“…Such compounds are important for the fermentation process, as they directly affect the yield of ethanol, an important biotechnological product obtained from renewable natural resources and clean energy concepts. (Fiorini et al, 2016;Batista et al, 2018) The amino acid content varied between sorghum and sugarcane saccharin substrates. The saccharine sorghum broth had greater amino acid concentrations.…”

Energy cultures are emerging as viable renewable energy sources because they satisfy sustainability requirements. The present study involves a survey regarding the technological characteristics for sugarcane and sweet sorghum energy crops, in addition to their potential for bioethanol production. An exploratory survey was conducted regarding the agronomic and technological characteristics of cane and sorghum. Pre-inmates were produced with YPSAC 5% liquid medium, sterilized and 0.10 grams of yeasts FT858 and Pedra-2 were inoculated and incubated at 30 °C for 10 h at 250 rpm. After the production, the cells were recovered by centrifugation, at 105 rpm, resulting in a 10 mg mg-1 concentration of moist dough. This dough was subsequently inoculated in the fermentative medium consisting of a base of sorghum broth and cane without pH correction with a 22 °Brix. Ethanol was analysed by gas chromatography and amino acids by high-efficiency liquid chromatography. Sorghum broth presented a greater availability of serine, arginine, alanine, threonine, and tryptophan amino acids. Yeast hers presented fermentative efficiency for both substrates, but the largest ethanol production occurred in sorghum broth. The results demonstrated that sugar sorghum may be used for energy purposes.

“…The cultivars of sorghum [Sorghum bicolor (L.) Moench] termed 'sweet sorghum' have stems rich in fermentable sugars which can serve as raw material for ethanol production. Accordingly, it is seen as a promising gap filler for ethanol production between sugarcane crops, i.e., when the sugarcane has yet to ripen and bears only a low sucrose concentration (Kim and Day, 2010;Purcino and Durães, 2011;Fiorini et al, 2016).…”

“…The sorghum plant's C 4 metabolism offers high efficiency of solar radiation, resulting in a photosynthetic ranging from 30 to 100 mg dm -2 h -1 CO 2 , depending on, among other factors, the plant genotype (Magalhães and Durães, 2003;Santos et al, 2015). Sweet sorghum varieties, particularly, can reach up to 3 m in plant height and produce between 40 and 60 mg ha -1 in biomass (Fiorini et al, 2016). Thanks to its efficient root system, high number of secondary roots and effective maintenance of its internal water content through stomatal closure sorghum is a strongly drought-resistant crop.…”

Interspecific Competition Between Sweet Sorghum and Weeds

While evidence is mounting that sweet sorghum [Sorghum bicolor (L.) Moench], an ethanol crop, may provide an alternative to sugarcane (Saccharum officinarum L.) on sugarcane lands under rehabilitation, little is known of its under production limiting factors (e.g., interspecific competition with weeds). Accordingly, the aim of the present study was to identify the initial mutual interspecific competition between sweet sorghum hybrids and weeds in high infestation situations. The experiment was carried out in pots, using a 5 × 6 factorial design: (i) a sorghum-free control and four sweet sorghum hybrids (CVSW 81198, CVSW 80007, CVSW 80147 and XBSW 82158), besides a control without sweet-sorghum, and (ii) five species of weeds [Cyperus rotundus L., Mucuna aterrima (Piper and Tracy) Holland, Brachiaria decumbens Stapf, Ipomoea hederifolia L. and Digitaria nuda Schumach.], besides a weed-free control. M. aterrima was the only weed whose dry mass was not reduced by the presence of sweet sorghum. The hybrids of sweet sorghum did not suffer developmental interference from C. rotundus, I. hederifolia or D. nuda. On the other hand, these weeds dry mass was reduced through competition with sweet sorghum. The sweet sorghum cohabiting with B. decumbens or M. aterrima has its aboveground and leaf dry mass reduced. Sweet sorghum is a high competitive and robust plant and, even when under a high weed density, suffers little interspecific interference from certain species of the weed community.
