Summary: Bananas produce over 114 million metric tons annually, and their peel, which makes up one-third of the fruit's weight, is commonly discarded but has healing potential. The peel contains potent antioxidants and compounds like pectin, which can be extracted for pharmaceutical and food industry use. Current extraction methods, such as ultrasound-assisted extraction and subcritical water extraction, show promise for future research and applications.

Summary: Microorganisms have been extensively studied and used for the production of various enzymes and bioactive substances. Cellulases, as essential enzymes for industrial applications, have found widespread use in bioprocessing and biotransformation purposes. However, the mass-scale and low-cost production of cellulase enzymes face challenges due to the lack of cheap and effective fermentation substrates. This review explores the utilization of banana peels as a potential food waste substrate for cellulase enzyme production, as well as the applications of cellulase enzymes as antimicrobial agents.

Summary: This study focused on utilizing agricultural pectin-containing by-products to produce pectinases using the Bacillus amyloliquefaciens TKU050 strain. The highest pectinase productivity was achieved with 0.5% wheat bran-containing medium at 37 degrees C for four days. The purified pectinase showed optimal activity at 50 degrees C and pH 6, with a recovery ratio of 7.24% and specific activity of 0.51 U/mg. The pectinase exhibited inhibition by sodium dodecyl sulfate and Cu2+, but also demonstrated a growth-enhancing effect on lactic acid bacteria when used to hydrolyze banana peel.

Summary: In this study, functionalized banana peel biochar (BPB) was prepared by microwave-assisted pyrolysis for the first time to investigate its adsorption to malachite green (MG) dye. The maximum adsorption capacity of BPB500 and BPB900 to malachite green reached 1790.30 and 2297.83 mg.g(-1) within 120 min. The adsorption mechanism of MG dye on BPB included hydrophobic interaction, hydrogen bonding, pi-pi interaction, n-pi interaction, and ion exchange. Furthermore, BPB showed great potential for practical applications in simulated wastewater treatment experiments and cost calculations.

Summary: This study investigated the use of gastropoda shells as a calcium source for the synthesis of hydroxyapatite (HAP), and found that the biogenic HAP derived from these shells had poor antibacterial properties. To improve the antibacterial property, Musa paradisiaca sap was added to the formation of a biocomposite with HAP. The results showed that the nano-HAP/M. paradiasica sap biocomposite had a controlled shape and exhibited higher resistance against bacterial growth. The in vitro cell viability assay confirmed the biocompatibility of the synthesized biocomposite.

Summary: Natural (Caprine bone) Hydroxyapatite/Phyllanthus acidus and Gallium substituted Hydroxyapatite/Phyllanthus acidus composite powders were successfully synthesized by thermal decomposition method. The synthesized powders were characterized for functional groups, phase purity, and crystalline size. The results showed that the substitution of Gallium led to a reduction in the size of Hydroxyapatite powders, resulting in finer powders and a uniform surface morphology. Gallium substituted Hydroxyapatite/Phyllanthus acidus composite exhibited better antibacterial activity compared to Hydroxyapatite/Phyllanthus acidus composite.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
