Efeito de diferentes níveis de pH e de melaco na sobrevivência de Trichoderms harzianum e Bacillus subtilis em compostos orgânicos. Repositório Alice
PEREIRA, J. C.; CHAVES, G. M.; ZAMBOLIM, L.; MATSUOKA, K..
Procurou-se avaliar o efeito de diferentes niveis de pH e melaco de cana na sobrevivencia desses micoparasitas em composto organico. Utilizou-se o vermicomposto e o pH foi corrigido mediante a adicao de acido acetico glacial. Apos o periodo de dissecacao, promoveu-se a correcao do pH e incorporacao do melaco e posterior fumigacao. Os dados obtidos foram submetidos a analise estatistica e efetuadas comparacoes quadraticas e lineares entre niveis de pH dentro dos niveis de melaco. Os resultados obtidos mostraram que, na medida em que se reduz o nivel de pH, obtem-se maiores populacoes de T. harzianum e menor populacao de B. subtilis. Contudo, houve crescimento das populacoes na medida em que se elevou o nivel de melaco, independente do nivel de pH. Esses...

Screening of different fungi for decolorization of molasses BJM
Seyis,Isil; Subasioglu,Tugba.
The decolorization of molasses by 17 different fungi in 2 media was studied. Trichoderma viride showed the highest decolorization yield (53.5%) when cultivated at 30°C for 7 days in Medium 1 which contained the molasses which was diluted to 40 g/L in distilled water. The other Trichoderma species and Penicillium sp. also gave similar results of 40-45%. Decolorization yield was increased by adding peptone and yeast extract to the production medium except Penicillium sp. Growth rate was not related to decolorization yet pH value was. When the pH decreased below 5.0 after the incubation, the decolorization yield increased. Although reducing sugar in culture broth decreased with decreasing color intensity, there was no connection between protein utilization...

Enhanced ethanol production at commercial scale from molasses using high gravity technology by mutant S. cerevisiae BJM
Arshad,Muhammad; Hussain,Tariq; Iqbal,Munawar; Abbas,Mazhar.
Abstract Very high gravity (VHG) technology was employed on industrial scale to produce ethanol from molasses (fermented) as well as by-products formation estimation. The effect of different Brix° (32, 36 and 40) air-flow rates (0.00, 0.20, 0.40, and 0.60 vvm) was studied on ethanol production. The maximum ethanol production was recorded to be 12.2% (v/v) at 40 Brix° with 0.2 vvm air-flow rate. At optimum level aeration and 40 Brix° VHG, the residual sugar level was recorded in the range of 12.5-18.5 g/L, whereas the viable cell count remained constant up to 50 h of fermentation and dry matter production increased with fermentation time. Both water and steam consumption reduced significantly under optimum conditions of Brix° and aeration rate with...

Production and characterization of PHA from recombinant E. coli harbouring phaC1 gene of indigenous Pseudomonas sp. LDC-5 using molasses BJM
Saranya,V; Shenbagarathai,R.
Polyhydroxyalkanoates (PHA) are biodegradable and biocompatible green thermoplastics, synthesized by wide variety of bacteria as an intracellular carbon and energy storage intermediate. They are used as an alternative to nonrenewable petroleum derived plastics. The current interest in these biopolyesters is stimulated by the search for cost-effective capitalized production. This paper attempts to achieve maximized production rate from recombinant system using inexpensive substrate. Molasses from agro-industrial waste was used to produce PHA from recombinant E.coli in batch culture. PHA yield in molasses (3.06g/L ± 0.05-75.5%) was higher than that of sucrose (2.5g/L ± 0.05 - 65.1%). Properties of the polymer produced from molasses and sucrose were analyzed...

Media components and amino acid supplements influencing the production of fruity aroma by Geotrichum candidum BJM
Pinotti,T.; Carvalho,P.M.B.; Garcia,K.M.G.; Silva,T.R.; Hagler,Allen Norton; Leite,S.G.F..
The ability of Geotrichum candidum to produce fruity aroma in food grade sucrose, molasses, corn steep liquor and peptone based culture media was tested by sensory evaluation and analyzed by gas chromatography mass spectrometry. A strong and sweet fruity aroma was produced from molasses, with peptone or corn steep liquor stimulating aroma production. Molasses with peptone supplemented with leucine, valine, or alanine yielded better fruity aroma production and the presence of many esters was consistent with the fruity aroma production.

Yuan,XianJun; Dong,ZhiHao; Desta,Seare Tajebe; Wen,AiYou; Zhu,Xiaoxuan; Rong,Ting; Shao,Tao.
ABSTRACT: Ensilage is a simple and low-cost strategy to enable long term preservation and environmentally friendly utilization of agricultural by-products, such as straws and distiller's grains (DG) for ruminants. Effect of mixing different proportions of DG and rice straw (i.e. 0, 10, 20 or 30% of DG) with or without 5% molasses addition on fermentation and chemical variables of silages was evaluated. The study was conducted as a randomized blocks design in a 4 × 2 factorial arrangement, with three replications, using laboratory silos of 1L capacity (n=24). Despite a significant interaction (P<0.01) between DG and molasses addition was observed for most variables, in general the increased addition of DG linearly decreased the pH value, acetic acid...
