Mushroom β-Glucan Recovered from Antler-Type Fruiting Body of by Enzymatic Process and Its Potential Biological Activities for Cosmeceutical Applications.

Mushrooms are incredibly valuable macro fungi that are an important and integral part of the ecosystem. In addition to being used as cuisine, mushrooms have been used for medicinal purposes for many centuries. This research applied a process for recovering β-glucan (BG) from the antler-type fruiting body of as well as tested the biological activities related to cosmeceutical applications.

Functionality of Yeast β-Glucan Recovered from by Alkaline and Enzymatic Processes.

β-Glucan (BG), one of the most abundant polysaccharides containing glucose monomers linked by β-glycosidic linkages, is prevalent in yeast biomass that needs to be recovered to obtain this valuable polymer. This study aimed to apply alkaline and enzymatic processes for the recovery of BG from the yeast strain TISTR 5925. For this purpose, the yeast was cultivated to produce the maximum yield of raw material (yeast cells).

Incorporation of Tapioca Starch and Wheat Flour on Physicochemical Properties and Sensory Attributes of Meat-Based Snacks from Beef Scraps.

The global demand for healthy snacks with high protein content is growing annually. Meat scraps generated after meat cutting in the slaughtering process are considered a valuable protein product. The aim of this research was to formulate the meat-based snacks obtained from beef scraps by baking at 150 °C for 20 min.

Eco-Friendly Rice Straw Paper Coated with Longan () Peel Extract as Bio-Based and Antibacterial Packaging.

This study aimed to develop active paper from rice straw fibers with its function as antibacterial activity obtained from longan () peels. The morphology and mechanical properties of fibers of rice straw were examined as quality parameters for paper production. Rice straw paper (RSP) with basis weight ca 106.

Biosynthesized Poly(3-Hydroxybutyrate) on Coated Pineapple Leaf Fiber Papers for Biodegradable Packaging Application.

This paper is aimed at investigating the usage of biosynthesized poly(3-hydroxybutyrate) (P(3-HB)) for a coating on pineapple leaf fiber paper (PLFP). For this purpose, (P(3-HB)) was produced by BSRT1-1, a highly potential P(3-HB) producing bacterium, with a weight-average molecular weight () of 6.07 × 10 g/mol.

Production of poly(L-lactide)-degrading enzyme by Amycolatopsis orientalis for biological recycling of poly(L-lactide).

Efficient production of poly(L-lactide)(PLA)-degrading enzyme was achieved by addition of 0.1% (w/v) silk fibroin powder into a liquid culture medium of an actinomycete, Amycolatopsis orientalis, without other complex nitrogen sources, such as yeast extract and peptone. Scaled-up production of the enzyme in a 5-l jar fermenter showed the possibility of producing this enzyme on an industrial scale at low production cost.

Biodegradation of poly(L-lactide).

The biodegradation of poly(L-lactide) (PLA) is reviewed. The important role of actinomycetes in PLA degradation is emphasized. These PLA-degrading actinomycetes belong phylogenetically to the Pseudonocardiaceae family and related genera, including Amycolatopsis, Lentzea, Streptoalloteichus, Kibdelosporangium and Saccharothrix.

Poly(L-lactide) degradation by Kibdelosporangium aridum.

A new poly(L-lactide) (PLA)-degrading actinomycete, Kibdelosporangium aridum, degraded more than 97 mg out of 100 mg added high molecular weight PLA film (Mn: 3.4 x 10(5)) within 14 d in liquid culture. L-Lactic acid, the monomeric degradation product of PLA, was totally assimilated by the strain.

Poly(L-lactide) degradation by Saccharothrix waywayandensis.

Poly(L-lactide) (PLA) was degraded by more than 95 mg from 100 mg PLA film by an actinomycete, Saccharothrix waywayandensis, growing in 100 ml liquid culture containing 0.1% (w/v) gelatin. In addition to degrading PLA, this strain assimilated the major degradation product of PLA, L-lactic acid.
