“…Protein hydrolysate (PH) enables plants to assimilate more nutrients. pH encompasses a variety of amino acids and peptides that plants swiftly absorb and employ to facilitate the comprehensive growth and development of the entire plant structure [19]. Moreover, the utilization of PH also improves the uptake of essential nutrients crucial for plant growth, such as nitrogen and nitrate [20].…”

By controlling environmental conditions, indoor farming can increase plant growth, productivity, and harvest quality. An additional element that can enhance lettuce yield is the utilization of plant biostimulants. These substances can boost nutrient absorption efficiency, enhance resistance to environmental stresses, and foster positive impacts on plant growth and maturation. This study examined the impact of red and green romaine lettuce with different plant biostimulants (Viva®, Megafol®, Radifarm®) added to AB mix on lettuce growth under white LED lighting on 30 days of cultivation. The MANOVA tests showed that different varieties of romaine lettuce and plant biostimulants substantially affected chlorophyll b, total chlorophyll, leaf number, leaf area, leaf weight, and root weight. A polynomial growth model was also obtained from height data collected during 30 days of planting, with an optimal R2, RMSE, MAE, and MAPE reaching the optimal value of 0.9926; 0.50; 0.46; 1.72, respectively, for red lettuce with Viva®, and 0.9930; 0.11; 0.29; 2.37, respectively, for green lettuce with Viva®. In addition, Pearson Correlation analysis between each treatment indicated a positive and substantial correlation in various growth indices, up to 0.901.

“…Protein hydrolysate biostimulants are of growing interest in sustainable agriculture due to their significant effect on increasing crop yields under abiotic stress conditions [ 59 ]. These complex mixtures of amino acids and oligopeptides are produced under controlled conditions, either by chemical hydrolysis, enzymatic hydrolysis or a combination of both, from the proteins of plant or animal origin contained in residual sources, by-products or wastes of agroindustrial processes [ 60 , 61 , 62 , 63 , 64 ]. They are usually readily available at an affordable cost due to the abundance of the source raw materials [ 65 , 66 ].…”

Together with other abiotic stresses such as drought and high temperatures, salt stress is one of the most deleterious environmental factors affecting plant development and productivity, causing significant crop yield reductions. The progressive secondary salinisation of irrigated farmland is a problem as old as agriculture but is aggravated and accelerated in the current climate change scenario. Plant biostimulants, developed commercially during the last decade, are now recognised as innovative, sustainable agronomic tools for improving crop growth, yield, plant health and tolerance to abiotic stress factors such as water and soil salinity. Biostimulants are a disparate collection of biological extracts, natural and synthetic organic compounds or mixtures of compounds, inorganic molecules and microorganisms, defined by the positive effects of their application to crops. The growing interest in biostimulants is reflected in the increasing number of scientific reports published on this topic in recent years. However, the processes triggered by the biostimulants and, therefore, their mechanisms of action remain elusive and represent an exciting research field. In this review, we will mainly focus on one specific group of biostimulants, protein hydrolysates, generally produced from agricultural wastes and agroindustrial by-products—contributing, therefore, to more sustainable use of resources and circular economy—and primarily on the consequences of their application on the abiotic stress resistance of horticultural crops. We will summarise data in the scientific literature describing the biostimulants’ effects on basic, conserved mechanisms activated in response to elevated salinity and other abiotic stress conditions, such as the control of ion transport and ion homeostasis, the accumulation of osmolytes for osmotic adjustment, or the activation of enzymatic and non-enzymatic antioxidant systems to counteract the induced secondary oxidative stress. The collected information confirms the positive effects of biostimulants on crop tolerance to abiotic stress by enhancing morphological, physiological and biochemical responses, but also highlights that more work is needed to further establish the molecular mechanisms underlying biostimulants’ effects.

“…Several studies have demonstrated the signifcance of BAPs and their applicability in the pharmacological and pharmaceutical felds. Tey may also be used in crop development and cosmetology, though to a lesser level [179][180][181][182][183]. Tese bioactivities, especially the antibacterial potential, can be advantageous to the agri-food sector.…”

Bioactive peptides (BAPs) obtained from plants and microbes have been thoroughly explored and studied due to their prophylactic properties. The use of BAPs seems to be a promising substitute for several currently available antibiotics because of their antimicrobial properties against foodborne pathogens. BAPs have several other useful properties including antitumor, antihypertensive, antioxidant, antiobesity, and antidiabetic activities. Nowadays, scientists have attempted to recombinantly synthesize bioactive peptides to study their characteristics and potential uses, since BAPs are not found in large quantities in nature. Many pathogenic microorganisms including foodborne pathogens are becoming resistant to various antibiotics. To combat these pathogens, scientists are working to find novel, innovative, and safe antimicrobial agents. Plant- and microbe-based BAPs have demonstrated noteworthy antimicrobial activity against a wide range of pathogenic microorganisms, including foodborne pathogens. BAPs can kill pathogenic microorganisms by disrupting membrane integrity, inhibiting DNA and RNA synthesis, preventing protein synthesis, blocking protein activity, or interacting with certain intracellular targets. In addition, the positive effect of BAP consumption extends to gut microbiota modulation and affects the equilibrium of reactive oxygen species in the gut. This article discusses recombinant BAPs, BAPs generated from plants and microbes, and their antimicrobial applications and modes of action for controlling foodborne pathogens.
