“…The result of untreated water was (120MPN/100ml) for the both samples. Filtration and addition of Acacia ( Acacia Nilotica) reduce the microbial load for the surface sample to (4MPN/100ml) compared to a reduction of (7 MPN/100ml ), for ground sample when treated by ltration, the water sample collected from surface source followed the same trend for that of water collected from ground source when treated with Acacia, were high reduction of microbial load was noted (4 MPN/100ml) for surface sample compared to (11MPN/100ml ) for ground sample (Rini et al, 2023).…”

Background: Acacia nilotica was found to have algicidal, anti-protozal, antibacterial and antifungal effects. The present study aimed to identify the role of three treatment methods on physical, chemical, microbiological changes occurring in two water samples. The two samples were obtained from two rural villages. The methods used were, addition of Acacia nilotica seed, Shap stone (a tradition substance) and cloth filtration techniques. Results: Results showed that Fluoride, Chloride, and Total hardness, of water samples were (0.73 mg/l, 756 mg/l, 292 mg/l; 0.79mg/l, 220, and 224mg/l) respectively for untreated water sample collected from surface source and for other sample collected from ground source were respectively, trace iron was reported for ground water. A high level of Turbidity was record for both untreated water samples (50.3NTU for surface sample and 22.4NTU for ground sample). High microbial results (120 MPN/100ml) of untreated water were recorded. The addition of Acacia nilotica seed to both samples lead to partial reduction of chemical properties of water. Cloth Filtration technique reduce the turbidity level for both samples to 2.6 and 28.2 NTU for water collected from surface and ground source, respectively. Conclusions: The three methods have antimicrobial effect, result indicate a high reduction in the microbial contamination reached to 4 and 6 MPN/100 Ml. There was statistical difference (P < 0.05) regard to microbial contamination between the sample from surface source and sample from ground source.

In recent years, nanocellulosic materials have attracted special attention because of their performance in different advanced applications, biodegradability, availability, and biocompatibility. Nanocellulosic materials can assume three distinct morphologies, including cellulose nanocrystals (CNC), cellulose nanofibers (CNF), and bacterial cellulose (BC). This review consists of two main parts related to obtaining and applying nanocelluloses in advanced materials. In the first part, the mechanical, chemical, and enzymatic treatments necessary for the production of nanocelluloses are discussed. Among chemical pretreatments, the most common approaches are described, such as acid- and alkali-catalyzed organosolvation, 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidation, ammonium persulfate (APS) and sodium persulfate (SPS) oxidative treatments, ozone, extraction with ionic liquids, and acid hydrolysis. As for mechanical/physical treatments, methods reviewed include refining, high-pressure homogenization, microfluidization, grinding, cryogenic crushing, steam blasting, ultrasound, extrusion, aqueous counter collision, and electrospinning. The application of nanocellulose focused, in particular, on triboelectric nanogenerators (TENGs) with CNC, CNF, and BC. With the development of TENGs, an unparalleled revolution is expected; there will be self-powered sensors, wearable and implantable electronic components, and a series of other innovative applications. In the future new era of TENGs, nanocellulose will certainly be a promising material in their constitution.

The use of fishponds as a storage container for fresh ground chilies has been carried out. Changes in metabolites in ground chili were observed during storage in fishponds and compared with refrigerator. This study was done to determine whether the preservation mechanism in fishponds and refrigerators is the same. Fresh chili samples were stored in plastic containers and then placed in fishponds and refrigerators. The temperature of fishpond storage was at ± 26ºC while that of refrigerator was at ± 8ºC. Total microbes, sugars, capsaicinoids, and amino acids in the stored ground chilies were analyzed. The analysis was performed periodically at 0, 1, 2, and 4 weeks. It was known that the quality of ground chili that was stored for one month in a fishpond and ground chili were the same. In addition, the profile of changes in total microbial growth, sugar, and capsaicinoids in ground chilies during storage had the same pattern between storage in fishponds and refrigerators. Meanwhile, the amino acid profile looks different between fishponds and refrigerators. From this research, it can be concluded that preserving ground chilies stored in fishponds also seem to inhibit enzymatic activity, but without decreasing the metabolic activity due to the temperature. This finding needs further clarification to develop conservation techniques using this environmentally friendly fishpond.
