Increasing consumer demand for natural products have renewed food industry attention in bio preservation. Lactic acid bacteria are of particular interest as effective alternative to chemical preservation because of their food grade status. This work explores the effect of antifungal compounds produced by isolates of Lactobacillus sp on some selected pathogenic fungi growth. Samples of diary and fermented products were purchased from commercial vendors within the Federal Capital Territory (FCT) and screened for the presence of Lactobacillus sp. The Lactobacillus sp isolated were screened for antifungal activity against Aspergillus fumigatus, Candida albicans and Trichophyton rubrum using a dual culture assay. Strains with antifungal activity were identified and the fungal inhibitory activity was further evaluated. The effect of abiotic factors on the antifungal activity was evaluated by overlay assay under different temperature and pH. Majority of the identified isolates belonged to the genus Lactobacillus. Lactobacillus sp. produced antifungal compounds under different temperatures (25ºC, 30ºC and 37ºC). The antifungal compounds produced by Lactobacillus strains showed greater inhibitory activity on Aspergillus fumigatus. At 30ºC the percentage zones of inhibition range were 44.4%- 60.4%. All isolates showed stronger antifungal activity when grown at pH 4.0 and 5.0. At a pH 2.0 there was a total inhibition of fungal growth however, there was no inhibition of fungal growth at the pH 7.0. Lactic acid bacteria can be employed as effective alternative to chemical preservatives in food. Temperature and pH of the culture medium could influence the production of antifungal compounds by lactic acid bacteria.

Candida albicans cause opportunistic infection of the oral cavity. Probiotic has health benefits, produces organic acids as anti-C. albicans. The aim of this research was to determine the antifungal activity of commercial fermented milk products against Candida and viability of bacteria in commercial fermented milk products. The antifungal activity was determined using well diffusion method. Viability of lactic acid bacteria was done by plate count method. The results show that commercial fermented milk productshas an activity of anti-C.albicans were shown by irradical zone formed around well containing fermented dairy products. Viability of lactic acid bacteria 107-1010 CFU/mL.

Fresh pasta is subjected to rapid spoilage, mainly due to the metabolic activity of bacteria, yeasts, and especially molds, which negatively affect the sensorial characteristics and the safety of the product. In this work, chickpea flour was fermented with selected lactic acid bacteria, characterized in terms of the antifungal activity, and used to fortify fresh semolina pasta. Pasta was characterized and subjected to a long period of storage after being artificially inoculated with Penicillium roqueforti. Conventional fresh semolina pasta, produced with or without calcium propionate addition, was used as a reference. The water/salt-soluble extract from chickpea sourdough exhibited antifungal activity towards a large spectrum of molds. Its purification led to the identification of ten potentially active peptides. Besides the high content of dietary fibers (4.37%) and proteins (11.20%), nutritional improvements, such as the decrease of the antinutritional factors concentration and the starch hydrolysis index (25% lower than the control) and the increase of the protein digestibility (36% higher than the control), were achieved in fresh pasta fortified with the chickpea sourdough. Inhibition of the indicator mold growth during a 40-day storage period was more effective than in pasta added to calcium propionate.

Bakteri Asam Laktat (BAL) yang terkandung dalam susu fermentasi akan menghasilkan asam-asam organik, hidrogen peroksida, diasetil, asetaldehid, asetoin, reutinin, reuterisiklin dan bakteriosin, dapat sebagai anti-Candida. Spesies Candida non-albicans seperti C. tropicalis dan C. glabrata sebagai penyebab kandidiasis oral cenderung meningkat. Tujuan penelitian ini mengetahui aktivitas antifungi susu fermentasi komersial pada Candida non-albicans dan viabilitas bakteri asam laktat di dalam susu fermentasi komersial. Aktivitas antifungi pada Candida non-albicans dilakukan dengan metode difusi sumuran. Viabilitas bakteri asam laktat dihitung berdasarkan jumlah bakteri asam laktat sebagai jumlah bakteri total (Total Plate Count). Hasil penelitian menunjukkan bahwa susu fermentasi komersial lebih mampu menghambat C. tropicalis dibandingkan C. glabrata. Viabilitas bakteri asam laktat dalam susu fermentasi komersial 107-1010 CFU/mL. Lactic Acid Bacteria (LAB) contained in fermented milk will produce organic acids, hydrogen peroxide, diacetyl, acetaldehyde, acetoin, reutinin, reuterycline and bacteriocin, as anti-Candida. Candida non-albicans species such as C. tropicalis and C. glabrata as causes of oral candidiasis tend to increase. The aim of this research was to determine the antifungal activity of commercial fermented milk against Candida non-albicans and viability of lactic acid bacteria in commercial ermented milk. The antifungal activity was determined using well diffusion method. Viability of lactic acid bacteria is calculated as Total Plate Count. The results showed that commercial fermented milk was more able to inhibit C. tropicalis compared C. glabrata. Viability of lactic acid bacteria 107-1010 CFU/mL.
