A lab-scale ensiling study was carried out to investigate the fermentation quality of water hyacinth (WH) supplemented with molasses, rice bran, as an absorbent, and an inoculant in the form of fermented vegetable juice and their combinations. After wilting the water hyacinths for 7 h to a dry matter (DM) content of 240 to 250 g/kg, the following treatments were applied: i) Control (C), WH only...
BACKGROUND Due to its cost-effectiveness and rich sugar composition, sugarcane molasses is considered to be a promising carbon source for biorefinery. However, the sugar mixture in sugarcane molasses is not consumed as efficiently as glucose in microbial fermentation due to complex interactions among their utilizing pathways, such as carbon catabolite repression (CCR). In this study, 2,3-butane...
We demonstrate sub-Doppler cooling of K on the D1 atomic transition. Using a gray molasses scheme, we efficiently cool a compressed cloud of 6.5 × 10 atoms from ∼ 4 mK to 20μK in 8 ms. After transfer in a quadrupole magnetic trap, we measure a phase space density of ∼ 10−5. This technique offers a promising route for fast evaporation of fermionic K. Introduction. – Cooling of fermionic atomic s...
The chemical composition, in situ rumen degradability coefficients of dry matter (DM) and crude protein (CP), in vitro gas production and in vivo digestibility were evaluated for olive cake (OC) silage treated (DM basis) with different additives as follows: (1) untreated OC; (2) OC, 8% molasses and 0.4% formic acid and (3) OC, 8% molasses, 0.4% formic acid and 0.5% urea. After addition of the...
background and objectives: the essential amino acid l-tryptophan can be produced by a condensation reaction between indole and l-serine, catalyzed by b. subtilis with tryptophan synthase activity. application of the tryptophan is widespread in the biotechnology domain and is sometimes added to feed products as a food fortifier. materials and methods: the optimum concentration of the iranian can...
The aim of this work was to study the production of polyhydroxyalkanoates (PHAs) by Bacillus subtilis and Escherichia coli isolated from the industrial contaminated soil samples using cane molasses as an inexpensive substrate. The amount of PHA accumulated followed a similar pattern to its growth for each of treatment indicating a growth-related production, yielding maximum PHA production of 54...
This simulation study was to evaluate low cost feeding strategies in response to higher cost of commercial concentrates to maintain current milk sales from dual purpose cattle herds in the humid lowlands of western Venezuela. Data were from farm surveys in 1987 and 1988. Baseline net margins from milk and beef per cow per year were $132 and $99 for two farm cases with average dally milk of 10 a...
Agro-industrial wastes have been used as substrate-support in solid state fermentation for enzyme production. Molasses and sugarcane bagasse are by-products of sugar industry and can be employed as substrates for invertase production. Invertase is an important enzyme for sweeteners development. In this study, a xerophilic fungus Aspergillus niger GH1 isolated of the Mexican semi-desert, previou...
