Abstract:

The present study evaluated the storage stability of Lactobacillus helveticus (NCDC-292) fermented, freeze-dried chicken liver and heart protein hydrolysates. The resulting chicken liver hydrolysate powder (CLHP) and chicken heart hydrolysate powder (CHHP) were stored aerobically in PET jars at room temperature (27 ± 2°C) and analyzed over a 90-day period at 30-day intervals. Parameters assessed included pH, water activity, lipid oxidation, antioxidant activity, and microbial load. No significant changes in pH were observed throughout the storage period. However, water activity and TBARS value

Abstract:

Flavor and aroma cannot be separated in food industries. The manipulation of the ingredients to increase the taste has started since early civilization. Common example of the earliest application of ingredients to increase the savory taste of the food is soy sauce production. The process of digging out the aroma and flavor includes frying, stewing, grilling as well as fermenting. Nowadays, much complex savory system in food can be achieved through several processes such as Maillard reaction and protein hydrolysate production. The food produced will not only be tasty but healthy. This concept w

We constructed a multifunctional Pseudomonas putida KT2440 to simultaneously secrete PET hydrolase LCC, a leaf-branch compost cutinase, and synthesize muconic acid (MA) using the PET hydrolysate.

ABSTRACT Dilute acid pretreatment is an established method for hydrolyzing the methylglucuronoxylans of hemicellulose to release fermentable xylose.

Enterobacter asburiae JDR-1, isolated from colonized wood, was found to efficiently ferment both methylglucuronoxylose and xylose in acid hydrolysates of sweet gum xylan, producing predominantly ethanol and acetate.

Abstract:

Globally, an estimated 7.4 billion tons of plastic have accumulated, with projections suggesting this could escalate to 40 billion metric tons by 2050. Unfortunately, only about 10% of this plastic is recycled, due to the lack of sustainable and economical solutions [1]. Alarmingly, over 70% of plastic waste ends up in landfills or oceans where it gradually decomposes into small particles (average diameter less than 5 mm), often referred to as microplastics (MPs). This widespread presence of microplastics poses a significant hazard to global ecosystems and human health. Microplastics can be in

Abstract:

Nine Lactobacillus strains known for surface proteinase activity were chosen from our collection and tested for their ability to grow in pea seed protein-based medium, and to hydrolyze purified pea proteins in order to produce peptides with antioxidant (AO) activity. Two strains, Lactobacillus rhamnosus BGT10 and Lactobacillus zeae LMG17315, exhibited strong proteolytic activity against pea proteins. The AO activity of the pea hydrolysate fraction, MW <10 kDa, obtained by the fermentation of purified pea proteins with Lactobacillus rhamnosus BGT10, was tested by standard spectrophotometric

Abstract:

Cancer has high prevalence rate and mortality with conventional chemotherapy and other management protocols being both expensive and inaccessible especially in low/medium income countries (LMIC). Sourcing alternative cheaper and easily accessible treatment from blends of antioxidants sources can reduce the burden of cancer on patients. This work therefore seeks to produce a blend from the protein hydrolysates of shrimp shell waste, germinated soybean and germinated pigeon pea which not only has high antioxidant activity but also can inhibit cervical cancer cell proliferation.

Abstract:

Enzymatic hydrolysates of honeybee-collected pollen were prepared using food-grade proteinase and aminopeptidases entirely of plant origin. Bromelain from pineapple stem was applied (8 mAU/g substrate) in the first hydrolysis stage. Aminopeptidase (0.05 U/g substrate) and proline iminopeptidase (0.03 U/g substrate) from cabbage leaves (Brassica oleracea var. capitata), and aminopeptidase (0.2 U/g substrate) from chick-pea cotyledons (Cicer arietinum L.) were involved in the additional hydrolysis of the peptide mixtures.

After isolation of the main constituent, there are abundant remains which represent an inexpensive material that has been undervalued until now. Pea peel waste i

Abstract:

This short paper reviews two groups of enzymes designated as polyethylene terephthalate (PET) hydrolases: one consists of thermophilic cutinases from thermophilic microorganisms (actinomycetes and a fungus) and the other consists of mesophilic cutinases, the representative of which is IsPETase from a mesophilic bacterium. From the viewpoint that PET hydrolysis requires a high temperature close to the glass transition temperature (65–70 °C in water) of PET, mesophilic cutinases are not suitable for use in the enzymatic recycling of PET since their degradation level is one to three orders of mag

The conjugation of photosensitizer with collagen seems to be a very promising approach for innovative topical photodynamic therapy (PDT). The study aims to evaluate the effects of bovine collagen hydrolysate (Clg) on the properties of gallium (III) phthalocyanine (GaPc) on pigmented melanoma. The interaction of GaPc with Clg to form a conjugate (GaPc-Clg) showed a reduction of the intensive absorption Q-band (681 nm) with a blue shift of the maximum (678 nm) and a loss of shape of the UV-band (354 nm).

The objective was to investigate the anti-adipogenesis potential of selected legume protein hydrolysates (LPH) and combinations using biochemical assays and in silico predictions. Black bean, green pea, chickpea, lentil and fava bean protein isolates were hydrolyzed using alcalase (A) or pepsin/pancreatin (PP). The degree of hydrolysis ranged from 15.5% to 35.5% for A-LPH and PP-LPH, respectively. Antioxidant capacities ranged for ABTS•+ IC50 from 0.3 to 0.9 Trolox equivalents (TE) mg/mL, DPPH• IC50 from 0.7 to 13.5 TE mg/mL and nitric oxide (NO) inhibition IC50 from 0.3 to 1.3 mg/mL.

Abstract:

The degree of decomposition of 30 organic soils from southern Superior Province of the Precambrian Shield was investigated by comparing the cellulose component, measured as glucose in the acid hydrolysate, with the aerobic respiration rate and with the rubbed fiber content of the soils. Bivarient analyses of these parameters show reasonable correlation. It is suggested, therefore, that cellulose determination is suitable for assessing the biodegradation potential of organic soils. The method is quantitative and less subject to operator error and variability than the fiber determinations, and m
