the basis of various morphological characters such as spore shape, colour, size, hyphal colour and with the help of International Collection of...
Storage behaviour and functionality of a heat stabilized starter derived from an African opaque sorghum beer
Tchoukoutou is a traditional sorghum opaque beer produced and consumed in Benin. It is obtained from an uncontrolled fermentation of sorghum wort using a traditional starter called “kpete-kpete”. The present study assessed the effects of storage duration on the physicochemical and microbiological characteristics as well as on the functional properties of the heat stabilized starter produced from...
Selection of anti-wetting agents and photoprotectants compatible with a soybean weed control bioagent
Adjuvants incorporation at formulations can positively influence the performance of bioagent control, contributing to preservation of the inoculum until being used. Adjuvants should not be toxic to pathogen and tests that evaluate the sensitivity of biologic products are essential. The aim of this study was to analyze the compatibility of the anti-wetting agents microcrystalline cellulose, anhydrous sodium carbonate,...
Identification and tracking of microorganisms from the biofilms of container walls used for water storage: Case of rural communities in Burkina Faso
Safe drinking water is an important necessity for humans. In rural communities of Burkina Faso, many households use local containers for storing drinking water. During water storage, some microorganisms get attached to the surface walls of the containers to form a biofilm which can deteriorate drinking water quality over time. This study aimed at evaluating the attachment of indicator microorganisms to containers walls...
