“…Schizosaccharomyces pombe was detected in many countries and regions of the world in freshly tapped sap or in fermenting palm sap e.g. in Pakistan (Ahmad et al 1954 ), in Burkina Faso (Ouoba et al 2012 ), in Nigeria (Amanchukwu et al 1989 ; Boboye and Dayo-Owoyemi 2008 ; Faparusi and Bassir 1971 ; Obisanya et al 1987 ; Sanni and Lönner 1993 ), in North Africa (Castelli and Haznedari 1968 ), in India (Shamala and Sreekantiah 1988 ), Sri Lanka (Atputharajah et al 1986 ; Field and Wills 1998 ; Vidanapathirana et al 1983 ) and Thailand (Udomsaksakul et al 2018 ). S. octosporus was isolated from palm wine fermentation in Nigeria (Chilaka et al 2010 ).…”

The fission yeast genus Schizosaccharomyces contains important model organisms for biological research. In particular, S. pombe is a widely used model eukaryote. So far little is known about the natural and artificial habitats of species in this genus. Finding out where S. pombe and other fission yeast species occur and how they live in their habitats can promote better understanding of their biology. Here we investigate in which substrates S. pombe, S. octosporus, S. osmophilus and S. japonicus are present. To this end about 2100 samples consisting of soil, tree sap fluxes, fresh fruit, dried fruit, honey, cacao beans, molasses and other substrates were analyzed. Effective isolation methods that allow efficient isolation of the above mentioned species were developed. Based on the frequency of isolating different fission yeast species in various substrates and on extensive literature survey, conclusions are drawn on their ecology. The results suggest that the primary habitat of S. pombe and S. octosporus is honeybee honey. Both species were also frequently detected on certain dried fruit like raisins, mango or pineapple to which they could be brought by the honey bees during ripening or during drying. While S. pombe was regularly isolated from grape mash and from fermented raw cacao beans S. octosporus was never isolated from fresh fruit. The main habitat of S. osmophilus seems to be solitary bee beebread. It was rarely isolated from raisins. S. japonicus was mainly found in forest substrates although it occurs on fruit and in fruit fermentations, too.

“…Perhaps more informative for fission yeast ecology are the cases where fission yeasts have been discovered in natural substrates such as palm wine (a fermentation of palm sap; Theivendirarajah & Chrystopher, ; Amanchukwu, Obafemi, & Okpokwasili, ; Ouoba et al, ). Fission yeast are also present in natural fermentations of fruits such as Coffea arabica and Theobroma cacao (from which coffee and cocoa beans are harvested, respectively; Silv, Schwan, Sousa Dias, & Wheals, ; Schwan & Wheals, ).…”

“…Enumeration of total heterotrophic bacteria was carried out using the stated procedures which have been previously reported (Chikere et al, 2009 The enumeration of Total Culturable Hydrocarbon Utilizing Bacteria (TCHUB) was done by using the vapour phase method (Atuanya and Ibeh, 2004 (Amanchukwu et al, 1989a;1989b;Chikere and Chijioke-Osuji, 2006). The plates were incubated at 28°C±2°C for seven (7) days and colonies were counted from triplicates and mean values were recorded in colony forming units per gram (Cfu/g).…”

Laboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×10 7 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×10 5 Cfu/g to 1.24×10 6 Cfu/g. Statistical analyses showed significant difference for the two conditions (p ≥ 0.05). The total culturable heterotrophic fungal count in the Eichhornia crassipes recipe treatment increased from 5.36×105 Cfu/g to 2.50×10 7 Cfu/g respectively. The total culturable hydrocarbon utilising bacteria in Eichhornia crassipes treated polluted mangrove soil increased from 2.52×104 Cfu/g to 3.81×10 7 Cfu/g. Statistical analyses showed significant difference at p ≥ 0.05 level for the two conditions (Eicchornia crassipes nutrient treated soil and control). The total culturable hydrocarbon utilising fungal counts increased significantly for both the control and Eichhornia crassipes treatment. There was no regular trend in pH changes in all the conditions. The conductivity value of the Eichhornia crassipes recipe treated soil decreased progressively. Phosphate, nitrate, %total organic carbon, Total Hydrocarbon Content (THC). Studies using Gas chromatographic analyses showed that in the Eichhornia crassipes recipe treated polluted mangrove soil, 0, 58.92 and 75.36% were lost at zero hour, 28th day and 70th day respectively. In addition, in the control experimental set-up, 0, 7.14 and 13.42% of TPH were lost at zero hour, 28th day and 70th day respectively. There was no significant difference between the control experiment and Eichhornia crassipes (p = 0.054). The use of organic nutrient sources such Eichhornia crassipes recipe/nutrient powder is of good use as source of limiting nutrient needed for bioremediation of crude oil impacted medium.
