“…The fish's body uses most of the provided feed to supply energy to fend off attacks from existing pathogens triggered by microplastic exposure. This is in line with Dias et al (2016) statement. Fish consume microplastics from feed, which build up in their bodies and inflict physical and chemical harm, including internal organ damage that disrupts the metabolic and immune systems.…”

The presence of microplastics in the waters is due to plastic garbage that is difficult to decompose. Tilapia that live in the water has a high tolerance for polluted environments, thus making them vulnerable to microplastic contamination. The most common type of microplastic found in water is polyvinyl chloride. The study aims to investigate the effects of microplastic exposure on Tilapia growth and survival. The research plan used a complete random design (CRD) with four treatments and three repetitions. Exposure to microplastics in fish is carried out through feeding, with doses: without microplastic addition; addition of 0.01 mg per 0.75 g of feed; addition of 0.1 mg for 0.75 g of feeding; and addition of 1 mg for every 0.75 grams of feed. The mixed microplastic feed was given three times a day at a dose of 5% of the fish's body weight. Growth and survival data are analyzed using Anova; if there is any real impact, then further testing is done using Duncan. The study's findings showed that adding microplastics to specific weight growth, absolute weight, absolute length, feed conversion ratio, and survival at a dose of 1 mg per 0.75 g of feed was significantly different from treating the animals without adding microplastics. Therefore, we can conclude that a dose of 1 mg per 0.75 g of feed will impact the growth and survival of tilapia.

“…Sugarcane is a crop extensively cultivated in many countries, such as Brazil, India and Colombia, where is used for ethanol and aliments production. The SCB is the residue generated in factories after sugarcane juice extraction (Souza Dias et al, 2016), with around 280 kg of SCB generated by ton of sugarcane processed (UNICA, 2015). It is a fibrous lignocellulosic material rich in polymeric sugars with low ash content, making it a promising raw material for biofuel production.…”

First-generation (1G) fuel ethanol production in sugarcane-based biorefineries is an established economic enterprise in Brazil. Second-generation (2G) fuel ethanol from lignocellulosic materials, though extensively investigated, is currently facing severe difficulties to become economically viable. Some of the challenges inherent to these processes could be resolved by efficiently separating and partially hydrolysing the cellulosic fraction of the lignocellulosic materials into the disaccharide cellobiose. Here, we propose an alternative biorefinery, where the sucrose-rich stream from the 1G process is mixed with a cellobiose-rich stream in the fermentation step. The advantages of mixing are 3-fold: (i) decreased concentrations of metabolic inhibitors that are typically produced during pretreatment and hydrolysis of lignocellulosic materials; (ii) decreased cooling times after enzymatic hydrolysis prior to fermentation; and (iii) decreased availability of free glucose for contaminating microorganisms and undesired glucose repression effects. The iSUCCELL platform will be built upon the robust Saccharomyces cerevisiae strains currently present in 1G biorefineries, which offer competitive advantage in non-aseptic environments, and into which intracellular hydrolyses of sucrose and cellobiose will be engineered. It is expected that high yields of ethanol can be achieved in a process with cell recycling, lower contamination levels and decreased antibiotic use, when compared to current 2G technologies.
