A Malian native Azospirillum sp. Az6-based biofertilizer improves growth and yield of both rice (Oryza sativa L.) and maize (Zea mays L.)

The objective of this study was to improve rice and maize yields using native Azospirillum-based biofertilizer. To reach this objective, samples of rhizosphere soil, non-rhizosphere soil and roots of maize plants were collected from the particular locations of Samanko and Bamako of the south Mali. Thirty-three different colonies of bacteria were isolated from the different samples. Based on their better growth in...

Isolation and characterization of haloalkaliphilic bacteria from the hot springs of Lake Magadi

The Magadi Lake located in the Southern Rift Valley in Kenya is a hypersaline and alkaline lake. The lake’s pH ranges from pH 9 to 11 whereas the salinity can reach saturation during the dry Season. Little studies have previously been done on Lake Magadi as compared to other soda lakes from Kenya. This study concentrated on isolating and characterizing haloalkaliphilic bacteria found in the hot springs of Lake...

Cytological changes in Solanum lycopersicum seedlings in response to some rhizopheric fungi

Some rhizospheric fungi of Solanum lycopersicum were isolated from Cairo governorate and identified in Taxonomy Department, Ain-Shams University, Cairo City, Egypt. These isolated fungi were cultivated on soil extract medium enriched with 2% (w/v) glucose and 5% (w/v) yeast extract. The cytological effects of the metabolites of these fungi on the seeds of S. lycopersicum were examined after three different intervals (6,...

Molecular characterization, biofilm production and sensitivity to the natural extract of Staphylococcus spp. from subclinical mastitis in goats

Mastitis is one of the most important diseases in dairy milk systems. Molecular studies of the principal agents that are involved, as well as tests of bacterial sensitivity to plant extracts, are currently the most common forms of research related to this disease. The aim of the present study was to molecularly characterize isolates from cases of subclinical mastitis and to investigate the production of biofilm...

Comparison between wet and semi-dry anaerobic biogas diester under thermophilic and mesophilic conditions: Methane productivity and analysis of microbiota

The current practice of using stanchion breeding cow houses results in a semi-dry manure that ideally should be used as the substrate for the anaerobic fermentation. The conventional liquid-slurry biogas fermentation is disadvantageous with high running costs due to requirement such as water addition and running efficiency, among others. This study aimed to establish a high-speed semi-dry methane fermentation system for...

Epidemiology of pathogenic microorganisms, basic diseases and clinical biomarker analysis in patients with bloodstream infections from a 3A General Hospital in Lanzhou of China

The aim of this study is to investigate the burden of basic diseases, the epidemiology of pathogenic microbes in patients with bloodstream infections and their clinical biomarkers. Data on bloodstream infections from 2012 to 2018 were obtained from a 3A General Hospital in Lanzhou of China. 1990 patients with bloodstream infections participated in the study; their basic diseases, pathogenic microorganisms and...

Suitability of bacterial fermentation and foil packaging of condiment from African mesquite (Prosopis africana) seeds for nutritional retention and commercialization

The process for bacterial fermentation and foil packaging of condiment (‘Okpeye’) from African mesquite seeds was described and its nutritional enrichment and packaging improvement for commercialization were verified. The seeds (1 Kg) were cleaned, washed and boiled in autoclave at 121°C for 2 h, cooled, drained, de-hulled and divided into two portions of 300 g each. One portion was placed in sterile...

Isolation and characterization of rhizospheric microorganisms from bacterial wilt endemic areas in Kenya

Ralstonia solanacearum is a soil-borne bacterium causing bacterial wilt, particularly in Solanaceae crops, including tomatoes. Due to pathogen’s wide host plant range, pesticide resistance, and ability to overcome cultivars utilized for innate resistance, not even a single measure is effective against the pathogen. Screening the rhizosphere of bacterial wilt tolerant tomato plants from Bomet, Kiambu, Kajiado and...

Bridging technique failure through low-tech improvisation: A case study of food microbiology

Modern technology for food safety studies includes standardized protocols and equipment. However, appropriate technology needs to step in to bridge technology dys- or malfunctioning. We examined different low-tech methods for extraction of bacteria from fresh vegetables. Standard equipment including stomacher and filter bags were compared to extraction using bread stick and alternative filter material (nylon stocking,...

Antimicrobial activity of coconut water, oil and palm kernel oils extracted from coconut and palm kernel on some plasmid-mediated multi-drug resistant organisms associated with food spoilage

This study is aimed at evaluating the antibacterial and anticandidal activity of coconut oil, fermented and unfermented coconut water and palm kernel oil (PKO) on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Corynebacterium sp. and Candida albicans. The coconut water was fermented with Saccharomyces cerevisiae and the pH, sugar and alcohol contents were determined before and after fermentation. The...
