“…Substantial amounts of hydrocarbons were found only in the G. mellonella cuticle. Although the widespread ability of fungi to grow on hydrocarbons is well known (Sancholle and Lö sel, 1995) information concerning utilization of hydrocarbons present in insect cuticle by pathogenic fungi is rare (Napolitano and Juarez, 1997). Similarly, studies on fungal lipases hydrolyzing triacylglycerols concentrate on species medically important or with biotechnological applications (Cole, 1996;Sancholle and Lö sel, 1995), while reports on lipases produced by entomopathogenic fungi are unique (Khachatorians, 1996;Gillespie et al, 2000).…”

“…The influence of exogenous lipid substrates on fungal growth and differentiation, intracellular and membrane lipid composition, membrane fluidity, mitochondrial structure as well as drug tolerance is well documented (for review see Sancholle and Lö sel, 1995). Further studies on the influence of fatty acids detected in insect cuticle on the C. coronatus in vitro growth are necessary to answer the major questions concerning the role of particular cuticular fatty acids in the C. coronatus pathogenesis.…”

“…For these reasons, the microbial conversion of these wastes can improve their nutritional value and transforming them into animal feed with high quality (Villas-Boas et al, 2002). Most fungi are capable of degrading various varieties of substrates (Sancholle and Losel, 1995) and their role in the nutrition of animal (Belewu andBelewu, 2005 andBelewu, 2006).Moreover, Akinfemi and Ladipo (2013) showed that fungal treatment of sawdust enhances its nutrient contents and in vitro digestibility. The biological and urea treatments of grape trees by-products improved nutrients digestibility and nutritive values (under publication).…”

This experiment was conducted to study the effect of chemical and biological treatments of pruning peach trees by-products (PTBP) on chemical composition, degradability, cell wall constituents, digestibility and nutritive value and its feeding effect on productive performance of growing sheep. Thirty Ossimi lambs with average body weight 18.00±0.20 kg and 4 months old were used in this study for 120 days. Lambs were distributed into five similar groups (6 lambs each) and randomly assigned to five experimental rations. The five respective rations composed of concentrate feed mixture (CFM) + roughage (PTBP), the control ration (R1) contained untreated PTBP; (R2) treated PTBP withTrichoderma reesei; (R3) treated PTBP with Trichoderma viride;(R4) treated PTBP with Trichoderma reesei + Trichoderma viride and (R5) 3% urea treated PTBP. The DM, OM and CP disappearance and effective degradability (ED) va lues were in situ determined. The digestibility and nutritive values of experimental rations were determined using fifteen adult Ossimi rams. Rumen liquor and blood samples were collected at the end of collection period. The results showed that fractions of DM (a&b) and (ED) were significantly (P<0.05) increased with treated PTBP either with urea or fungi compared to control (untreated PTBP). The highest degradable values of DM, OM and CP were observed with R4. Nutrient digestibility and feeding values (TDN and DCP) were higher (P<0.05) for rations containing treated PTBP than control. The highest values of TDN and DCP were observed for R4. Digestibility of cell wall constituents (NDF, ADF, cellulose and hemicellulose) were improved by treatments. Concentrations of rumen parameters (NH3-N and TVFA's) were significantly increased by treatments. However, no significant differences were found in blood constituents (total protein, albumin, globulin, GOT, GPT and urea) among the different experimental groups. Blood constituents were generally normal in all experimental groups. Growth performance with respect to total body weight gain and average daily gain (ADG) were improved by biological treatments. The same trend was observed for feed conversion and economic efficiency and the best values were recoded with R4. It was concluded that inclusion of treated PTBP to rations of growing Ossimi lambs could improve their performance especially treatment of PTBP with fungi.

“…polyunsaturated fatty acid (LCPUFA) arachidonic acid (ARA ; 20 : 4, n-6). LCPUFAs are important both nutritionally and pharmacologically and there is much interest in developing microbial processes for their production (Ratledge, 1993 ;Sancholle & Lo$ sel, 1995 ;Leman, 1997). They are directly incorporated into membranes of the central nervous system and hence affect brain and nerve development (Willatts et al, 1998).…”

cerevisiae. This indicated that the M. alpina ∆9-desaturase had a substrate preference for stearic acid (18 :0) rather than palmitic acid (16 :0). Genomic clone ∆9-2 (ole2) also encoded a protein of 445 aa which had 86 % identity to the ∆9-1 and LM9 proteins and whose ORF also complemented the yeast ole1 mutation. The transcript from this gene could only be detected in one of the six M. alpina strains tested, suggesting that its expression may be strainspecific or induced under certain physiological conditions.
