“…Sucrose utilization by fungi depends on their abilities of sucrase or fructosidase enzyme production. Sucrose was found to be slowly broken down into monosaccharides by wood decay fungi but was well used by waterborne fungi [16]. Other than a sugar source, sodium acetate was another good carbon source for P removal (13.15 %), while P removal was lower when M. circinelloides was cultured by glycerol, methanol, and ethanol (ranging from 8.06 to 8.64 %).…”

While bacteria have been primarily studied for phosphorus (P) removal in wastewater treatment, fungi and their ability to accumulate intracellular polyphosphate are less investigated. P-accumulating fungal strains were screened from soybean plants and surrounding soil by flask cultivation with potato dextrose broth and KH2PO4 in this study. Mucor circinelloides was selected for its high efficiency in P removal efficiency and high cellular P content. Neisser staining and growth-curve analysis confirmed that M. circinelloides stored polyphosphate intracellularly by luxury phosphate uptake. The effect of culture medium compositions on P removal efficiency and cellular P content was also investigated. Monosaccharides (such as glucose and fructose) and organic nitrogen (N, such as urea, and peptone) promoted fungi growth and P accumulation. M. circinelloides also preferred organic phosphates. When glucose, urea, and phytic acid sodium salt were used as the carbon, N, and P source, respectively, the maximum utilization efficiency was 40.1% for P and 7.08% for cellular P content. In addition, the potential of M. circinelloides for P removal from waste streams was investigated. Compared with the non-inoculated control culture, inoculation with M. circinelloides improved the soluble P removal in treating wastewater centrate, screened manure, and digested manure.

“…At first, the absence of a clear difference in the total cell yield of the 1% olive and raw linseed oil suspensions is surprising. For one thing, fungi are known to grow differently due to the use of different carbon sources (Sati & Bisht, 2006;Yang, Ke, & Kuo, 2000). In addition, lipases in the A. melanogenum suspensions are suspected to free different amounts of potentially utilizable fatty acids and glycerol compounds when using different oil types, because substrate-specific activities of fungal lipases are common (Avelar et al, 2013;Dheeman, Antony-Babu, Frías, & Henehan, 2011;Song, Qi, Hao, & Qu, 2008).…”

Dark homogenous fungal‐based layers called biofinishes and vegetable oils are key ingredients of an innovative wood protecting system. The aim of this study was to determine which of the vegetable oils that have been used to generate biofinishes on wood will provide carbon and energy for the biofinish‐inhabiting fungus Aureobasidium melanogenum , and to determine the effect of the oil type and the amount of oil on the cell yield. Aureobasidium melanogenum was cultivated in shake flasks with different types and amounts of carbon‐based nutrients. Oil‐related total cell and colony‐forming unit growth were demonstrated in suspensions with initially 1% raw linseed, stand linseed, and olive oil. Oil‐related cell growth was also demonstrated with raw linseed oil, using an initial amount of 0.02% and an oil addition during cultivation. Nile red staining showed the accumulation of fatty acids inside cells grown in the presence of oil. In conclusion, each tested vegetable oil was used as carbon and energy source by A. melanogenum . The results indicated that stand linseed oil provides less carbon and energy than olive and raw linseed oil. This research is a fundamental step in unraveling the effects of vegetable oils on biofinish formation.

“…The high mycelial biomass obtained in sucrose, glucose, starch and malt extract media can be attributed to the easy assimilation and break down of these carbon sources for use in the metabolic pathways of this species (Madan & Thind, 1998). Glucose, sucrose and starch have also been reported to produce the highest mycelial biomass growth for Pestalotiopsis submersus, Flagellospora penicillioides, and Tetrachaetum elegans, respectively (Sati & Bisht, 2006). Myo-inositol was reported to be a poor carbon source for mycelial biomass growth of Lepiota procera (Gbolagade, 2006).…”

“…Production of mycelial biomass a microfungus is influenced by many factors which includes the carbon and nitrogen nutrients used in the growth medium, light exposure, temperature, pH and aeration (Madan & Thind, 1998). Earlier studies on physiology of different Pestalotiopsis species were conducted using agar media (Mandahar & Narwal, 1970;Sati & Bisht, 2006;Ren et al, 2013).…”

Fungi are important decomposers in our ecosystem and are useful in metabolite production, bio-degradation and bio-sorption of different substrates and wastes through their mycelial biomass. Fungal species are known to have different preferences for their growth requirements. Two fungal species Pestalotiopsis and Pseudopestalotiopsis useful in many biotechnological applications were studied. Nutrient and physiological requirements for mycelial biomass production such as carbon and nitrogen, pH, light and temperature were investigated. Both fungal isolates were grown in liquid basal medium supplemented separately with various carbon and nitrogen source and incubated under different light, pH and temperature conditions for 15 days. In general, Pestalotiopsis sp. and Pseudopestalotiopsis sp. showed significant preferences for monosaccharide and disaccharide carbon source as compared to sugar alcohols and polysaccharides, whereas ammonium tartrate was more preferred as a nitrogen source compared to ammonium nitrate, ammonium sulphate and other ammonium salts. These two fungal species were able to grow and produce good mycelial biomass (223.33 mg for Pseudopestalotiopsis and 136.67 mg for Pestalotiopsis) at temperature range of 15°C to 30°C and (290.00 mg for Pseudopestalotiopsis and 256.67 mg for Pestalotiopsis) on media pH of slightly acidic to slightly alkaline. However, they showed no significant preferences between constant light, total darkness and alternate light conditions. The results from this study will be very useful for the mycelial biomass production of Pestalotiopsis sp. and Pseudopestalotiopsis sp. for their biotechnological applications.
