Moringa Oleifera Lam

Cassava starch has many known applications in food, paper, glue and textile industries, including even biodegradable packaging. In small and medium industries, the starch is obtained by washing the peeled and grinded manioc roots, followed by leaving the washwater for settling before drying the concentrated slurry. Since starch particles are very fine and have a low density, their settling time is high, resulting in a batch operation that lasts for 18 to 24 h. Therefore, it becomes suitable to form larger and heavier starch sets by means of applying coagulants, allowing the particles to settle faster. In the work reported here, the natural coagulant M. oleifera seed extract was used to decrease the settling time of the cassava starch. The effect of the initial concentration of the particles and the coagulant content on the final sedimentation time was evaluated on the batch settling tests. The results showed that the use of the coagulant reduced the sedimentation time in a beaker from 14h to 2h, allowing a quick batch operation.

Moringa Oleifera Lam

Wastewaters from textile industries are known for their difficulty to treat, several alternative technologies are applied for their treatment. In this context, the study examined a hybrid treatment system, composed of electrocoagulation combined with a natural coagulant (extract of Moringa oleífera lam seeds) to remove reactive dye Blue 5G aqueous solutions. The work evaluated the use of milder operating conditions to improve the efficiency of treatment, with reduced demands for electrical power and coagulant.  The following factors were evaluated: electric current intensity, natural coagulant concentration and hydraulic retention time. A quadratic model was adjusted and validated at a 5% significance level. The overall optimization resulted in conditions of 0.28 A for electrical current intensity, 1000.00 mg L-1 of aqueous extract of Moringa oleífera lam and 5 min for hydraulic retention time. While operating under optimal conditions, the removal of 71.38% of color and 5.22 mg L-1 of iron residual concentration was achieved.

Studies on aflatoxin seed contamination of groundnut (Arachis hypogaea) in storage and its management using seed extract of Moringa oleifera and rhizome of Zingiber officinale was carried out on diseased seeds collected from Dutsin-Ma, Kurfi and Safana Local Government Areas of Katsina State, Nigeria between March and July, 2019. Aspergilus niger, A. flavus, A. ochraceus, A. tamari, A. parasitica, Rhizotonia spp, mucor spp and F. oxysporum were isolated. A. niger was the most frequently occurring pathogen in all the locations in March, 2019 with a range of 9 in Kurfi to 13 Dutsin-Ma and between 14 in Kurfi and 22 in Dutsin-Ma in July while the least was Mucor with a range of 3 in Dutsin-Ma and 6 in Kurfi both in July. Pathogenicity test conducted illicit rot in the healthy groundnut seeds. A. niger and A. flavus which were the most virulent pathogenic fungi responsible for aflatoxin contamination in groundnut seeds were controlled with the two extracts. Z. officinale was found to be more effective in the control of A. niger than M. oleifera at 40 g/L with inhibition of 60.32 % and at 120 g/L with inhibition of 87.33 % compared to M. oleifera which inhibited A. niger mycelial at 40 g/L by 59.79 % and at 120 g/L by 73.53 %. M. oleifera however, proved more efficacious in the management of A. flavus than Z. oficinale at 40 g/L and 80 g/L with percentage growth inhibition of 60.79 % and 62.47 %, respectively compared to a lower inhibition of 60.52 % and 60.94 % at 40 g/L and 80 g/L of Z. officinale, respectively. In both cases, the two extracts proved more effective on A. niger than A. flavus. It is therefore, recommended that extracts of Z. officinale and M. oleifera at different concentrations can be used to effectively manage rot pathogens of groundnut seeds in storage by farmers.
