Última FRUITY AROMA PRODUCTION BY Ceratocystis fimbriata IN SOLID CULTURES FROM AGRO-INDUSTRIAL WASTES Rev. Microbiol. Bramorski,Adriana; Soccol,Carlos R.; Christen,Pierre; Revah,Sergio. Solid state fermentations were carried out to test the efficacy of Ceratocystis fimbriata to grow on different agro-industrial substrates and aroma production. Seven media were prepared using cassava bagasse, apple pomace, amaranth and soya bean. All the media supported fungal growth. While amaranth medium produced pineapple aroma, media containing cassava bagasse, apple pomace and soya bean produced a strong fruity aroma. The aroma production was growth dependent and the maximum aroma intensity was detected a few hours before or after the maximum respirometric activity. Sixteen compounds were separated by gas cromatography of the components present in the headspace and fifteen of them were identified as acid (1), alcohols (6), aldehyde (1), ketones (2)...

Ano: 1998 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37141998000300012 Amylase production by solid-state fermentation of agro-industrial wastes using Bacillus sp. BJM Saxena,Rajshree; Singh,Rajni. Solid state fermentation was carried out using various agro- industrial wastes with the best amylase producing strain isolated from soil. Different physicochemical conditions were varied for maximum enzyme production. The strain produced about 5400 units/g of amylase at 1:3 moisture content, 20% inoculum, after 72 h of incubation with Mustard Oil seed cake as the substrate. The optimum temperature and pH of the enzyme activity were found to be 50ºC and 6 respectively. The enzyme was found to be thermostable at 70ºC for about 2 h without any salt. It showed stability at pH range 5-7. The metal ions as Na+, Ca++, Mg++ and Co++ enhanced the enzyme activity.

Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822011000400014 Effect of acid hydrolysis and fungal biotreatment on agro-industrial wastes for obtainment of free sugars for bioethanol production BJM El-Tayeb,T.S.; Abdelhafez,A.A.; Ali,S.H.; Ramadan,E.M.. This study was designed to evaluate selected chemical and microbiological treatments for the conversion of certain local agro-industrial wastes (rice straw, corn stalks, sawdust, sugar beet waste and sugarcane bagasse) to ethanol. The chemical composition of these feedstocks was determined. Conversion of wastes to free sugars by acid hydrolysis varied from one treatment to another. In single-stage dilute acid hydrolysis, increasing acid concentration from 1 % (v/v) to 5 % (v/v) decreased the conversion percentage of almost all treated agro-industrial wastes. Lower conversion percentages for some treatments were obtained when increasing the residence time from 90 to 120min. The two-stage dilute acid hydrolysis by phosphoric acid (1.0 % v/v) followed by...

Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822012000400037 Utilization of Agro-industrial Wastes for the Simultaneous Production of Amylase and Xylanase by Thermophilic Actinomycetes BJM Singh,Renu; Kapoor,Vishal; Kumar,Vijay. Agro-industrial wastes such as sugarcane bagasse, wheat bran, rice bran, corn cob and wheat straw are cheapest and abundantly available natural carbon sources. The present study was aimed to production of amylase and xylanase simultaneously using agro-industrial waste as the sole carbon source. Seven thermophilic strains of actinomycete were isolated from the mushroom compost. Among of these, strain designated MSC702 having high potential to utilize agro-industrial wastes for the production of amylase and xylanase. Strain MSC702 was identified as novel species of Streptomyces through morphological characterization and 16S rRNA gene sequence. Enzyme production was determined using 1% (w/v) of various agro-industrial waste in production medium containing...
