“…[15] reported Rhizopus specie, Aspergillus specie, Saccharomyces species, Penicillium species and Fusarium species to be responsible for spoilage of Cucumber, Mango and Pineapple fruits. Future research is needed to inhibit fruit and vegetable spoilage due to pathogens, perhaps using plants and herbal bioactive compounds themselves that had been demonstrated in several instances [20][21][22].…”

Cucumber fruit (Cucumis sativus L.) is believed to have originated from Southern Asia and fourth most important vegetable after tomato, cabbage and onion. The objective is to isolate and identify fungi responsible for rot of cucumber (Cucumis sativus L.) in the study area. Potato dextrose agar was used as growth medium. Three fungal pathogens (Aspergillus flavus, Rhizopus stolonifer and Aspergillus brasiliensis) were identified through pathogenicity test to be causing rot of Cucumber fruit in Jimeta markets (Gwari Market, Jimeta Modern Market and Jimeta Shopping Complex Market), Yola North of Adamawa state. Isolation and identification of pathogens responsible for cucumber fruit rot in Jimeta Markets were carried out, where Rhizopus stolonifera had the highest (25-48%) frequency of occurrence while Aspergillus flavus was the least (22-38%). From the study, it is concluded that Aspergillus brasiliensis, Rhizopus stolonifer and Aspergillus flavus were found out to be the fungal pathogen that caused rot of Cucumber (Cucumis sativus L.) fruit in the study area. The vulnerability of Cucumber fruit to fungal rot is not far from the poor way and manner at which the fruits are conveyed, stored and traded in the study area. It is recommended to farmers and fruit vendors to be conveying perishable fruits in soft bags and stored in cool dry places.

The formulation of hypotheses and the recommendation of experiments as the subsequent stages of the research process are both brought about as a result of the utilization of complicated computer models that make it possible to represent intricate biological processes. Because these systems rely on random data, this is a necessity for all parametric statistical assessment procedures. When the diagnostic tests reveal that the residuals make up a pattern, there are a few different treatment choices available to choose from. Two of these alternatives include running a nonparametric analysis or switching to a new model. In this study, we use the Wald-Wolfowitz runs test as a statistical diagnosis tool to determine whether or not the randomization conditions have been met. The runs test found that there were 5 total runs, although the randomness assumption predicted 7.46 runs. The null hypothesis is not rejected since the p-value is greater than 0.05; this suggests that there is no convincing evidence of the residuals' non-randomness; rather, the residuals represent noise. In addition, the Grubb’s outlier test shows no indication of an outlier, further corroborate the scenario of the adequacy of the modified Gompertz model used in the fitting of the growth of Shigella flexneri.

<abstract>Juru River is one of the most polluted rivers in Malaysia. A dye-degrading bacterial consortium has been isolated from the river's sediment. This consortium JR3 consists of <italic>Pseudomonas aeruginosa</italic> MM01, <italic>Enterobacter</italic> sp. MM05 and <italic>Serratia marcescens</italic> MM06, which were able to decolorize up to 700 ppm of the Reactive Red 120 (RR120) dye under optimal conditions with limited substrate available. Substrate inhibition kinetics were investigated, and, based on the best model, Aiba, the maximum growth rate was 0.795 h–1, while the saturation constant and inhibitory constant were 0.185% and 0.14%, respectively. In addition, the influence of various metal ions on the growth and decolorization rate of this bacterial consortium on RR120 was investigated. Chromium showed the weakest effect on the decolorization of 200 ppm RR120, with 73.5% removal and bacterial growth of 11.461 log CFU mL–1. Zinc yielded the second weakest effect, followed by silver and lead, with percentages of RR120 decolorization of 63.8%, 54.6% and 50.5%, respectively. Meanwhile, cadmium, arsenic and copper reduced the decolorization of RR120 in consortium JR3 by half. Mercury strongly inhibited decolorization by 32.5%. Based on the least inhibited heavy metal in RR120 decolorization activity of consortium JR3, the best inhibitory kinetic model was Levenspiel, with a maximum growth rate of 0.632 h–1, while the saturation constant and inhibitory constants were 15.08% and 0.5783%, respectively. The metal-tolerant azo dye-degrading bacterial consortium will be very useful in dye remediation in metal-laden polluted environments.</abstract>
