Application of biotechnology for the domestication of Dacryodes edulis (G. Don) H. J. Lam in Cameroon: A review
Cultivation of Dacryodes edulis (G. Don) H. J. Lam commonly known as safou to improve the livelihood of the local population has been growing rapidly in the range of occurrence of safou and recent emergence of the market chain introduced by the World Agroforestry Center (ICRAF) experts has stimulated this further. Domestication through conventional genetic improvement (breeding) of safou has relied on phenotype...

Growth performance and nutrient utilization of Clarias gariepinus fed with different dietary levels of processed cassava leaves
The growth performance of Clarias gariepinus fed with different dietary levels of processed cassava leaves and their nutrient utilized were studied for a period of 24 weeks. One hundred and forty four experimental Catfish (Clarias gariepinus) with 0.75±0.20 g mean weight and 3.9±0.31 cm mean total length were collected from Aqua-fish Consult, Awka, Anambra State, Nigeria. Eighteen rectangular plastic tanks...

Influence of aluminum on root growth and of anatomy Stenocalyx dysentericus (DC.) O. Berg
This study aimed to evaluate the effect of aluminum (Al) on root growth and root anatomical structure of Stenocalyx dysentericus seedlings. Newly emerged plants were grown in simple solution composed of 0.1 µM of CaCl2.2H2O and five Al concentrations of 0, 150, 300, 600, and 1200 μM for 37 days in a hydroponic system. Subsequently, the seedlings were evaluated for root growth, relative root elongation, and...

Physicochemical analysis of cellulose from microalgae Nannochloropsis gaditana
Nannochloropsis gaditana is a microalgae belonging to the class of Eustigmatophyceae. This particular microalga is the most studied species. For its richness in lipids, it is used for the biodiesel production. The aim of this work is to advance another important metabolite which is cellulose. This represents 25% of the dry weight of the N. gaditana. A low concentration of NaOH (2%) and sodium hypochlorite (6%) allowed...

Effect of different microencapsulation materials on stability of Lactobacillus plantarum DSM 20174
The aim of this work was to investigate the effect of different microencapsulation materials on the stability of probiotic bacterium (Lactobacillus plantarum DSM 20174). Microencapsulation methods with alginates were carried out using sodium chloride, canola oil, olive oil, and chitosan. The recorded data showed that the encapsulated probiotic bacterium was more stable compared with free cells. Olive oil capsules...

Potential biosurfactant producing endophytic and epiphytic fungi, isolated from macrophytes in the Negro River in Manaus, Amazonas, Brazil
Endophytic and epiphytic fungi isolated from Eichhornia crassipes (Mart.) Solms and Cyperus ligularis L., macrophytes collected from oil-contaminated waters, were studied to assess their potential for producing biosurfactants; the most promising ones were identified by means of the rDNA region sequencing. In the selection, in the hydrocarbonate biodegradation activity, 2.6-indophenol (DCPIP) in oil-added Bushnell-Haas...

Foot-and-mouth disease (FMD) prevalence and exposure factors associated with seropositivity of cattle in north-central, Nigeria
This study was designed to determine the seroprevalence and risk factors associated with foot-and-mouth disease (FMD) seropositivity in north central, Nigeria. A cross-sectional study was undertaken from February 2013 to April 2014 using 1206 sera from 150 herds collected by multi-stage and random sampling methods. Pre-tested questionnaire were also administered to participating farmers to collect information on the...

GhNAC18, a novel cotton (Gossypium hirsutum L.) NAC gene, is involved in leaf senescence and diverse stress responses
GhNAC18 is a novel NAC gene that was isolated from cotton (Gossypium hirsutum L.). The full-length cDNA was 1511 bp including an open reading frame of 1260 bp in length and encodes a protein of 419 amino acids. With qRT-PCR analysis, GhNAC18 was downregulated during natural and dark-induced senescence, implicating this gene as anti-aging gene in cotton. Analysis of its promoter revealed a group of putative cis-acting...

Fatty acids and amino acids contents in Scomber scombrus fillets from the South East of Tunisia
Proximate composition, fats and amino acids of Atlantic Mackerel fillets (Scomber scombrus) from the South East of Tunisia in different seasons, were analyzed in order to assess nutritive characteristics of this species. Samples were collected monthly from Zarzis fishing port located in the South-East of Tunisia. Total fats and protein contents varied significantly (P<0.05) according to the season. The highest values...

Chitosan from shrimp shell (Crangon crangon) and fish scales (Labeorohita): Extraction and characterization
Chitosan is a naturally available biopolymer. It has been prepared by alkaline N-deacetylation process of shrimp (Crangon crangon) chitin and fish (Labeorohita) chitin. The physico-chemical properties such as the degree of deacetylation (DD), solubility, water binding capacity, fat binding capacity and chitosan yield have indicated that shrimp shell and fish scale waste are good sources of chitosan. The deacetylation...
