“…Some organisms isolated in this study such as Proteus, Lactobacillus and Pseudomonas sp were shown to be associated with agricultural system such as corn cob. These results were supported by study carried out by Ekundayo et al, (2011) who isolated Lactobacillus, Proteus, Micrococcus, Klebsiella, Providencia and Clostridium sp and Bacillus subtilis from maize husks and maize cob.…”

Microbial succession refers to the changing microbial population in a natural of disturbed system. The aim of this study was to isolate and determine bacterial succession in anaerobic fermentation. Cow dung was collected from Oja-Oba in Ekiti State, Nigeria while the corn cob was collected from Ajayi Farms in Akure, Ondo State, Nigeria, and transported to Afe Babalola University (ABUAD) Farms, where it was ground into smaller pieces. One hundred kilograms of cow dung was mixed with water and transferred to digester A, 100 kg of corn cob was transferred to digester B and 50 kg each of cow dung and corn cob were transferred into digester C. Microorganisms were isolated using pour plate method from day 1 of the fermentation period and at 5 days intervals for the 30 days fermentation period. The bacterial isolates were identified on the basis of their morphological, biochemical characteristics and molecular analysis (DNA extraction, Polymerase Chain Reaction and gene sequencing). Some of the bacteria isolated were Escherichia coli CFT073, Arthrobacter citerus strain NEB577, Klebsiella aerogenes strain AR 0018, Pseudomonas aeruginosa PA01 and Acinetobacter lactucae strain ANC405. Microbial succession of bacteria also showed the dominant organisms belong to Phylum Proteobacteria, followed by phylum Firmicutes and phylum Acinetobacteria. The amount of gas compressed after fermentation in the digesters varied. Digester A- 60kg, Digester B- 12.5kg and Digester C- 64kg with percentage weight of gas of 54%, 50% and 56% respectively. The result from this experiment clearly showed that the anaerobic fermentation of cow dung and corn cob involved the interaction between diverse microbial populations at various stages of fermentation.

Article Info Received : 08.12.2015 Accepted : 20.01.2016 The aim of this work is to study the ability of several isolates belonging to Rhizobacteria (Pseudomonas and Bacillus) collected from several chickpea growing areas in Algeria, to control the mycelium growth of Fusarium oxysporum f. sp. ciceris. Interesting isolates were characterized for their morphological characteristics, physiological and biochemical activities as potential bio-control agent. Fungal inhibition tests were performed using plate assay and each isolate were tested for the production of protease, cyanide hydrogen, indole acetic acid, antifungal volatile and extracellular compound. According to API 50 CH, we are able to identify six Bacillus species (B. subtilis, B. circulans, B. lentus, B. aneurinilyticus, B. firmus, B. licheniformis; and with API 20NE test we have identified three Pseudomonas species (P. aeruginosa, P. luteola, P. fluorescens). The ability of bacterial isolates was varied in production of Protease, Gelatinase, Amylase, Cellulase, Acid Indole acetic, Lipase, Catalase and Cyanid Hydrogen. This is traduced in different rate of inhibition growth due to various extracellular compounds, where B61 (Bacillus aneurinilyticus) and P39 (Pseudomonas luteola) and P70 (Pseudomonas fluorescens) were the most efficient with 77 and 55.5% respectively, while B39 (Bacillus firmus) and P41 (Pseudomonas luteola) were the most efficient by volatile compounds with 70.5 and 77.5% respectively. Our results indicate that these bacteria isolates can be used in the biocontrol of Fusarium oxysporum f. sp. ciceris.

“…Different pathogen including Rhizoctonia solani, Macrophomina phaseolina and Fusarium solani are commonly attack on chilli and causing significant yield reduction (Madbouly and Abdelbacki, 2017). Annually 10-80% yield losses in chilli peppers occur due to disease (Ekundayo et al, 2011). Fusarium oxysporum causes Fusarium wilt disease, that frightening for the chilli production.…”

Capsicum annuum L. member of family Solanaceae is an important vegetable crop throughout the world. Fusarium wilt of chilli caused by Fusarium oxysporoum f.sp. capsici, is a serious destructive disease, which reduces its yield and is a major threat to the economy. Plant activators play an important role to manage soil born disease. In current study, a pot experiment was carried out under greenhouse conditions in the research area of Plant Pathology Department, University of Agriculture, Faisalabad. Five plant activators K2HPO4, CaCl2, Benzoic acid, Salicylic acid and Alpha-Tocopherol were used to manage the Fusarium wilt of chilli. Soil drenching of each plant activator was applied at three different concentrations 0.25%, 0.5% and 0.75% after transplantation. Results showed that the minimum incidence of disease, maximum length of shoot, length of root was revealed by K2HPO4 at 0.75% concentration. While benzoic acid exhibit maximum shoot fresh weight, maximum shoot dry weight, fresh root weight and dry root weight at 0.75% concentration. Maximum fresh leaf weight showed by salicylic acid whereas maximum dry leaf weight exhibited by alpha-tocopherol at 0.75% concentration. It was concluded that K2HPO4 at 0.75% concentration is effective to manage Fusarium wiltof chilli that can be used to manage disease in future.
