This study compares the efficiency of lactic acid production by separate hydrolysis and fermentation (SHF) or simultaneous saccharification (SSF) sugar beet pulp, a byproduct industrial production. In experiments, pulp was hydrolyzed using five commercial enzymes. A series shake flask fermentations were conducted selected strains bacteria (LAB). The differences in activities enzymes for degrading principal components reflected different yields total reducing sugars. highest after lowest...

To lower the risk of obesity, diabetes, and other related diseases, WHO recommends that consumers reduce their consumption sugars. Here, we propose a microbiological method to sugar content in red beet juice, while incurring only slight losses betalain maintaining correct proportion juice components. Several yeast strains with different metabolic activities were investigated for ability which resulted decrease extract level corresponding from 49.7% 58.2%. This strategy was found have...

An example of the implementation principles circular economy is use sugar beet pulp as animal feed. Here, we investigate possible yeast strains to enrich waste biomass in single-cell protein (SCP). The were evaluated for growth (pour plate method), increment (Kjeldahl assimilation free amino nitrogen (FAN), and reduction crude fiber content. All tested able grow on hydrolyzed pulp-based medium. greatest increases content observed Candida utilis LOCK0021 Saccharomyces cerevisiae Ethanol Red...

Abstract Fermentation processes have been known since ancient times and are widely used in the production of food, beverages, other areas. One most well‐known fermented products is bread. It plays an important role human nutrition because valuable compounds it contains. The growing population leads to increase global bread consumption bakery products. Simultaneously, developed countries, declining trends observed. Understanding complex interplay between socio‐economic dynamics, food...

It is estimated that approximately 25% of waste remains after the apple juice pressing process. Combining this biomass with valuable compounds creates potential for reuse. To create a cost-efficient ecological process without any expensive steps, aim research was to examine using non-Saccharomyces yeasts (Kazachstania barnettii D1, Hanseniaspora uvarum D9, and Wickerhamomyces anomalus D11) low-temperature valorisation pomace. The scope encompassed characteristics pomace evaluation yeast...

Large amounts of waste biomass are generated in sugar factories from the processing beets. After diffusion with hot water to draw beet pieces, a wet material remains called pulp. In this study, pulp was enzymatically depolymerized, and obtained hydrolyzates were subjected fermentation processes. Bioethanol, biomethane, biohydrogen produced directly substrate or combined mode. Stillage, distillery by-product, used as feedstock for anaerobic digestion. During biosynthesis ethanol, most...

Research into fermentative production of lactic acid from agricultural by-products has recently concentrated on the direct conversion biomass, whereby pure sugars are replaced with inexpensive feedstock in process production. In our studies, for first time, source carbon used is sugar beet pulp, generated as a by-product industrial this paper, we focus simultaneous saccharification lignocellulosic biomass and fermentation acid, using mixed cultures complementary assimilation profiles. Lactic...

Despite the significant progress in research, problem of finding an efficient method for producing bioethanol from renewable lignocellulosic waste materials remains unresolved. Our investigation aimed to assess efficacy ethanol production sugar beet pulp (SBP) utilising various approaches, including pretreatment variations, enzymatic processes, and microbial hydrolysis. research involved using post-cultivation concentrate T. viride LOCK 0588 grown SBP-based medium as a source enzymes. The...

The objective of this study was to develop a method for the thermally-assisted acidic hydrolysis waste biomass from sugar industry (sugar beet pulp and leaves) chemical biotechnological purposes. distillates, containing furfural, can be catalytically reduced directly into furfurayl alcohol or tetrahydrofurfuryl alcohol. sugars present in hydrolysates converted by lactic bacteria acid, which, catalytic reduction, leads propylene glycol. may also utilized microorganisms process cell...

Spent yeasts, a co-product from fermentation processes, are source for unconvential autolysis processes. In this study, five post-fermentation yeast strains that often used in processes were used: Saccharomyces cerevisiae Ethanol Red (Lessafre), Kluyveromyces marxianus LOCK 0026, K. NCYC 179, Scheffersomyces stipitis 1541 and Pichia angusta 495. Autolysis was conducted at 50°C 48 hours the presence of saponins Quillaja saponaria. The concentrations proteins free amino acids autolysates...
