In vitro regeneration of disease free enset [Ensete ventricosum (Welw) Cheesman] planting materials from bacterial wilt diseased plants using shoot tip culture
Enset is an important food crop produced in Ethiopia with great role in food security. The demand of the crop is increasing throughout the country. However, the production as a whole is decreasing due to devastation by enset bacterial wilt. The studies were conducted to develop the procedure for obtaining multiple disease free plantlets from infected enset plants. Shoot tip explants from infected suckers of three clones...

Screening of spontaneous castor bean accesses for genetic improvement programs
The objective of this work was to identify, through the use of multivariate analysis, the spontaneous accesses of castor bean that show promising characteristics for inclusion in genetic improvement programs of this culture in Brazil. The study was conducted at the Paulista State University, Jaboticabal Campus. The accesses of castor bean seeds obtained were identified as ACS-001-CRSP, ACS-001-JASP, ACS-001-MASP,...

Assessment of the genetic diversity of Kenyan coconut germplasm using simple sequence repeat (SSR) markers
Genetic diversity and relationship among 48 coconut individuals (Cocos nucifera L.) collections from the Coastal lowland of Kenya were analyzed using 15 simple sequence repeat (SSR) primer pairs. Diversity parameters were calculated using Popgene Software version 1.31. The gene diversity values ranged from 0.0408 (CAC68) to 0.4861 (CAC23) with a mean value of 0.2839. The polymorphic information content (PIC) values...

Evaluation of various pesticides-degrading pure bacterial cultures isolated from pesticide-contaminated soils in Ecuador
Due to the intensive use of pesticides within the greenhouse-rose production, remediation of polluted soils has become a hot topic for researchers in recent decades. Several bacterial strains having the ability to utilize various pesticides as a sole source of carbon and energy were isolated from pesticide-contaminated soils of Urcuquí, Ecuador. According to phenotypical, physiological, and biochemical...

Use of response surface methodology to optimize the drying conditions of a bioactive ingredient derived from the African opaque sorghum beer
The present work aims to optimize the heat drying conditions of a bioactive feed ingredient derived from the African opaque sorghum beer. The bioactive ingredient was dried at various temperatures 35 to 50°C and times 5 to 24 h. The effects of the drying conditions on the dry matter, water activity, pH, titratable acidity, bacteriocin, ethanol, lactic acid, yeasts, lactic acid bacteria contents and antimicrobial...

Enzymatic regulation of organic acid metabolism in an alkali-tolerant halophyte Chloris virgata during response to salt and alkali stresses
Chloris virgata, an alkali-tolerant halophyte, was chosen as the test material for our research. The seedlings of C. virgata were treated with varying salt and alkali stress. First, the composition and content of organic acids in shoots were analyzed and the results indicated that there was not only a significant increase in total organic acids, but there were also obvious changes in different components of organic...

Comparison of four nonlinear growth models for effective exploration of growth characteristics of turbot Scophthalmus maximus fish strain
This study was conducted to compare the effectiveness for non-linear growth models designated as Chapman-Richards, Gompertz, Logistic and von Bertalanffy for selection of fast-growing fish strain of turbot Scophthalmus maximus. These models were compared using the goodness of fit (the coefficient of determination (R2) and the mean square error (MSE)) and the Akaike information criterion (AIC) and the growth...

Genetic determinants of antifungal resistance in Candida species
In the previous decades, it has been an increase in cases of resistance to antifungal agents used in the prophylaxis and treatment of infections caused by Candida species. The emergence of resistance to drug classes, it is usually explained by genome alterations ranging from point mutations to gain or loss of whole chromosomes. Therefore, identify and understand into the molecular mechanisms that underlie resistance of...

Phylogenetic relationships of the genus Quercus L. (Fageceae) from three different sections
In this study, the genetic diversity of 6 oak species known as Quercus coccifera L., Q. robur L., Q. infectoria Oliver, Q. cerris L., Q. ithaburensis subsp. macrolepsis (Kotschy) Hedge and Yalt. and Q. trojana P.B. Webb in 18 populations was screened using the randomly amplified polymorphic DNA method (RAPD). 10 RAPD primers giving the best results produced 262 total loci. The highest and lowest band sizes...

Antioxidant assessment on promethazinr HCl decomposition using RP-HPLC assay method
The objective of this study was to investigate the effect of different sodium metabisulfite (SMBS) concentrations under a variety of ICH recommended test conditions. An attempt was made to test the feasibility of increasing shelf life when stored under different conditions. The promethazine hydrochloride (HCL) sample solutions used according to USP 24 and BP 1999 were prepared using different concentration of sodium...
