Опубликована: Ноя. 18, 2021

Fossil fuels are a major contributor to climate change, and as the demand for energy production increases, alternative sources (e.g., renewables) becoming more attractive. Biofuels such bioethanol reduce reliance on fossil can be compatible with existing fleet of internal combustion engines. Incorporation biofuels engine (ICE) carbon dioxide emissions. Bioethanol is typically produced via microbial fermentation fermentable sugars, glucose, ethanol. Traditional feedstocks first-generation feedstock) include cereal grains, sugar cane, beets. However, due concerns regarding food sustainability, lignocellulosic (second-generation) algal biomass (third-generation) have been investigated. Ethanol yield from dependent multitude factors. This review compares range feedstocks, elaborates available technologies, including practices. The importance maintaining nutrient homeostasis yeast also examined. purpose this provide industrial producers policy makers insight into yields achieved by current manufacturing practices, goals future innovation.

Pullulanase: unleashing the power of enzyme with a promising future in the food industry

Frontiers in Bioengineering and Biotechnology, Год журнала: 2023, Номер 11

Опубликована: Июнь 28, 2023

Pullulanases are the most important industrial group of enzymes in family 13 glycosyl hydrolases. They hydrolyze either α-1,6 and α-1,4 or both glycosidic bonds pullulan as well other carbohydrates to produce glucose, maltose, maltotriose syrups, which have uses food related sectors. However, very less reports available on pullulanase production from native strains because low yield issues. In line with increasing demands for pullulanase, it has become search novel pullulanase-producing microorganisms high yields. Moreover, costs major limitations enzymes. The cost by using solid-state fermentation (SSF) process can be minimized selecting agro-industrial waste. This review summarizes types, sources, strategies, potential applications different industries. Researchers should focus fungal producing better agro-waste. It will prove a enzyme processing industries surely reduce products.

Integration of Solid State and Submerged Fermentations for the Valorization of Organic Municipal Solid Waste

Journal of Fungi, Год журнала: 2021, Номер 7(9), С. 766 - 766

Опубликована: Сен. 16, 2021

Solid state fermentation (SsF) is recognized as a suitable process for the production of enzymes using organic residues substrates. However, only few studies have integrated an evaluation feasibility applying produced by SsF into subsequent hydrolyses followed target compounds, e.g., lactic acid (LA), through submerged-liquid fermentations (SmF). In this study, wheat bran (WB) was used substrate via Aspergillus awamori DSM No. 63272. Following optimization, cellulase and glucoamylase activities were 73.63 ± 5.47 FPU/gds 107.10 2.63 U/gdb after 7 days 5 fermentation, respectively. Enzymes then hydrolysis fraction municipal solid waste (OFMSW). During hydrolysis, glucose increased considerably with final value 19.77 1.56 g/L. Subsequently, hydrolysates fermented in SmF Bacillus coagulans A166 increasing LA concentration 15.59 The data reported study provides example how technologies can be combined valorization WB OFMSW.

Waste to protein: A systematic review of a century of advancement in microbial fermentation of agro‐industrial byproducts

Comprehensive Reviews in Food Science and Food Safety, Год журнала: 2024, Номер 23(4)

Опубликована: Июнь 12, 2024

Abstract Increasing global consumption of protein over the last five decades, coupled with concerns about impact on emissions animal‐based production, has created interest in alternative sources. Microbial proteins (MPs), derived through fermentation agro‐industrial byproducts, present a promising option. This review assesses century advancements this domain. We conducted comprehensive and meta‐analysis, examining 347 relevant research papers to identify trends, technological advancements, key influencing factors production MP. The analysis covered types feedstocks microbes, methods, implications nucleic acid content food‐grade quality proteins. A conditional inference tree model Bayesian factor were used ascertain various parameters content. Out all studied parameters, such as type feedstock (lignocellulose, free sugars, gases, others), (solid, liquid, gas), microbe (bacteria, fungi, yeast, mix), operating (temperature, time, pH), identified largest influences Gas liquid demonstrated higher content, averaging 52% 42%, respectively. Among bacterial species produced 51%. suitable pH, temperature, also for different microbes. results point opportunities continued innovation feedstock, regulatory alignment fully realize potential MP contributing food security sustainability goals.

A narrative action on the battle against hunger using mushroom, peanut, and soybean-based wastes

Frontiers in Public Health, Год журнала: 2023, Номер 11

Опубликована: Май 11, 2023

Numerous generations have been affected by hunger, which still affects hundreds of millions people worldwide. The hunger crisis is worsening although many efforts made to minimize it. Besides that, food waste one the critical problems faced most countries It has disrupted chain system due inefficient management, while negatively impacting environment. majority from production process, resulting in a net zero for manufacturers also harnessing its potential. Most wastes are high nutritional and functional values, yet them end up as low-cost animal feed plant fertilizers. This review identified key emerging line mushroom, peanut, soybean (MPS). These (MPS) provide new source conversion their content, contributes circular economy post-pandemic era ensures security. In order achieve carbon neutrality effective management alternative foods, biotechnological processes such digestive, fermentative, enzymatic conversions essential. article provides narrative action on potential application challenges MPS future foods battle against hunger.
