A protocol for Agrobacterium-mediated transformation of Kalanchoë blossfeldiana with a flavonoid 3',5' hydroxylase (F3'5'H) gene

In the present investigation, explants from Kalanchoë blossfeldiana were used for gene transformation. The young leaves were inoculated with Agrobacterium tumefaciens LBA4404 strain with a binary vector plasmid pArtblue containing F3'5'H gene under control of CaMV35S promoter and nptII selectable marker gene. After inoculation, the explants were transferred to the co-cultivation medium. They were then...

Effect of arbuscular mycorrhizal fungal inoculation on growth, and nutrient uptake of the two grass species, Leptochloa fusca (L.) Stapf and Sporobolus robustus Kunth, under greenhouse conditions

The aim of our work was to assess the effect of inoculation with three arbuscular mycorrhizal fungi (AMF) (Rhizoglomus aggregatum (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oeh., Funneliformis mosseae (T.H. Nicolson and Gerd.) C. Walker and A. Schüssler. and Rhizoglomus intraradices (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oehl.), and a mixed inoculum of these AMF on root colonization, biomass...

Cooking and drying processes optimization of Pentadesma butyracea kernels during butter production

The cooking and the drying of the Pentadesma butyracea kernels are the main steps in the traditional method of extracting P. butyracea butter. In this work, the Response Surface Method with Central composite design was used to optimize the cooking and drying of Pentadesma kernels during P. butyracea butter production. The cooking and drying times, as well as the drying temperature of Pentadesma kernels are considered as...

Use of pectin in the storage of mangaba fruits (Hancorniaspeciosa Gomes) associated with refrigeration

The objective of this study was to evaluate the storage potential of mangaba fruits coated with pectin biofilm stored in biochemical oxygen demand (BOD) (22 ± 1°C) under modified atmosphere. Scanning electron microscopy (SEM) was used to analyze the physical and chemical changes, vitamin C content, soluble solid, titratable acidity and turgor pressure, and colour and physical structure of the fruits during...

Fermentable sugars and microbial inhibitors formation from two-stage pretreatment of corn stalk with variation in particle size and severity factor

Microbial inhibitors including weak acids, furan derivatives and phenolic compounds are key problems of cellulosic bio-fuels production by fermentation. Most of these inhibitors are sugars and lignin degradation compounds, which are almost unavoidable during pretreatment processes. While, most of the one stage pretreatment has been conducted at high severity factors of 3.5 or more to get high sugar yield, with increase...
