Biosurfactant production by some bacterial isolates using molasses, milk whey and cassava flour wastewater (manipueira) as substrates was evaluated and compared with the production in conventional medium. Isolates growing in manipueira medium decreased the surface tension around 42%, the highest reduction among all the substrates tested. From the eleven isolates tested, eight were able to decre...

Aerobic operation of an immersed hollow fibre membrane bioreactor, treating municipal wastewater supplemented with molasses solution, has been studied across mixed liquor suspended solids (MLSS) concentrations between 8 and 32 g L(-1), the higher concentrations being normally associated with thickening operations. Only a marginal loss in membrane permeability was noted between 8 and 18 g L(-1) ...

background: l-tryptophan is used widespread in the pharmaceutical industry. the majority of l-trp production depends on microbial processes that produce l-tryptophan from indole and l-serine. these processes are very costly due to the costs of precursors, especially l-serine. use of inexpensive substitutions as the l-serine source of l-tryptophan production enables us to reach a cost-effective ...

Viscosity of molasses is determined under standard conditions (50°C, 80% Karl Fischer solids) using a Hoeppler viscosimeter. Samples are pretreated by dilution and concentration under vacuum to dissolve crystal and remove air. Measurements are made at two different concentrations, preferably slightly below and slightly above 80% solids and the required value obtained by extrapolation using the ...

The radiation of 14C is very weak 14C+ 14N t PSucrose in first expressed juice and mixed juice was determined by isotope dilution and the results were compared with the conventional pol determination. i t was found that the sucrose content on the average was 0,25% higher using the ID method. Molasses samples, on the contrary, showed a sucrose content which was 0,71% lower than the value found b...

A total of 24 castrated male Creole were used for digestibility studies on three sugarcane (SC) products: final molasses, SC juice and ground SC. Digestibility of macronutrients were determined in three consecutive experimental trials between 35 and 60 kg BW. The first trial measured the effect of a constant rate of incorporation of those SC products in a control diet (23% on a dry matter (DM) ...

Activated carbon is used in sugar industries for the removal of colorants from sugar liquor and for treatment of drinking water and industrial wastewater. Coal is a commercially used activated carbon, which is a limited non renewable resource. There are different renewable resources such as sugarcane Bagasse, Almond nutshells, Rice husk, Rice straw, Coconut shells, which could be used as altern...

The Indonesian government is gradually reducing its dependence on petroleum fuels by mixing it with biofuels. One of the biofuels used bioethanol made from molasses. This study aims to analyze potential for sugarcane development at farm level, identify bioenergy problems, and provide recommendations based research was conducted in East Java Province 2016, updated data 2019. analytical methods w...

Pichia veronae strain HSC-22 (accession number KP012558) showed a good tolerance to relatively high temperature, ethanol and sugar concentrations. Response surface optimization based on central composite design of experiments predicted the optimal values of the influencing parameters that affect the production of bioethanol from sugarcane molasses to be as follows: initial pH 5, 25% (w : v) ini...

We address recent developments in the exploration of quantum nuclear dynamics in large, Ðnite, low-temperature systems, focusing on BoseÈEinstein condensates (T ^ 100 nK), optical molasses (T ^ 10È100 lK) and aromatic clusters (T \ 0.4 K). The expansion of optical molasses bears a close analogy molecule ÉHe n to the nuclear dynamics of Coulomb explosion of multicharged clusters. Spectroscopy of...
