“…This means that the substrate is a poor source of carbon and energy for the growth of fungus. Sawdust of Abora wood (Mitragyna ciliata) contains over 60% crude fiber consisting of a large proportion of lignin (Grant and Long, 1981;Okafor et al, 2007). The sugar content of all the culture media steadily decreased as fungal incubation and mycelia weight increased.…”

Common agro-wastes found in Lagos, Nigeria (cassava shavings, corncob, sawdust, and sugarcane pulp) were compared with glucose and lactose as fermentation substrates for Penicillium chrysogenum PCL501. Cassava shavings significantly (P<0.001) produced the highest amount of mycelia weight (0.43 ± 0.02 mg/ml) than all the other substrates. This was followed by corncob with peak mycelia weight of 0.33 ± 0.02 mg/ml. Peak mycelia weight of 0.27 ± 0.01 mg/ml was equally obtained with glucose and sugarcane pulp whereas lactose gave a slightly lower peak of 0.25 ± 0.01 mg/ml. Sawdust gave the least mycelia weight of 0.13 ± 0.01 mg/ml. Total sugar content of all the culture media steadily decreased as fungal growth progressed indicating that the organism utilized carbohydrates for growth and mycelia formation. Cultures containing cassava shavings and sawdust gave high protein peaks of 0.84 ± 0.05 and 0.65 ± 0.03 mg/ml respectively. Cultures containing corncob, glucose, lactose and sugarcane pulp yielded lower protein peaks of 0.37 ± 0.02, 0.30 ± 0.02, 0.24 ± 0.02 and 0.18 ± 0.01 mg/ml respectively. The results suggest that cassava shavings, corncob and sugarcane pulp could serve as cheap fermentation substrates for the growth of the fungus. Of all the substrates investigated, cassava shavings have the best potential to serve as substrate for fermentation by Penicillium chrysogenum PCL501.

“…Numerous filamentous fungi naturally thrive on plant wastes because they can penetrate the dead plant matter and utilize the cell wall components as growth substrates (Grant and Long, 1981). Among them is Penicillium species, a common contaminant which colonizes a wide range of materials including wood, fabrics and leather objects.…”

“…It can be corrupted by various microscopic organisms and growths. These living beings can deliver a direction battery of extracellular chemicals fit for corrupting cellulose and in addition some other plant celldivider polymers [51]. Bioconversion, especially, enzymatic hydrolysis of cellulosic materials to helpful items has extraordinary potential.…”

“…Also the ease of genetic manipulation, regular supply due to absence of seasonal fluctuations and rapid growth of micro organisms make their exploitation attractive. Pathogenic fungi are known to inhabit food materials just as numerous filamentous fungi naturally thrive on plant wastes because they can penetrate the dead plant matter and utilize the cell wall components as growth substrates (Grant & Long, 1981).…”

The methanolic leaf extracts of Carica papaya, Chromolaena odorata, Alcohorneae laxiflora and Elaeis guineensis were investigated for antifungal activity against Penicillium minioluteum JX 442528 and Aspergillus niger JX 442527 in the mycology laboratory of Babcock University, Ilishan remo.. Also, common agro-wastes (wheat bran, rice bran and corn cobs) served as treatments as components of bioreaction for Penicillium minioluteum and Aspergillus niger both in submerged and solid state fermentations. Fungal growth inhibition was recorded with extracts from Carica and Chromolaena spp Extract of Elaeis guineensis extract has the lowest antifungal effect on Penicillium minioluteum. The solid state fermentation has higher enzyme activity compared to the submerged fermentation. Highest production for the 4 enzymes assayed for was observed on wheat bran media, using the SPSS statistical package. For industrial enzyme production, these cultural characteristics could therefore be critical.
