“…In line with our study, Askun (2006) found that Fusarium (82%), Penicillium (63%), and Aspergillus species (33%) were the most predominant fungi in corn compared to other genera. Askun (2006) also discovered that Aspergillus (19%) was one of the most common genera isolated from disinfected and non‐disinfected corn kernels.…”

“…As other studies reported, some of the most prevalent genera in corn were Aspergillus, Cladosporium, Fusarium, Penicillium, and Trichoderma (Bhattacharya and Raha, 2012;Niaz and Dawar, 2009;Ekwomadu et al, 2018). In line with our study, Askun (2006) found that Fusarium (82%), Penicillium (63%), and Aspergillus species (33%) were the most predominant fungi in corn compared to other genera.

Mycotoxigenic fungal contamination of corn poses significant health-related risks to consumers (Shad and Atungulu, 2017; Atungulu et al., 2018). The most prevalent mycotoxins that contaminate corn in the United States include aflatoxins, fumonisins, and deoxynivalenol (Abbas et al., 2002; Mohammadi Shad et al., 2019b; Robens & Cardwell, 2003; Wu et al., 2011). Chauhan et al. (2016) conducted a study on fungal infection, and aflatoxin contamination in corn collected from the Gedeo zone in Ethiopia and found that Aspergillus (75%), Fusarium (11%), Penicillium (8%), and Trichoderma (6%) were the predominant genera of fungi that contaminated the corn grains. Aflatoxins (produced by Aspergillus), deoxynivalenol, and fumonisins (produced by Fusarium) were also found in locally grown corn in 18 African nations during 2007 and 2008 (Probst et al., 2014). Lane et al. (2018) also found that Fusarium was the most abundant genus after exploring the fungal microbiome of corn during hermetic storage in the United States and Kenya.

“…A review of the literature reveals that these and other differential growth media have primarily been employed for the morphological characterization and identification of Aspergillus species. Aspergillus species were identified from maize kernels through their morphological characterization on CZA, MEA, and PDA [24]. Using CZA and MEA, Reddy et al [25] identified and distinguished five Aspergillus species isolated from rice grains in South Asia.…”

Morphological Characterization and Determination of Aflatoxin-Production Potentials of Aspergillus flavus Isolated from Maize and Soil in Kenya

et al. 2017

This study aimed at morphologically identifying Aspergillus flavus in soil and maize and at determining their aflatoxin-producing potentials. Five hundred and fourteen isolates obtained from maize and soil in Kenya were cultivated on Czapeck Dox Agar, Malt Extract Agar, Sabouraud Dextrose Agar, Potato Dextrose Agar, and Rose-Bengal Chloramphenicol Agar. Isolates were identified using macro-morphological characteristics. Micromorphological characteristics were determined using slide cultures. Aflatoxin production was determined by direct visual determination of the UV fluorescence of colonies on Coconut Agar Medium, Yeast Extract Sucrose agar, and Yeast Extract Cyclodextrin Sodium Deoxycholate agar and by Thin Layer Chromatography. Forty-three presumptive A. flavus isolates were identified; aflatoxin was detected in 23% of the isolates by UV fluorescence screening and in 30% by Thin-Layer Chromatography (TLC). The aflatoxins produced were: aflatoxin B 1 (AFB 1), aflatoxin B 2 (AFB 2), and aflatoxin G 1 (AFG 1); some isolates produced only AFB 1 , whereas others produced either AFB 1 and AFB 2 or AFB 1 and AFG 1. The highest incidence of A. flavus (63%) and aflatoxin production (28%) was recorded in samples from Makueni District. Isolates from Uasin Gishu (21%) and Nyeri (5%) were non-aflatoxigenic. Bungoma District recorded 11% positive isolates of which 2% were aflatoxin producers. The occurrence of aflatoxin-producing A. flavus emphasises the need for measures to eliminate their presence in food crops.

Ustilago maydis (DC) Corda, the causal agent of maize smut disease, can form enormous galls on cobs and cause significant yield losses under favorable conditions. In addition to yield losses, U. maydis may have an influence on the kernel quality in smutted cobs. The aim of this study was to determine presence of mycoflora on the cobs infected by U. maydis. A 2-year field experiment was conducted in Antalya Province. In the study, some maize cultivars belonging to various maize variety groups including dent corn, flint corn, sweet corn and popcorn were used as host plants. Inoculations were performed by injecting inoculum into ear silk of each cob of the plants in inoculated plots. For each treatment, control plots were also set up. When the kernels of cobs in control plots were mature enough to harvest, kernel samples in inoculated plots were taken from smutted cobs and investigated in terms of fungal flora. A total of 6 genera (Paecilomyces, Aspergillus, Penicillium, Acremonium, Fusarium, Rhizopus) were detected from the kernels in the smutted cobs. However, frequently isolated species were Aspergillus fumigatus, A. niger, A. parasiticus (A. flavus), Paecilomyces lilacinus, Penicillium citrinum, Fusarium solani, F. oxysporum and Rhizopus stolonifer. The most frequently isolated genus was Aspergillus (31.4%), while the lowest one was Penicillium (6.4%). The study showed that U. maydis may affect kernel quality of maize by harboring some fungal microorganisms in smutted cobs.
