Biodegradation potential of immobilized bacteria in the treatment of Tannery Industrial effluents from industrial estates in Kano State, Nigeria

Bayero Journal of Pure and Applied Sciences, 2021

Industrial Effluents Samples from Gashash Tanneries (TAN1) in Bompai Industrial estate, Larabee T... more Industrial Effluents Samples from Gashash Tanneries (TAN1) in Bompai Industrial estate, Larabee Tannery Industry (TAN2) in Sharada Industrial estate and Z Tannery Industries (TAN3) in Challawa Industrial estate, Kano State, Nigeria were collected over a period of six months (August 2017 to January 2018) for assessing the biodegradation potentials of bacteria in the treatment of organic pollutants within the effluents. Bacteria were isolated from the effluents and immobilized on agar-agar. Different masses (5 g, 10 g, 15g, 20 g, and 25 g) of the bacteria were used in the treatment of 250 ml of the effluents for ten days in a shaker incubator (Gallenkamp-OC-4364-L) at the temperature 30 °C and speed of 60 rpm. Pre-treatment analysis of the effluents for Temperature, pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solid (SS) and Total Dissolved Solids (TDS) gives the following results; temperature (ºC) ranged (26.38±3.81-30.33±3.79); pH (5.35±1.57-9.00±0.78...

In vitro Antifungal, Antibacterial and Cytotoxicity Studies of Solvents Extracts of Some Medicinal Plants (Echinaceae angustifolia, Myosotis scorpioides, Detarium microcarpum and Terminalia mollis) Collected in Girei Adamawa State – Nigeria

Bioassays including growth inhibition of phytopathogen ( Pythium aphanidermatum ), Minimum Inhibi... more Bioassays including growth inhibition of phytopathogen ( Pythium aphanidermatum ), Minimum Inhibition Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Brine Shrimp lethality test of the dichloromethane (DCM) and methanol extracts of Echinaceae angustifolia, Myosotis scorpioides, Detarium microcarpum and Terminalia mollis were carried out. The result of growth inhibition on Pythium aphanidermatum revealed that the DCM extract of Detarium microcarpum has the highest growth inhibition (75%) followed by DCM extract of Myosotis scorpioides (45%). The result indicated that both DCM and MeOH extracts of the plants were active in the MIC and MBC [b1] . The result of the Brine Shrimp Test (BST) revealed LC 50 of 91.985µg/ml (toxic) for the MeOH extract of E. angustifolia and LC 50 of 1540.00µg/ml (non-toxic) for MeOH extract of Detarium microcarpum . The result of the study has availed the potentiality of these plants as source of important phytochemicals that are active ag...

Isolation and Identification of Phytopathogenic Fungi from Infected Plant Parts

The fungal isolates were Alternaria spp (Tomato early blight), Fusarium oxysporum (Fusarium wilt), Fusarium solani (daming off and root rot), Aspergillus flavus (Ear rot) and Collectotricumspp (Anthracnose).Methods: They were isolated from infected plant parts and were identified on the basis of colony morphology andlacto phenol cotton blue (LPCB) stains were used to identifymicroscopic examination of spore structures. Pure cultures of the isolates were sub cultured and transferred onto differential media; potato dextrose agar, malt extract agar, czapek yeast extract agar and czapek dox agar for species identification using macro morphological characteristicsThe morphological characteristics of these fungal elements showed various kinds of spores have been identified up to genus/species level.Results: This study proves rapid and less expensive techniques to validate a primary alarm of ...
