Principal criteria for selection of lactic acid bacteria for potential use as probiotics in foods
The use of lactic acid bacteria (LAB) in different food products has been driving the consumer market due to the potential probiotic action of these bacteria, which raises the foods to the status of functional foods. A selection of potential probiotic strains can be obtained from different food matrices and environments. However, these microorganisms must be confirmed as safe while retaining characteristics that make...

Microbial diversity analysis of subclinical mastitis in dairy cattle in Northeast China
The microbial diversity of a pooled milk sample (H) from healthy dairy cows in the Daqing region of Heilongjing Province in northeastern China was compared to that of four pooled milk samples (M1-M4) from dairy cows from the same area previously diagnosed with subclinical mastitis, based on the California mastitis test, using pyrosequencing of the metagenomic 16S ribosomal RNA genes. A total of 22 759 valid sequences...

Biochemical characteristics and microbial association of Isabgol (Plantago ovata Forks.) growing soils in Western Arid region of India
Isabgol (Plantago ovata Forks.) is one of the important cash crops in arid and semi-arid regions of India. The husk of Isabgol seeds are primarily used as laxative in medicinal preparations. The cultivation of Isabgol crop is very much dependent on soils and weather conditions as this crop is highly susceptible to many biotic and abiotic stress parameters. Soil microbial population is involved in many direct and...

Bacterial pathogens associated with hand-dug wells in Ibadan city, Nigeria
The supply of pipe borne water in Nigeria has over the years become grossly inadequate or totally non-existent. This has led many people to seek alternative sources of water from streams, springs and especially hand-dug wells. This study was carried out to investigate the bacteriological quality of water from hand–dug wells in Ibadan city. This was done by investigating bacterial indicator of water quality in...

Prevalence of Salmonella, Escherichia coli and coliforms on bell peppers from the field to the packing house process
The presence of Salmonella spp., Escherichia coli and coliforms from the field to the packing process of bell pepper was evaluated. A total of 900 samples including bell pepper, worker hands, surfaces, and hand-washing fruits were collected from 11-sampling sites of a farm. From the total samples analyzed, 2.6, 3.0, and 53.7% contained Salmonella spp., E. coli and coliforms, respectively. The highest percentage of...

Effects of plant growth promoting bacterial isolates from Kavango on the vegetative growth of Sorghum bicolor
Sorghum is an important cereal that is processed into a variety of foods and leisure beverages across the African continent. Low sorghum yields experienced in agriculture is a result of major production constraints such as soil nutrient deficiency and plant disease. It is important that the methods for crop production are of a sustainable nature as the chemical fertilizers in current use are detrimental to the natural...

Screening of microbial isolates for extracellular fructosyltransferase production
Fructooligosaccharides are gaining importance by leaps and bounce every day due to their low caloric value and accompanying health benefits for the consumer. Hence, newer potential sources for the fructosyltransferase (Ftase) enzyme are thoroughly scrutinized. The present work was carried out for preliminary and secondary screening of the microbial isolates for determination of the Ftase producing potential. Three...

Effect of Eichhornia crassipes on coliforms load in small water bodies within Lake Victoria basin, Kenya
The study investigates the effects of Eichhornia crassipes (water hyacinth) infestation based on coliform loads which are pollution indicator organisms. These dams have fish and the waters are commonly used for domestic purposes without any treatment hence it is necessary to check their status. Sampling was done on 25 small water bodies and from which water samples were taken for microbial determination. Membrane...

Screening of Amazon fungi for the production of hydrolytic enzymes
The use of fungi for the production of enzymes has been widely investigated, but there are few reports concerning the use of these organisms isolated from the Amazon Region for the production of hydrolytic enzymes. Considering the importance of hydrolases for different industrial applications, this work aimed to select Amazon fungi for the production of cellulase, protease, pectinase, amylase and xylanase. In order to...
