This study investigates the effectiveness of different anaerobic sludge inoculum in the removal of organic matter from sugar industry wastewater with varying initial COD concentrations. The inoculum was obtained from anaerobic treatment plants in Burdur, Eskiþehir, and Kastamonu, and were tested in batch reactors under three different wastewater concentrations: 6.360 g/L, 12.310 g/L, and 21.735 g/L of COD. The treatment efficiency was assessed through the COD removal percentage. The results of the variance analysis showed that both inoculum location and wastewater concentration had a significant impact on COD removal, with an R² value of 0.980, indicating a highly robust model. The Tukey HSD test revealed significant differences in organic matter removal efficiency between the inocula from Kastamonu, Burdur, and Eskiþehir, with Kastamonu demonstrating the highest efficiency. Additionally, higher wastewater concentration resulted in lower organic matter removal efficiencies, especially when the COD concentration increased from 6.360 g/L to 12.310 g/L. The interaction between inoculum location and wastewater concentration was also found to be significant, emphasizing the importance of both factors in optimizing anaerobic treatment processes. This study highlights the need for selecting appropriate inoculum and adjusting treatment conditions based on wastewater characteristics for improved anaerobic wastewater treatment performance.

The purpose of this study was to investigate the basic chemical properties of the cheese varieties to be obtained from dairies in Tire by determining whether they comply with the Turkish Food Codex Cheese Communiqué (Communiqué No: 2015/6) in terms of their microbiological content In our study, the highest fat content was found in FP samples with 30.0% ±0.72, and the lowest fat rate was 5.0%±2.06 in LP samples. The highest protein ratio was found in 23.0±11.2in ÖP, and the lowest protein was found in 13.0±5.6 ÇP samples. The highest pH was found in 5.7±2.08 TÝP samples, and the lowest pH was 4.8±1.08 in LP samples. Acidity (% in lactic acid) was found in LP samples with a value of 0.59±0.8, and the highest value was found in TÝP samples with 1.26±0.8. The highest salt content was found in 3.85±6.03% OP samples. The highest water activity was found in TIP samples with 0.98±0.15. When we review the microbiological analysis results, we saw that Propionibacterium spp. highest count was found in OP samples with 3.0x102 cfu/gr.The highest Enterococcal count was found in OP samples with 4.6x104 cfu/g. The highest Yeast and Mold Count was found in WP samples as 2.6x102 cfu/g. The highest count of Pseudomonas was found in BP samples as 6.0x102 cfu/gr. While Staphylococcus aureus count was not found in any samples, it was found in CAP samples as 1.2x101 kob/g.
From the results obtained in this study, we are of the opinion that infection and intoxication may occur from cheeses produced from raw milk and therefore may be a potential danger to public health.
