Bioremediation of Heavy Metals in the Soil by Pseudomonas aeruginosa and Trichoderma harzianum Using Solanum lycopersicum as Test Plant

Abstracts

This study determined the heavy metal concentrations of contaminated stream water and assessed the heavy metal contents of pre- and post-cropped sterilized soil. It also determined the the heavy metal uptake of the S. lycopersicum plant. This was with a view to assessing the potential of Pseudomonas aeruginosa and Trichoderma harzianum for transforming heavy metals in heavy metal contaminated stream water. Experimental pots containing 3000 g of sterilized soil was used for this experiment whereby 60 sample pots were used with various treatments in this study. Solanum lycopersicum seeds were raised in the nursery for a period of 3 weeks and treatments applied just before transplanting into the experimental pots. The plants were left for a week so as to be established properly and overcome transplanting shock before watering with the contaminated stream water. Heavy metal analysis using Atomic Absorption Spectroscopy (AAS) method was carried out on the contaminated stream water to determine the amount of heavy metal in the stream water before the commencement of the experiment. The contaminated stream water was applied to the pots in measured quantities; 0, 5 and 10%. Pre and post soil heavy metal analysis were carried out on the soil samples. At harvest, plant tissues were analysed for heavy metals using AAS method. The results showed that heavy metals were present in high concentration in the stream water sample. The values of the heavy metals in the stream water sample used for watering were Iron – 138.15 mg/L, Zinc – 68.4 mg/L, Lead – 7.89 mg/L and Copper – 8.98 mg/L. Heavy metal analysis of the soil and all the treatments revealed that treatments with P. aeruginosa inoculation had the lowest level of Iron, Copper, Zinc and Lead followed by treatments inoculated with T. harzianum. The study concluded that the use of contaminated stream water for irrigation could be a potential source of heavy metals in tomato. However, inoculation of microorganisms for the treatment of the heavy metal contaminated sites was effective Phytoremediation,for increased health, growth and yield of tomato fruits.

Insights on Pharmacological Properties of Combretum leprosum Mart.

Abstracts

Combretum leprosum Mart. is a plant widely used in folk medicine; several studies revealed anti-inflammatory, antinociceptive, toxic, antiproliferative, antibacterial, antiparasitic, neuroprotective and gastroprotective effects, among other properties. However, there are no reports on evaluation of preparations obtained from this species’ tissues, exploring biological responses of macromolecular components, such as proteins, common active agents. Proteins, such as lectins, promote important pharmacological results due to specific interaction with carbohydrates or glycoconjugates. In this work, a protein fraction obtained from a saline extract of C. leprosum leaves was evaluated for anti-inflammatory potential in a paw edema assay induced by carrageenan in Wistar rats. A significant anti-edematous effect was observed after 3 h (100 mg protein/kg) and 6 h (30 mg/kg and 100 mg/kg). The saline extract and protein fractions showed lectin activity, inhibited by D-(+)-mannose, D-(+)-trehalose dihydrate, D-(+)-galactose and D-fructose. Conclusively, leaves of C. leprosum contained proteins and lectin(s), promising anti-inflammatory agents. A vision of C. leprosum pharmacological properties is also approached.

Adhesion of Heterotrophic Bacteria on the Surface of Containers Used for Well Water Storage in Garoua (North Cameroon)

Abstracts

Aims: The abundance of heterotrophic bacteria adsorbed on the walls of four types (polypropylene, glass, aluminium, clay) of containers used for well water storage in Garoua was compared. 

Methodology: Water samples were obtained from two wells. In each well water sample, 3 sterilized slides of each type of container were introduced, at mid-depth from the surface. Their immersion times were respectively 24, 48 and 72 h. After an immersion time, slides were aseptically removed from the water samples and transferred into sterile test tubes containing 10 ml of saline. The resulting bacterial suspension was used to determine abundance of heterotrophic bacteria adsorbed on the slides. 

Results: The maximum abundance of adsorbed bacteria (8.06x104 CFU/cm2 to 2.47x106 CFU/cm2) was obtained on the clay slide while the minimum (45 CFU/cm2 to 5.90x103 CFU/cm2) was recorded on the aluminium slide from first to third day of water storage. The bacterial abundance differs significantly depending on the slide type and the duration of water storage (P <0.001). 

Conclusion: Rather than using massively clay pots for drinking water storage, people in North Cameroon are recommended to use metallic or glass containers to reduce bacterial adhesion.

Responses of Rhopalosiphum padi (L.) (Homoptera: Aphididae) on Different Wheat Cultivars under Laboratory Conditions

Abstracts

Bird cherry-oat aphid, Rhopalosiphum padi (L.), a polyphagous species with a worldwide distribution, is an important pest of wheat as well as the main vector of barley yellow dwarf virus. The development, survivorship, and life table parameters of R.padi were evaluated in a growth chamber on seven wheat cultivars as follows: ACA 315, Baguette 12 P, BioInta 1002, BioInta 2004, Buck Meteoro, Klein Yarará and LE 2330 at controlled conditions (20±1°C; about 70% RH; 14h photophase). The development times of immatures ranged from 6.6 days on Buck Meteoro to 9.9 days on ACA315, whereas immature survival was 90 to 100%. The intrinsic rate of increase (rm) for ACA 315, Baguette 12 P and BioInta 2004 were the highest. Jackknife estimates of rm ranged from 0.327 to 0.204 females/female/day on BioInta 1002 and ACA315, respectively. The mean population generation times (T) on these hosts ranged from 10.91 to 19.66 days. The highest net reproductive rate (R0) were on BioInta 2004 (98.98 females/female/generation) and the lowest on BioInta 1002, Buck Meteoro, Klein Yarará and LE 233 (35.32 to 39.59). Because of the high coefficient of determination (pseudo-R2) values in Gompertz and Weibul models, survival data from different cultivars had a good fit to both models. The results pointed ACA 315, Baguette 12 P and partially BioInta 2004 as the least suitable host plants, indicating that they were the most resistant to R. padi among the cultivars we tested.
