Evaluation of genetic diversity in rice (Oryza sativa and Oryza glaberrima) germplasm from Liberia and Ghana using simple sequence repeat (SSR) markers

Rice is an important staple food crop that feeds over half of the global population and it has become the cereal that provides a major source of calories for the urban and rural poor in Africa. This research aimed to use simple sequence repeat (SSR) markers to evaluate the genetic diversity in rice (Oryza sativa and Oryza glaberrima) germplasm as breeding method. In the present study, 16 SSR markers were used across 48...

Xylose recovery from dilute-acid hydrolysis of oil palm (Elaeis guineensis) empty fruit bunches for xylitol production

The aim of this study was to evaluate the effect of different process conditions, such as the sulfuric acid concentration, contact time, solid:liquid ratio and particle size, on the xylose recovery and the formation of by-products from oil palm empty fruit bunch (OPEFB) with dilute-acid hydrolysis. Moreover, an adapted and non-adapted strain of the yeast Candida guilliermondii was used to obtain xylitol from the optimal...

Effect of encapsulated Pseudomonas putida strain PF1P on plant growth and its microbial ecosystem

Pseudomonas putida is a well-known plant growth promoting bacterium (PGPB) with the capacity to improve plant growth. The objective of this study was to assess the effect of P. putida towards plant growth and its interaction with its microbial ecosystem. P. putida strain PF1P was isolated from the rhizosphere of banana plant (Musa species). The isolated P. putida strain PF1P possess ability to secrete acetic acid (42.1...

Potentiality of lytic bacteriophages and their virolysins in lysing multi-drug resistant Salmonella typhi

Bacteriophage virolysins or lytic enzymes are bacterial peptidoglycan hydrolases responsible for lysing bacterial cells. Consequently, they are used as enzybiotics alongside with bacteriophage therapy to remedy multi-drug resistant Salmonella typhi. The objective of this study was to evaluate the potentiality of lytic bacteriophages and their virolysins in curing multi-drug resistant S. typhi. S. typhi was isolated and...
